18650 Lithium-Ion Battery Harvesting From Old Laptop Battery Pack

[@Laziter73]

I do harvesting of batteries myself. Just the other day I pulled 6 fully working cells out of a 2010 HP laptop battery. They all took around 2600 mAh of charge each, which incidently is their rating. Best thing about these; They were 100% free. Some guy just wanted to throw his broken laptop out with everything in and to it. I didn't hesitate asking if I could have it. I now use them for testing of my powerbanks.

[@richardlloydusa]

+Laziter73 Cool. Thanks.

[@googleplusisdead]

Thanks, very interesting. I'm not interested in the batteries, but to rebuild a laptop battery pack. After a bit of work, got my HP pack opened, and lo and behold, there were only 4 batteries, but room for 8! The other 4 had plastic pieces the same size as the batteries... :) If I can find some good batteries for this pack at a reasonable price, I may go ahead with 8! Thanks again, RichE

[@richardlloydusa]

You are most welcome. I would not recommend modifying it as it could be hazardous to you or your equipment a new battery pack for your HP can be had for as little as $14.88 at Amazon: amzn.to/1O5tHJq. Thanks and all the best.

[@electronicshelpcare]

This laptop battery is the best quality, I also made one power bank by using the laptop battery.

[@richardlloydusa]

Thank you for watching, commenting and the valuable feedback. I appreciate it greatly. All the best. 👍😀

[@PolakeXD]

If you charge those 18650 Batteries and want to do a battery pack or put two in parallel then you should better use an balance charger. I used a lot of 18650 charger and they all showed 100% charge but some of the cells had 4.172v and some other ones 4.185v ... Since I discovered this I use a SkyRC Imax B6AC V2 balance charger which I bought from a trusted site which sells RC Hobby stuff.

[@nihonbunka]

I use these in my bicycle lights. I just jam a screwdriver in the connector hole after removing the contacts and work quickly! I leave the metal tabs on the plus ends so that they protrude more to get a better contact with the lights and charger since they are pretty flush with the surrounding plastic. If the tabs do not remain on the battery (which are dangerous as this videographer says) then I sometimes use a spike to level the plus end up more to make sure it touches the connector of my cheap lights. As you can see in this video too, it is difficult get a good contact to the batteries sometimes since they are made to be soldered to gether and not go in a light. I find that they are better than trustfire/ultrafire which are probably reused car etc batteries anyway.

[@odouls779]

If your charger is rated 1.5 volts, it can not charge a 3.7 volt battery. It will indicate it to be fully charged because the battery has a higher voltage than the charger.

[@richardlloydusa]

+Odouls77 Thanks.

[@grayanderson6840]

I did exactly the same with an old Toshiba laptop battery. The battery would not charge and I ended up buying a new battery for my laptop which worked fine and charged and lasted a long time. I then decided to take the old apart but very carefully as these things can easily catch fire if you stick a screwdriver through the side accidentally. I found the all 6 of my 18605's were all working fine and exactly the same as these here on this video. All of them were fine and I still have them now a few years later. You know what I think???? I think there is some sort of a clock on the circuit board of the laptop battery to tell it to stop working so you then have to go out to buy a new one. It is a big money making rip off and of course they tell you not to take the batteries apart. They would say that wouldn't they? If I ever need any 18650 batteries now I will buy second hand or even new laptop batteries from eBay. It is a cheaper way of getting these batteries and the 18650 batteries that do come out of the laptop battery are all good and a good brand.

[@psedach]

China CAN knock off anything :) I've seen images on forums where people showed a smaller cell inside an 18650 body with the rest of the volume being concrete. So weight isn't even a good indicator...

[@richardlloydusa]

Agreed. Thanks.

[@pmm4177]

I saw a Chinese knockoff El cheapo USB hub with rocks in it lol

[@bobravenscraft5376]

No bro in laptop packs the companies are legit you are thinking about ultrafire these are 100%real deal

[@cadderley100]

Oh, is that all a craptop battery is? I've not seen a battery pack taken apart before.

[@KetansaCreatesArt]

Those LG batteries still have their half or 40% cycles or 2 years of ussage left when you use them as single. Because I have heard that laptop battery packs dont use full capablities of these individual cells. How long did they last for you?

[@richardlloydusa]

+Kketansa Art Still using the ones I harvested from this video. I get 1300 to 1700 Mah from the ones I harvested here. Can't beat the value. Thanks.

[@KetansaCreatesArt]

Richard Lloyd Awesome, I did the same with Vaio battery pack. Running well. I guess even if you get a new batterypack for this purpose, they will still be a good value.

[@richardlloydusa]

+Kketansa Art I have done it and the cells were even better, which is what you would expect. Thanks.

[@pulesjet]

Some lap top batteries use the PIC Processor within them as a Cycle Clock. Dell does or did. They can render the Battery pack dead after so many charge discharge cycles when in fact there is nothing wrong with the batter pack. Harvested batteries can be fine and have quite a bit of life to them.

[@richardlloydusa]

I agree. Thank you for watching, commenting and the kind words. All the best.

[@HBPowerwall]

spent the last 4 months harvesting laptop cells, what a job

[@richardlloydusa]

+HBPowerwall Why were you harvesting cells for 4 months?

[@HBPowerwall]

Just for my own project - and i should have said i've been processing laptop batteries for 4 months. +1300 cells so far :)

[@richardlloydusa]

+HBPowerwall Wow, that's one large project you are working on. Thanks.

[@baileym43ish]

it's three years later now, how did your project turn out? and what was your project?

[@AndreDeLimburger]

How do you open the battery pack? I'm afraid if I use a Dremel I would cut the batteries inside.

[@darrelljenkins9686]

I just watch the video and I have to say thanks for the help I had got some batteries from my neighbor and they were connected together just like the ones on your video and I did the instructions and now I have lights for my bike so thanks again :-)

[@donaldhenke2750]

where didyou get flashlight that will take those batt?

[@DreiGuapo]

I have an old laptop battery pack and it says 3600mah on the back of it. The laptop is a Sony so how much man wouldf be in one battery? (I'm trying to make and sell powerbanks)

[@richardlloydusa]

It's impossible for me to tell you. The battery pack may be in top shape (high storage capacity) or it may be near the end of it's service life (Low storage capacity). The only way to find out is to take the cells out and test them like I did. Thanks.

[@793Junaid]

Good video. My original laptop battery is dead and have these cell specs = ICR 18650 Samsung 30B. So when I replace the dead cells, can I only use the same Samsung 18650 30B cells or they can be any other type e.g. 28 or 32f etc..? Thanks

[@bryanbarnard4094]

It is theoretically possible that the UltraFire's are first-gen Li-Sil which, while having much greater energy density, have massive degradation after only a handful of cycles. Keep in mind that Tesla Motors chose Panasonic 18650's after extensive testing on all 18650's on market, and then some prior to choosing Panasonic for their vehicle. There's a good bet there is a reason why.

[@richardlloydusa]

Bryan Barnard I am still using the batteries I have harvested from this pack and with my Lipro charger have determined that they are 1200 to 1700 mAh and I have no idea what they were originally rated for but they are far better than any 18650 Trustfire, Ultrafire I have and I will never buy another ****Fire battery again. They are all garbage and these are a far better value. I have bought many Panasonic NCR18650B 3400 mAh batteries and they are are amazing. Here are those videos: kzbin.info/aero/PLnxXRLSlmSVO3L0jStRnPEEN2egrODjnm Thanks

[@DMAN22yeah]

+Bryan Barnard panasonic, samsung, and most name brands other than generic chinese brands are guaranteed capacity. if you want a 100% guarantee of capacity use laptop batteries.

[@MahmoudSuhail]

You know what?! THANK YOU A LOT!

[@Toophless1]

Great information. Any idea where to look for the larger TF26650 batteries?

[@richardlloydusa]

I don't believe the 26650 are used in laptop battery packs.

[@recreate3204]

Just took the batteries out of my old HP battery pack and it had 6 of them. I can't find what battery or voltage they are though. It has a number on each battery that I looked up but can't find anything.

[@recreate3204]

Checked them all with a multimeter and they all came out to about 2.5-2.6 volts

[@richardlloydusa]

+Josh J They most likely are an OEM 18650 Lithium cells which usually are rated 3.7V. Get a proper charger to safely charge the cells. Here is the one I use Nitecore IntelliCharger i4 Battery Charger 2nd Gen: amzn.to/1wSEZ8u Here is my video review of it kzbin.info/www/bejne/nl6yhox4iM2gppI Thanks.

[@recreate3204]

+Richard Lloyd Oh okay thanks. I'll probably just recycle them to be honest, they aren't protected and I have a few protected cells already and don't really want to risk anything happening with them.

[@richardlloydusa]

+Josh J You are welcome. Thanks.

[@jessestrum]

hi richard is there a rule of thumb of how many volts above or below i can go with battry cells my cordless is 18v makita and i want to convert to li-ion cells thanks

[@richardlloydusa]

+jessestrum These cells should not be charged above 4.20V per cell batteryuniversity.com/learn/article/charging_lithium_ion_batteries and should not be discharged below 2.7V per cell and it is best not to reach either limit to extend the life of the cells. Thanks.

[@jessestrum]

thanks very much richard great help

[@sammy-pp1gl]

Hi Richard , i have some old battery pack from my laptop . I notice one or two cell have no voltage in it , isupposed this cell have open circuit and not charging any more I have seen some video clips showing how to revive them by pushing the top breaker button to start up again , is it save to follow up ,or other wise, youradvice please nn tks

[@richardlloydusa]

If the cell is at 0 then it's DONE. Do not try to revive it. You can harvest the good cells and throw away the dead cells. Thanks.

[@sammy-pp1gl]

Thanks Pal

[@davidduncan4092]

Most of the fake ones are filled with flour, so weight alone is not a good indication whether or not the battery is real.

[@richardlloydusa]

David Duncan I use my Imax B6 to test them and that tells me how much of a charge they take. They can't fake that out. LOL Here are the videos on that kzbin.info/aero/PLnxXRLSlmSVO3L0jStRnPEEN2egrODjnm Thanks

[@kermets]

im starting to think now that there might be some timing circuit in the laptop battery that stops the battery from being used/recharged but when recovered they seem to work fine...wtf is going on

[@xSlappykinkaidx]

The contact on that third battery was fine, you just put it in backwards. Be careful about that.

[@atomek1000]

dont try to rip this welded tabs form batteries lik this, the cell can be damaged that way(something inside must touch this end of tube to work properly) i did this this way until i noticed this damages them to 0volts...

[@richardlloydusa]

I haven't had that problem doing it this way. Note that I don't pull on them I use the pliers as a leverage point by rolling the tabs. This reduces the amount of lifting on the metal. Thanks.

[@DMAN22yeah]

+atomek1000 just roll the pliers

[@TimmiMontreal]

What do you mean by "unprotected"? no overcharge protection? so you need to keep track of how many minutes/hours they are charging?

[@richardlloydusa]

Unprotected as in there is no protection circuitry in them at all. Your charger needs to have overcharging circuitry in it to keep from overcharging these batteries or they will overcharge. They also have not short circuit protection either so you have to be very careful not to do that. The protection circuitry is built into the battery pack and managed by the laptop. Once you harvest these batteries from the pack all that is gone. Thanks

[@TimmiMontreal]

Richard Lloyd Thanks very much. Can you recommend some KEYWORDS (to search items on ebay or other similar site), for a charger then, that would have good sensing circuitry?

[@richardlloydusa]

***** This is what I use Nitecore IntelliCharger i4 Battery Charger - 2nd Generation I don't use ebay as I have been burned with counterfeit product I bought mine on Amazon amzn.to/1xvkYKw Now that you have mentioned it I will put a review video on my list to do on this charger. Check out the reviews on Amazon too.

[@TimmiMontreal]

Richard Lloyd I live in Canada. amazon.com sells this to USA residents for $17, and amazon.CA sells it to Canadians for $30! I'll be damned before I pay them those prices! So it would be nice to know what keywords to search on, so I can find equivalents and better values. BTW, there are plenty of sellers and affiliates peddling this model on youtube already. I just don't think it's worth that much money for a charger. (it's not a horrific price, but it's not a deal either)

[@richardlloydusa]

***** That's highway robbery even with the exchange rate. I just searched Ebay.ca with "nitecore intellicharger i4 v2" version 2 is the latest and found them for under $20 here www.ebay.ca/itm/NITECORE-Intellicharger-i4-V2-Li-ion-Ni-MH-Ni-Cd-Universal-Battery-Charger-2014-/201245221700?pt=Battery_Chargers&hash=item2edb266344 Feedback is 100% with almost 4000 sales so you should be good. Thanks

[@vivialakelinina5975]

i just broke open my old hp zd8000 pack, they are blue but not marked, can i safely put them in my nitecore charger and use them for vaping kanger nano 60w or joyetech mini 75w both tc?

[@bape9872]

yes but be sure they are rechargeable/charge protected that means u can recharge them without them over charging

[@VyprMoto]

HaramBleach How do I check if They are Protected?

[@VyprMoto]

viviala kelinina I have The Same Problem! But my Vape is a Snow Wolf 200w

[@jeffbowman8265]

Fantastic info man!! Keep up the unique work!

[@richardlloydusa]

Thank you very much. All the best.

[@arrowstheorem1881]

Why are laptop batteries using unprotected cells? Is there 1 protection circuit for all these cells in the laptop lithium pack?

[@richardlloydusa]

+Cosmo John Yes they have one protection and charging circuit. You can see it in the video at the 1:34 mark. Thanks.

[@fatmoeller]

Great video thank you. I was actually fooled by the ultrafire 6800 on ebay. I thought oh man finally a battery that will be surpass my expectations. What a bunch of crap. Used it in a usb charger to charge my phone and it brought it all the way from 50% to 60% before shutting off. I was thinking maybe I did not charge that one so I charge it up was done in no time which I thought was wierd. This time it brought it up 5% before shutting off. Gut out some wire and used my hobby charger to discharge and then fully charge the battery. I had to do it twice because I just could not believe the results. 860 mah yes a whopping 860 mah. I think these are really old batteries they found somewhere and have rewrapped them to read 5000 6000 and 6800mah. These batteries were removed from Amazon due to negative reviews. I have made an official complaint to Ebay but I doubt the greedy company will do anything about it. Any one who reads this please complain also so we can get these garbage batteries out of the US.

[@richardlloydusa]

You are welcome. They are garbage batteries. They are like the "heavy duty" batteries from the dollar store. They look good and then you figure out why they only cost a dollar for two. Ebay is still selling the bogus batteries and some people actually think they are getting good product. If it's your first purchase you would have nothing to compare it to. Thanks for the feed back and watching. I appreciate it.

[@dddd-ci2zm]

This is so true. Every single battery on eBay is fake. The knock off battery packs for the iRobot vacuums are all mislabeled too and only about 1/2 of they claim.

[@richardlloydusa]

dddd If you want "real" batteries understand that there is no 18650 battery which can store more that 3400 mAh so anything claiming over that amount (currently) is a fake. I made some video's on a few 3400 mAh batteries here kzbin.info/aero/PLnxXRLSlmSVO3L0jStRnPEEN2egrODjnm but the are not cheap. The old saying,"If it sounds too good to be true, it probably is." applies to cheap batteries. Thanks.

[@mickoerrolmortega1214]

Is it safe for vape?

[@richardlloydusa]

Check the manufacturers website for further information. Thank you for watching and commenting. I appreciate it greatly. All the best.

[@jakubpomykaa3625]

I know I’m late to the party, but no. It’s not safe for a vape.

[@michaeldean8830]

You have to pay attention to amp limits, These are not for vaping.

[@xSlappykinkaidx]

[@Crimsontide798]

I like to get some 18650 batteries and charger for my flashlight was wondering where you get yours from on the internet I wish I had a laptop battery to get them from but I don't

[@richardlloydusa]

Crimsontide798 Here is a link for this battery pack at Amazon amzn.to/1lDiRrS it's $11.06 and you will get some decent batteries for the price. I tested all the batteries I got out of the pack and I they ranged from 1300 mAh to 1793 mAh and I got six out of the battery pack. Here are all my charging and battery videos kzbin.info/aero/PLnxXRLSlmSVO3L0jStRnPEEN2egrODjnm Thanks

[@Aff3ct000]

Hit a pawn shop or hit up your friends. Literally EVERYONE has old laptops lying around in their basement or storage room. You'd be surprised at how much are just sitting around unused. If the battery has sat for years you may have some dead cells on your hands. Li-on doesn't play nice with full discharges.

[@richardlloydusa]

+@ffec+ Thanks.

[@PeroXepatonio]

Dear Richard do you know the constant discharge and max discharge of these batteries? Or is it possible to direct me towards a site that has that information? BTW this vid helped me salvage the battery pack from my old battery pack of my HP laptop. Great informative video.

[@richardlloydusa]

+Pero Xepatonio It differs from manufacturer to manufacturer and even between different batteries from the same manufacturer. If you can see any printing on the cells you may be able to identify the manufacturer and the cell type as well and go from there. I use a basic RC charger to test these cells but that only tells me the Mah capacity. Here are all my battery videos: kzbin.info/aero/PLnxXRLSlmSVO3L0jStRnPEEN2egrODjnm Thanks.

[@faefdsedf]

I have an old IBM Thinkpad X21 battery. It has 6 red cells inside, they are larger than an AA battery by far. Do you know if I can mod them into a Gameboy Color?

[@richardlloydusa]

I would not recoomend doing that. These batteries are 18650's they run 3.7 volts and the gameboy runs at 3 volts. It might smoke your Game Boy. You would be much better off buying a set of rechargeable AA Ni-MH batteries like these 2000mAh at Amazon: amzn.to/16pWruy or a high capacity 2400mAh AA set :amzn.to/135f70E These will pay for themselves in no time if you use them frequently. BTW you will need a Ni-MH battery charger for these as well. Here is one at Amazon: amzn.to/1ACSMCA

[@faefdsedf]

Yeah, the voltage is not the same. Anyway I'm gonna try to recharge them to see if this X21 battery revives. Thanks for the reply!

[@richardlloydusa]

Faef Lemon You're welcome. Thanks for watching and good luck.

[@saimkhalid9667]

I need a little help i have the same battery as yours and want to replace cells but i read somewhere the replacing cells is in vain because a chip is included in circuit that stores the information of the cells if you change cells the battery doesn't recognize it and show 0 charging and you have to reset the information stored on the chip and it is difficult is it true or i go with replacing the cells... and need some information about the cells my battery is 10.8v 55wh and 4910mah each cell of 1.8v, is it necessary that the voltages of replaced cells should be same as previous or it can be changed and and can mah be changed and is the cells in the laptop batter are simple rechargeable or they are different..

[@richardlloydusa]

I have never tried to repair a battery pack. But here is a detailed article of what that involves batteryuniversity.com/learn/article/how_to_repair_a_laptop_battery Hopefully that helps. Thanks for the question. Looking for the answer helped me learn something new. All the best.

[@gerardvandergraff7031]

That battery is less expensive than buying 6 decent cells to rebuild it. Look at Amazon and they're only about $12.

[@thebwaapbwaap4773]

don't expect much of these cheap battery's, the safety electronics inside mostly suck and you'll get (if you're lucky reused cells) complete knockoff cells that deteriorate amazingly fast. better spend a few bucks and replace with top notch cells

I bought a 4 pack of that knockoff NiMH you display at 8:54 but grey colored. Funnily enough I knew it would be a cheap knockoff (I'm not THAT naive) & only bought them so I could gauge the true capacity which averaged around 350mAh. It definitely felt lighter than the other genuine NiMHs I own.

[@richardlloydusa]

+tombell12 You can tell they are garbage pretty quickly. Thanks.

[@bendari]

Hi Richard, I'm going to order the HP battery pack from Amazon. How hard is it to open the battery pack without a dremel tool? Is the battery pack made of metal or plastic? These batteries are real LG's at least I hope. If you can please reply. Thanks. Mike PS another Fantastic video!

[@richardlloydusa]

Thank you. You don't need a dremel to open them but it's nice to have. I used flat head screwdriver to open my last one. The casing is made of plastic. Just be careful not to damage the cells also understand that the batteries may be charged so you don't want to short them. Work safely. Thanks for watching.

[@bendari]

Thank You Very Much for your prompt reply concerning the HP laptop battery pack. I feel so relieved knowing the battery pack is Plastic and not metal. Should be no problem and I'll be careful not to damage my batteries. Mike

[@richardlloydusa]

bendari You are welcome. The batteries I have harvested from these packs are the best batteries I have for my LED lights. Thanks for watching.

[@jesselam5867]

How do you find the mah on the individual cells with the given information on laptop pack

[@richardlloydusa]

+Jesse Lam Usually there is information printed on the individual cells that help to identify them. As you can see in the video there are six cells in a pack you could take the total mAh advertised and divide by 6 to get the total for each one or you could buy a lipo charger and check them individually once you harvest them. I have a video on that here kzbin.info/www/bejne/roOooWeKZ81-f68 Thanks.

[@jesselam5867]

O well the cells I harvested form a laptop pack did not label any information on it however I found 9 cells and the original laptop pack said the capacity was 85wh. The thing is 85wh may be refering to the capacity at 11.1volts Not the capacity of the cells at 3.7volts so I don't know if it can just directly divide it by 9. Do you know any mathimarical equation for this

[@richardlloydusa]

+Jesse Lam You have to know all the correct values to figure out how much each cell has. Your best bet is to use a LIPRO charger like I did. I recommend Turnigy Smart6 80w 7A Balance Charger with Graph Screen. Here it is at Amazon: amzn.to/1Ur4o8y I can no longer recommend the Imax B6 as there are too many clones out there to be sure you get a real one. Once you have a charger you will be able to reliably charge your cells and at the same time be able to check their capacities. If you are going to be doing this regularly, like I do, it's well worth the investment in the charger. What are you using to charge it currently? Thanks.

[@jesselam5867]

+Richard Lloyd I use the cells for headlights and torches they come with a li ion charger and it outrupts at 4.2volts at 500ma.So it just tells you when its full and when it's charging

[@nestorasuncion1226]

When going to Ewaste centers, and looking which one of those pack to buy, First is to find Manufacturer, whether it's Dell, HP, etc. The one to look for first is Japanese made. Toshiba, Sony, Panasonic etc. because they have Japanese made cells mostly panasonic which are rated better, in capacity and quality. The next is to look for total voltage and total Watts Hour. For the most time the total voltage is 3.7 x 3=11.1 which tells you that there are 3 batteries in series. If the pack looks like there is only 3 batteries in a row, the overall size would be just that, which some of the older laptops used them. Most of the packs are 2cells in parallel(2p) and in series of 3 cells (3s) for a total of 6 cells. the higher and bigger packs are 3 cells in parallel (3p) connected in series (3s). Now is the total Watts of Watthour on the label. The example pack on this video is 47Wh at 11.1v. The total Watthour is the total capacity of all the cells in Parallel, where the total voltage is the total voltage in series. So dividing 11.1/3.7 =3S. From Power equation P=EI where P=Watthour total, E=total voltage and I will be the total Capacity in Amps. 47/11.1=4.234 Amps. Now comes the logical equation, you have a total of 4234milliampshour, this can't possible be only one cell in series, (1P3S) for a total of 3 cells, because from the look of the pack, first of all. Does it look like only 3cells in the pack or 6 or 9 or 12, comparing from 1 single cell. If its only 3 cells, there is not a single laptop battery cell that is more than 3000milliamps. So if you look again at the pack and it looks like 6 cells total, then you have (2P3S) pack so each pair of cells in parallel has a total of 4234mah. Each cell capacity would then most likely be 2117 mah. Its rating would probably the next even number which is 2200 mah. The rating is not necessarily the actual capacity, because of other factors involved as in battery chemistries and their impedance or resistance. The higher the resistance the lower the capacity is from its rated capacity. If you have one of those intelligent chargers, it can tell you the resistance, like the Liitokala 260 or the opus BT-C3100. The common balance chargers does not give you the impedance or resistance values. The more the cells are charged and discharged, the higher the resistance increases. There are some that has 4cells in parrallel and in 3S for a total of 12 total cells. 3.7 x 4 would amount to 14.8v total. I have seen those more common to the bigger laptops with bigger monitors. If you can't find Japanese made packs, the next choice I go for is Dells. They were ahead of everybody in my opinion. Almost all the Dell packs I have dismantled, had a temperature sensor built in and were wired for balanced charging. I guess they made sure the temperature sensors were there to prevent damage to the cells and exploding laptops afterward. Have a happy hunting.

[@charcham666]

how can i know the + and - ? thanks

[@richardlloydusa]

You can see the the positive terminals at the 3:05 point in the video and you can see the negative (ground) at the 3:17 point in the video. If you want to be sure you can use a digital meter like this one Etekcity MSR-R500 Digital Multimeter, Volt Amp Ohm Meter with Diode and Continuity Test at Amazon: amzn.to/2e1Z5Q8 It will tell you the voltage and the polarity. Thanks.

[@fklotaloi]

Uploader Richard, U didn't show th load testing of th cells u salvaged. Those mAh writing is guaranteed since frm a name brand HP. Those cells showing good voltage, bt might be weak or can't keep th charge once u put th load on. Am I write ? :-)

[@rockvillemike6062]

You keep calling them "batteries". They are not "batteries", they are "cells". When they are all connected together, you have a "battery' of "cells". Just sayin' Mike

[@richardlloydusa]

Thank you for watching, commenting and the valuable feedback. I appreciate it greatly. All the best. 👍😀

[@daand12]

I've ordered a Laser + Led Flashlight on China en it may getting home in 2 weeks. I do have a old Acer battery pack which has already the plastic taken off. They batteries are CGR18650CG. Which leads to Panasonic cells. Ordered a Imax charger to for properly charging those lithium cells, instead of the included battery charger with the laser.

[@richardlloydusa]

daand12 Excellent decision. The cheap Chinese chargers are better than not having one but just barely. LOL you will be happier with the Imax B6. I am still using and enjoying mine. Thanks for watching.

[@daand12]

Richard Lloyd dunno if that charger is a clone. It did cost me €23,-. I think it's around 30 dollars. This is without power supply. I heard that 1 amp 12v should work for just 1 lithium cell with 1amp charge current. I do also have another charger that charges nicd, nimh and nizn. It has a 0.9amp charger 12v. Voltage range is between 10~15v for charger. It can charge 4 batteries and 1 amp just fine. My imax b6 is currently at Guangzhou Terminal for flying to the netherlands. Will charge my 18650 from the pack first. I had them at around 2.3-2.4v under 60watt load. Open circuit 3.6v each cell. So it is discharged. edit: i charged those cells using my old laptop where the battery came from. The laptop charges those cells to 4,08v which is not 4,2v it should do. There was already something wrong when the battery was almost full. It will power a 60w bulb for like 30 min or so i think untill it's around 2,5v.

[@richardlloydusa]

daand12 I know mine is a clone but it works just fine so I don't care. LOL I check the end voltages with my meter and they are very close to what is displayed on the charger so I am happy with it. I find that the 2 amp charger I use is OK but not great. I use a 5 amp 15v laptop power supply and it works very well. Thanks.

[@daand12]

Richard Lloyd You think that a 19v 3,42a will work ? It's 19v x 3,42a = 64,98W of power. As i said earlier, a 0.9a 12v psu will charge 4 nimh batteries @1amp each just fine. So i guess the B6 won't give me problems either with a 1.5amp 12v psu.

[@richardlloydusa]

daand12 I think you mean 19V X 3.42 A = 64.98W . My PSU is 15V X 5 A = 75 W. Yours should work fine. You can find 5 Amp laptop battery PSU's for under $10 on Amazon amzn.to/1BOJU2m

[@MediaMocker]

id recommend leaving the tabs on these, just snap them. as u can see it leaves little holes if you do :)

[@richardlloydusa]

MediaMocker I just used my Dremel tool to sand the tops smooth. These tabs are sharp if you leave them on. My preference is to take them off but it's up to you. BTW sandpaper will work fine as well. Thanks.

[@MediaMocker]

Richard Lloyd I only mentioned it as lithium becomes volatile once exposed to hair. I had a cell vent after a few days when tearing off tabs. So its a lot better to smooth the tab down than yank it out :p "Exposed lithium can react with water or moisture in the air causing potential thermal burns or fire"

[@richardlloydusa]

MediaMocker Good safety tip. Fortunately the casings on my batteries were tougher than the tabs so the holes occurred in the tabs. Unfortunately the only way to find out which one will win is to peel them off at which point if the tab wins it's too late. Thanks again for the tip and watching.

[@Aff3ct000]

+Richard Lloyd They were commercial batteries to begin with, THEN the tabs wrte lightly spot welded on. I could see keeping the tabs in place causing damage in your devices due to the additional battery height. great video. I've got a handful of high quality batteries from years past that should net some quality 18650 cells. Remember that tool batteries also contain quality cells. Eg. the DeWalt 20v batteries.

[@richardlloydusa]

+@ffec+ Thanks.

[@VyprMoto]

So I Have (18650) Batteries from My Laptop Battery, I Don't know the Volts Or MaH, Please Help. I also Have a 18650 3.7v 2500Mah battery that was In My Mod "Vape". Do you know what that PC Battery Could Be? My PC Is HP laptop 15-f059wm. Please help

[@richardlloydusa]

Usually it's printed on the cell it's self. If it is not the only way to find out is to fully charge the cell in a charger like Nitecore Intellicharger I4 At Amazon: amzn.to/2geIU2U then do a discharge test with an Imax B6 balance charger at Amazon: amzn.to/2fE4LfT . This is the only way I know to do it. Thanks.

[@GhostvaperYT]

HI vYPRmOTO i CAN HELP YOU if you tell me what is written on the batteries? any ID numbers? i'm also doing this for vaping. lol

[@JohnDoe-gm5qr]

I have a laptop that uses that part number. It looks as if there night be 6 18650s inside it. It is one of those ones that no longer holds a charge. I have read that it only takes one bad cell to cause them not to work and usually most of the cells are good. It seems to me that the protection circuits inside a battery pack won't let any cells take a charge if just one is bad. I know the individual cells are not protected but there is a board inside each most laptop battery. Any laptop battery that is not known for starting fires would likely have that circuit. It is better to have a battery that does not work than a house burned down or a someone badly burned. Also you would not want to inhale any of the fumes if one of those cells does leak or vent. It smells horrible and it is certainly not good for you what it is. I read that hydrogen flouride is one of .the gasses released. I do not know that for sure but hydrogen flouride is very nasty. It is also known as hydroflouric acid which dissolves glass. There are a bunch of other nasty acids that don't affect glass like that. Hydroflouric acid is stored in containers made specifically for it because it will dissolve things many acids don't even leave a mark on.

[@richardlloydusa]

I would take the pack apart and test the batteries individually to see which one is bad. Even if they one is bad may hold enough of a charge to use in a flash light. You never know but at this point you have nothing to lose. I took a cheap "protected" Chinese battery apart here: kzbin.info/www/bejne/fGObqHqkeappg9U and yes the smell was terrible. Even though it said it was a protected cell it actually was not protected.

[@JohnDoe-gm5qr]

Richard Lloyd I have an Ultrafire 4000 mAh that said protected. It had no PCB on the bottom. I also would not believe the 4000 mAh claims either unless it was a 26650 cell instead or somewhat bigger than 18650. I also have a couple NiZn batteries. Those are nickel zinc. I never had such a crappy battery in my life and I once use nickel cadmium batteries that also suck.

[@DMAN22yeah]

+John Doe pcbs are usually on top, and they usually are fake, i have some 4000mah ultrafires, extremely light and have a short circut current of 14 amps, definitely not protected.

[@ColtonBlumhagen]

Buying 18650s standalone is for suckers given the insane prices! When you consider that most people probably have some old crappy laptop battery lying around their house.

[@richardlloydusa]

+Colton Blumhagen I depends on your application. If you are on a tactical team and need reliable long life performance the standalone cells guaranty performance and in a life or death situation I would think they are worth it but for everyday use these can not be beat. Thanks.

[@bobravenscraft5376]

They are valid mine were 2200 on the money new 15$ eBay these old ones shot flashlight food

[@richardlloydusa]

They are legitimate cells. Thank you for watching, commenting and the valuable feedback. I appreciate it greatly. All the best. 👍😀

[@Rmathis80]

You could put one in a mechanical mod and vape with them...

[@richardlloydusa]

As long as the mod can take an unprotected cell, you are good to go.

[@DMAN22yeah]

+R Mathis as long as you dont exceed 1c continuous or 2c peak

[@opensourceftw3282]

[@zakrache8887]

hi.How can i refill an old laptop battery without inserting it in the laptop ...or incase the its laptop is already dead ? thank you..

[@richardlloydusa]

I would not recommend it unless you know all the specifications of the battery pack you are trying to recharge manually. You would need to know all the pin outs, voltages and amperage values to do it correctly and there is too much room for error in my opinion so I can not recommend that you do it. Be safe. Thanks.

[@taunteratwill1787]

Nowadays this test is shit because the chinese have caught on to it, if need be they fill their 18650's with leadpellets in glue to get to the desired 44-46 grams. The only way to be safe or sure is to go to your local dealer and buy Samsung, Lg, Eneloop, Panasonic or Sony. It's more expensive but they work and are a lot more durable. There are no 18650 lithiums above 4000 mAh! So he's right to highly doubt that! LOL. The chinese even have replaced chips in the protected ones wich state after testing a very high current, just give them a try and be dissapointed. Even buying the more expensive batteries in Shenzen China (AliExpress and the likes) will not guarantee that you get the right stuff. I learned the hard way. Don't buy batteries in China. Btw The likes of R-Trippers or Indoor-Smokers which i for various reasons regard as commercial whores. Have this problem, you don't bite the hand that's feeding you!

[@133Djdude]

oooo maybe i can use these in a mod i doubt it would be safe though

[@richardlloydusa]

Please note that they are unprotected battery cells before you use them on anything. Thanks.

[@richardlloydusa]

jacker372 Bonus for you. Be sure you are careful with these batteries as they are not protected against shorting, over charging or under charging. Understand that these are powerful batteries that need to be handled safely an properly. Thanks and good luck.

[@jacker372]

Richard Lloyd well I ordered 3 of those 1a lipo chargers and I'm gonna make 3 batteries and hook all of them in parallel with diodes between them. Then use 2.9a worth of solar panels go charge it all

[@richardlloydusa]

jacker372 Cool enough. Tell us how it worked out for us please. I am curious. Thanks.

[@jacker372]

[@richardlloydusa]

[@sparksilence]

Can you recoomend a safe charger for these and where to buy it ? Thanks.

[@richardlloydusa]

I use the 2014 Version NITECORE i4 Intellicharge Battery Charger here it is at Amazon: amzn.to/2dyGY1R It works great for me. Thanks.

[@JasonWW2000]

A smart charger might be more useful since they can measure actual capacity. It will tell you the mah of the battery. I use the xtar vc4 for about $30.

[@richardlloydusa]

Looks like a cool charger but seems to be limited to a 5V input only, which is ok but for travel charging with 12v systems may be a hassle. I also so in the reviews that it is limited on output to .5 amps depending on how you populate the bays. But again if you know it's limitations I am sure it will do a fine job for you. Thanks and all the best.

[@JasonWW2000]

A 5 volt input means USB. You can plug it into any USB wall or car charger. So it's actually very flexible. When used with a 2 amp USB charger it can charge 2 batteries at 1 amp each or 1 to 4 batteries at 0.5 amps each. It will also charge NiMH batteries up to D size. I've used the capacity measuring abilities on some old batteries to see how good they are, that's handy. Mainly it's got a nice display compared to Nitecore. Both brands work well, but the VC4 is about double the cost at $30. Ideally, you should write down what you need. Lithium only or lithium and NiMH charging? Fast 2 amp charging or will 1 amp or even 0.5 amp be fine? Will you need to charge big D sized 32650 batteries? Do you want a voltage display? Etc... Then look at the nitecore, xtar, and other websites to narrow down your choices.

[@richardlloydusa]

Thanks for the great feedback on this. It does look like a good charger. All the best.

[@SpecialVeloce]

Great vid, thanx for that. Actually think to exchange the cells from my laptop pack. Really you get what you pay for chinese battery case. Cheers

[@richardlloydusa]

You're welcome. I am going to upload a video where I compare these with the Ultrafire batteries next. Thanks

[@JohnDoe-gm5qr]

Everyone says that the Chinese batteries are dangerous and to only buy good Japanese ones instead.

[@richardlloydusa]

John Doe It's hit and miss with the Chinese batteries but mostly miss. Here is a video on their capacity claims vs the real capacity of the batteries. Note that the Thunderbolt made in China NiMH rechargeable batteries were actually better than they were claiming. kzbin.info/www/bejne/roOooWeKZ81-f68

[@jonathanli6955]

I harvested 18650 too but they all come in at 7.2 volts on a multimeter #wtf??????

[@richardlloydusa]

+crisis corral Disconnect the leads that go to the ends of the batteries first make sure they don't short circuit and you should be fine. Be safe and be careful. Thanks.

+Richard Lloyd -Red positive first then black neg then the ?ground -in that order? BTW it is from a Toshiba and has 12 light blue bats -hope they're good

[@richardlloydusa]

+crisis corral Just take your time and be careful not to short anything and you should be fine. I am sure the majority of the cells will be fine. Thanks.

[@DMAN22yeah]

+crisis corral take off the label sticker, use a screwdriver to lift up the side of the plastic and pry it up with pliers, it should pop the plastic piece off and then you can safely and easily remove them. dont worry too much about damaging them though, they are in a metal case. if you do rip the insulating part use packing tape to fix.
