[@tiggywinkle1000]

My 20 years+ old Bosch drill/driver's battery (NiCd) packed up. I sawed off the base of the pack and found 6 cells inside, wired in series. Removed them with side cutters, making a drawing of where they went, polarity, etc. Ordered 6 modern NiMH cells (Batteriesplus), with twice the Ah capacity and higher current capability (more power). They arrived fully charged in 48 hours. Soldered them all back into the case (the cells have solder tags) and fastened them with the hot melt glue gun. Then glued the base back with Superglue, and painted over the cut to conceal the repair. The old charger works fine with the new battery, you just have to time the charge using NiMH, and not leave it on permanently. The repair saved me over £50, and my old Bosch drill works better than new with its upgrade!

[@frugalprepper]

yeah replacing the cells, especially with NiMh is better for sure.

[@GamingKeenBeaner]

If you continue to do this, you would really benefit from putting some wire leads on the battery so that you arc against the wire ends and not directly against the contacts.

[@haroldkline4898]

Thanks a lot dude! I don't have a welder, but I was able to get them working again using a car battery (in parallel) that puts out about 2700 Watts. They went from reading flat zeros to about 7 volts and now are taking a charge. Great tip!

[@stinkycheese804]

You don't even need a massive battery or welder. A plain old 12VDC wall wart, or laptop power brick, etc (though you need current limiting resistor to keep the PSU running if it's a regulated type with an undervoltage shutdown protection circuit) connected to a good sized capacitor bank will allow zapping with plenty of current to burn through the dendrites shorting out the cell. Obviously not everyone has a "good sized capacitor bank" lying around (lol) but if you're going to go the route of zapping cells, then realize that you're going to have to keep doing it and it may be worth the bother to make a capacitor bank to do so, so you aren't trudging out to where a car battery is every time. Then again a sane person would just buy a new battery.

[@braeburn2333]

Ive done this but i used two good tool batteries wired in series to form a 36 V cell. I used that to zap the bad batteries instead of a welder. It worked well.

It's the high voltage pulse that knocks those whiskers off, the bendini magnet motor design does same thing and can help restore batteries the same way.

[@user-yq2wk6yg8s]

The thing I like about this video is it shows the reality of a fixer's life. Nothing ever goes right all the time, or at least not for long. So he's in the middle of filming and the multimeter starts playing up. That's so real. One out of three of the batteries is a failure but you can't resist giving it one more try. Great job, Frugal!

[@johnmilner7603]

Hitting it with a stick or mig welder will usually make the Charger see the batt as chargeable but once the Charger completes the charge, the drill will not last long on that charge. I tried this with my Milwaukee 12V. My fix was to buy a new 12V pack.

[@Jamespennington71]

I tried this with just a pair of 12v car batteries and some jumper cables to make 24v and holy crap it worked! I had six old Ryobi ni-cads that hadn't charged in at least 10 years but I kept them hoping I'd find a tip like this. Thanks man!

[@johnbrown4897]

After seeing this I tried it on my 3 18v dewalt 100% flat batterys which has been in my store room unused for 6 years I used my battery charger on 24v with full 30 amp out put to spike the dead batteries 6 times each and to my surprise all 3 recharged on the dewalt charger and are working fine.

Do you think a quick jokt of 110 volts would be too much?

[@toddsmith1976]

WAIT, STOP, NO THATS BAD! Don't use an A/C power source if that's what you mean. The chances of having an explosion will be far greater. Its like trying to jump your dead car battery off from your neighbors running car backwards. Instead of negative to negative and positive to positive, you either have a brain fart or you just made a one time careless mistake and hook it up backwards. It will probably internally fry or explode both batteries, spraying battery acid onto every piece of uncovered skin on yours and everone else in the areas entire body, damage both cars entire electrical system, including the ECU, otherwise known as the vehicles electronic brains, $$$. You don't ever want jump a battery off without a full respect for every step of the procedure. If you accidentally or otherwise use alternating current, or in other words, the power that comes out of your home's wall outlets, in this already highly risky little hack, it will probably least of all do permanent or irreversable damage to an otherwise salvageable battery pack. It has the potiential to take your freakin face all the way off, and probably burn your house down too, and just radiating collateral damage from there. There are no words to describe this god awful blood bath nightmare. There is just no way to even begin to really imagine the horrible consequences and regret. It has happened many many times before, and will continue to happen to many many more in the future. The danger is super real. This hack, working with batteries, or working with electronic and electricity period requires training, and an understanding, and the respect on a level that most will never know anything about for the life and death dangers involved. Saftey has to never be neglected, because something will happen eventually to even the safest and best professionals and practioners in the business. So please, do not even attemp this without having a good working knowledge of basic electricity. Ask someone to help you do this if you don't have total confidence in your knowledge and abilities. Frugal prepper says more than a few times that even under the best circumstances, there is a real possibility for things to really bad, really quick. That is real talk my friend. I speak from practical experience. 3 years college to be a federally certified aircraft mechanic, A&P certified. I maintained 5.0 GPA every time from day one to graduation. I graduated valedictorian, I had extensive studies in electronics and electricity, and I've got over ten years expeience on the job as a licensed professional specializing in electronics and electrical systems. I have seen some accidents on the job. And I have seen people lose theIr lives while at work doing the same thing that I had been doing all week. I don't talk about it. I only say now because I can't overstress how the danger we're looking at here is the very same seriousness. When I consider the people that I respect and that are an inspiration to me because of there knowledge and level of expertise, I can easily admit that in contrast between them and myself, I am like a baby that don't know jack. I have had the privilage of working with and learning from some amazing people. Not many, but some, very few would I actually say really they do have that broad and solid understanding of the craft and can manipulation electro-mechanical energy that our modern state of the art technology is baised on. It is more like devine magic than scientific fact. There are many aspects of it that the human race still doesn't understand. Even some basic things such as fundanental laws. Even Tesla almost electricuted himself to death at least once. hat anything else I know of. not everything by a long shoot, but far more than the other 98% percent of those in this feild, what electo-machanical energy. Be cautious and us descretion when duplicating DIY projects seen all over youtube. But going on with this refresh hack, I'm not positive what Frugal said about the voltage he was using in the video for sure without going back, I think those small welders usually run around 17 volts DC. Therorically you want to swap his current value over to your volts because that value is around 100. I think you said 110volt to be exact. Likewise, his volts value will now be your current or amperage value. So, you will use something like 110 volts DC power source with a maximum current output value of 17amps. The value of the Voltage and current variations are directly related when the intention is to maintain the same power output. In this instsnce, because our load or what ever you applying this power to, the battery to be refreshed, is the same either way. When the load is changed things get alot more complicated. The load or resistance in a curcuit also directly affects the power consumption in a electrical curcuit. If all you want to do is revive a battery pack that is similar to what Mr. Frugal shows, then that is why the we can just swap these two major values and still come out with the same end result in essentially an identical way. The fact that the voltage is much higher makes no differece because you are also now using far less current. Same, same. You understand? The current is reduced according to it's relation to the increased voltage you are using. The 110 volts DC that you proposed is actually the easy conversion to calculate bucause you actually just swap those values and you will still be acheiving the same rusulting output or total energy or power. It is the energy being expended by that spark you see when you make contact with the positive and negative terminals of your battery you want to refresh with the positive and negative wires of your power supply you are useing if thats easier to understand in simple terms. It's measured in watts or joules. In addition you must further consider that Frugal says that he is used his power supply turned down to the low setting. By setting it to low power, the current is probably being limited to some reduced value while the voltage remains constant and unchanged. Maybe he can elaborate on some of the questions about his specifics in another comment or follow up vid. If I were to attempt this. And I still really don't know if I would. At least in the same manner as shown. I would gave to make it a little safer by doning it remotely with some shielding. Expect an explosion and try to at least make it a controled explosion with saftey measures in place. It's the same as Russian Rullet in every way the way we saw in the video. I like it. It's really smart. I didn't know it could be done, but Mr. Frugal seems to be a pretty sharp fellow and knows the facts about the things that he is talking about. There is alot to he said for that. Especially with all the ignorance that's going around on youtube. I learned a valuable trick here, but I would leave much less to chance. Another thing too as kind of after thought but deffinatly worth mentioning. All those batteries have a little currcuit board inside them that should probably be removed before you try to zap it. It is the battery charge management curcuit. You need that to function properly in order for your charger to begin and end the charging process after you have refreshed them and I suspect that frugal prepper may have damaged the one inside his battery pack that he nevr could get to start charging. Have fun learning by experimenting on your own. When we stop learning we stop living. Be safe and enjoy!

[@johnchristianhelmfelt8227]

In my experience as I have worked with Ni-CD and Ni-Fe batteries, I have found that discharging the Ni-Cd below 1 Volt they will short circuit to a greater or lesser degree depending on the current, to eliminate the short safely I first tried 4700 uF x 35 volt capacitor discharged into each cell that was shorted generally it did not work as that value capacitor did not have enough energy stored to vaporize the short and low voltage can not force enough amperage through the higher resistance shorts, so I tried next a 4700 uF x 75 volt capacitor with better results, though I still was not enough to vaporize the low resistance shorts, so I went to use a 10.000 uF x 100 volt capacitor, this one was nearly perfect and to get better results I would recommend not to use a single capacitor but o use a bank of capacitors as some capacitor discharge welders have; it is not a good idea to make the discharge through the full battery pack as each cell has its own internal resistance that will reduce the current available to vaporize the short in the shorted cell.

[@1001awab]

Lots of talking. I had 2 flat batteries. No possibility to charge. Drill didn't worked at all. Connected 2 12 volt bat to make 24 volt. Connected the ryobi 18 volt for approx 10 seconds. They worked again. Showed 19 volt and they charging again. Much easier and save.

Great idea -- a pair of welding gloves and a motorcycle helmet with a full face shield might also be prudent at any time you're playing with potentially explosive materials, or maybe set the battery on a blasting cabinet during that procedure.

I wonder - seems like I've read about some of these battery packs having a small thermistor inside as a heat or overload protection. Perhaps that one battery pack that wouldn't take a charge has blown out that thermistor.

You won't have the protection but the battery pack may be usable again for a long time.

Thanks for the tidbit of info regarding how the ni-cad's flow electrons creating the power to run the tool. The satellite reference was more info that I now have stored up in my noodle. I have 7-19.2 Craftsman battery's. Two I purchased online just to have a couple that would take a charge while I tried to figure out how to possibly. I don't have a welder so could I just remove the female repair end that I already have replaced on the extension cord (which is 12ga btw) and use that to try and jump them with 120V at 15 or 20 amps?? I had to retire from the building trades due to health issues so I don't use my screw guns very often but I don't know if this is true for the new batteries that are sold with cordless tools now but when I was working outdoor basically everyday the cold is a stone cold battery killer. If you don't keep your batteries in the house during the night and try to keep them somewhat warmer like on the truck dashboard in the sun or if the house is heated you can put them inside where you are working. I don't know if this theory of mine is actual fact so correct my ignorance if needed, but I found that if you plug a cold charger into an outlet and put a 15-30 degrees F basically frozen battery pack on to charge it kills ni-cad's. Also I found that if you turn on your flashlight and forget it's on and let the battery run all the way out it will give you the defective battery light. I read somewhere that if it doesn't have a certain minimum amount of charge left on the battery it's done. Well it I lost them for different reasons but that is why I have 5 dead soldiers sitting here on my workbench that I hope to revive. One of the batteries I bought online is already dying way too early and it doesn't have the same power that the other one does. And no I haven't kept them in the house because after the back injury I did a couple of rounds with the rotten ass cheap shot bastard that is Cancer. We found it luckily before it had spread (well they think so anyway). My doctor said "Oh, I wouldn't worry about it, 99% of time it's nothing. Well guess who is the 1 percenter!!! When they tell you that you have cancer it is the biggest mind Fuck that I hope I never have to face again. I didn't get out of bed until the evening of the 3rd day. My wife said she was gonna give me about another 45 minutes and she was coming in to the bedroom and kicking my ass. You gotta love her......... we will be married for 28 years in June. I have put her through hell with my bi-polar craziness. "She is the light that chases away the dark"... that is where my demons wait for me to slip off the edge so they can drag me in and then the fight is really on!!! The brain is really amazing. The bi-polar didn't hit me until I was about 48 years old when I had my mid-life crisis. I saw the light of the tunnel I was in go out and the light in a little short tunnel turned on. I am 55 and right now I am coming up on the date my father died. Scary, 55 years old. We played music like always from 6pm until 2am and a family friend found him at 8am that next morning. Sometime after I left him at 2:30am he passed away. Sitting right where I left him. Luckily I told him I loved him like every night and I got "Luv-ya too babe" reply.......... that was it........... I apologize for the length of the post.... I got to ramblin on and on....... happens when I am "manic" which if part of the bi-polar deal. Imagine your brain is running at 10 or so times faster than your normal pace and for me I was a contractor so I am drawing blue prints for something I want to build but I am also thinking of 5 other things at the same time. I will usually go a couple of nights without sleeping. Cannot shut the brain off to relax and sleep.... it's actually pretty awful. So I haven't slept since Friday night so hopefully I will be just exhausted from the non-stop 125 mph that I am running at all day and sleep tonight Peace

Great tip but even besides that is that the way you described how it works and what to do to fix it is one of the most informative methods I've ever came across. Now I knew all this all ready but was curious to watch and maybe it's just me and the way you described it paints a perfect picture and so easly understandable that if I never even touched a battery I'd feel though I'd be able to fix my batteries if need be.

It would have been nice for you to show us the one you did get working was first not working prior to you regenerating it. Question will this procedure work on the 18 volt Dewalt batteries. Was the welder on AC or DC setting and what was the voltage setting and the AMP load did you hit the batteries with.

[@frugalprepper]

That was my intention, but I goofed up while videoing it. I never expected this video to be very popular or I would have made sure I did it again with another bad battery. Yes it will work on any NiCad battery as long as it doesn't have any circutry inside of it, for regulation, temperature sensing, or charge indicators on battery. I am repairing a Bewalt 18V right now for a friend that has 2 bad cells and it has no internal circuitry, but I don't know if there is more than one type of model of Dewalt 18V nicad battery.

I knew when you started talking about satellite batteries you had some very specific expertise, this is a great technique, you can isolated the failed cell/cells in the pack on the ones this doesn't work on, great video

[@thomaskelly296]

I've been doing this for quite a long time. I've done it with coin cells, alkaline cells, Ni-Cad cells, and zinc carbon cells. It seems to work best with Ni-Cad cells. I had a coin cell EXPLODE once. The danger is if you apply power for too long, the cells/battery will get HOT. If it gets hot enough inside the cells, the pressure inside the cell will get so high that they can EXPLODE. My Process: 1) Try to charge. 2) Measure individual cells voltage with DMM on dc range. 3) Those that measure anything close to what they should (1.2 vdc for Ni-Cad cells) will likely take a charge. 4) Those that are zero volts dc are most likely the "bad" cells. 5) Next I measure the "bad" cells DMM on low ohms range. 6) Most likely they will be shorted and measure close to zero ohms. 7) I zap the shorted cells with a high current DC voltage close to the normal voltage of the cell. Be sure to connect observe correct polarity (plus to plus and minus to minus). 8) Wait a bit before continuing (feel if cell is getting HOT). You do not want cells to EXPLODE. 9) I repeat steps 2-8 until cell no longer measure zero volts across the cell. 10 Go on to next cell. The best voltage source is a high current DC power supply that allows you to adjust the voltage and current limits for the output. Next best are variable low voltage welders and 6/12/24 volt car battery chargers.

[@Cagmito125sportsbikespares]

would just charging it with a low current at 19v charge them , using a charger without the circuitry in it obviously ? say using lab power supply at 18v @~ 0.1a current for a few hours or does it need to be shocked ?

[@careyfox538]

Hey Frug, What else can you use besides a welder to get that power surge on the battery? Thanks.

[@frugalprepper]

Anything around 24-30 or so volts should do it. Two car batteries hooked in series would do it.

[@jpblitz2104]

What about two wires directly connected to a 110v socket? Can this surge type be AC or it has to be only DC?

[@sswiths5328]

Mine worked, not right away, you have to leave it in the charger a little longer.. I had to leave them in 3 min to 5 min then they starting to charge.. I did not use the welder, I used wires from one good battery to the bad one, zap it a few times. Worked for me.

[@frugalprepper]

Thanks. Glad you got it working

[@Blissterd1]

Most 110v stick welders put out AC current. Do you have a DC welder? You also said car batteries in series work and they are for sure at DC. I have used high voltage (around 90 v) electrolytic capacitors and discharged them into smaller nicads to de-whisker them but I have some Dewalt 18v batteries that need it and my capacitor trick won't work. Short of rectifying my welder I am short on knowing what to do.

[@frugalprepper]

It doesn't matter if it is AC or DC as long as you get a jolt of voltage to blow the whiskers off the annode and cathode. If you have good 18V batteries you could hook two or three of them in series to blow the whiskers off of the bad one.

[@bobbysolo5411]

Since every welder I have used is very adjustable, it would be nice to know the setting he was using, so we don't go hog wild and hit it with ten times the amount he used, with catastrophic effect.

[@bernhardnizynski4403]

What is the output voltage of the welder - I don not have a welder? WRT the welding rod connection, if you attached a copper wire to the battery terminal and then touched the wire with the welder terminal, you would not have to clean the battery terminal as the copper wire itself would take the welder spark - just a suggestion! Well done, however, very useful information.

[@frugalprepper]

I don't know exactly I am guessing around 30 volts or so, which is what most welder are. It has not setting just a 15 amp and 20 amp switch. It's just a little cheap 120V stick welder.

why not clamp some heavy gauge wire over the terminals and make all the sparks well away from the battery at the welder side or by bumping the AC power feeding the welder. no burnt battery terminals and you could place it under a heavy shield away form you, just in case.

They both took a charge and they were bought in the 90's. I have the 18volt Ryobi now that is getting to where not lasting as long as first did, but I have had them since around 2004.

Nickel cadmium batteries do not have or need microprocessors. The microprocessor is found in lithium ion battery packs to monitor and shut the discharge down at a given volt level. If you don't know something don't speculate. You're teaching people who don't know better a non truth. Be responsible with your words.And picking the battery pack up and dropping it repeatedly is annoying.Learn to get to the important subject matter faster. No one has time to waste because you want to blab for 5 mins and say nothing.

Well said Ola K & Bruce Peck, I mean well written/typed. I’d hate for Jon Jonson to attempt to publicly humiliate me as well by ridiculing either my misuse of vocabulary or grammar... Jon, if you’re as versed in batteries as you claim to be then why watch informative videos explaining anything concerning batteries ???? I’m going to guess either because you’re not as “in the know” as you’d like everyone to believe & or you watch them in hopes that you catch some insignificant trivial mistake that you can rub their nose in. I can only imagine how sad and lonely you must be. Try not to speak to and or treat others in the same manner in your day to day life and I’m sure things will get better for you. Either way I truly appreciate the info I learned from watching this video. I’m sure that after I resurrect one or two batteries It’ll become like second nature to me (I hope). Thank you Frugal Prepper’s Garage & Garden!! Keep doing what you’re doing, which is helping us out with info that we’d otherwise have to pay for or just go without.

[@teddahrable]

Jon Jonson, I've watched people on KZbin present subjects in various formats. Some of them I like, others, not so much. If I watch something I think is wrong, because I consider myself a SME, I don't attack. I just don't watch their videos anymore or recommend them. It's difficult to criticize what someone is presenting when I don't have my own videos to back up my claims. Perhaps, that's way you should do. Grab a hundred different Ni-Cad tool batteries, tear them all apart on you video and PROVE TO THE WORLD that there's no circuitry or processors in them! Or, you could shut up and move on. Just sayin'. And, for the record, I have the same 24 hours in a day that you do, and I didn't mind the 6 minute preamble. Not everyone out there has studied this or taken these battery packs apart. You have a fast forward on your controls, or maybe you didn't know that since it would take previous time to find it and hit that button.

Short question how many Amps of current for the Joilt? And I understand thats a dc welder your using You take 120 volts AC convert it to 120 volts dc current at ?? Amp setting with a 6011 rod no doubt and Jolt the battery for a flash second. I might try this with my 240 volt stick welder set at its lowest setting on dewalt batteries, but you can fully discharge them with Led bulbs over weeks and then get them to work again sometimes. I'm not sure if the XRP batteries have a circuit board in them but at this point what do I have to lose they don't hold a charge anymore. And Dewalt decided to stop making any of them. Lithium Ion go dead with time the chemicals stop working even if you not using the battery, its a bad investment for someone to buy that type if they just use the tool once and awhile.

That't a really good idea!

[@clearmist1]

The chargers have a voltage reader in them because the batteries need to fall within a certain range to begin the charging process. If the battery is too low the charger cannot risk overcharging a foreign battery and risk causing a fire or explosion because the operator put in a battery not designed to be in the charger. So it will refuse to charge. What he is doing with the welder is putting just enough voltage in the battery to get it to the minimum charge voltage so the charger can recognize it as the correct battery type for the particular charger. You could do this a bit safer by using the same battery types so DeWalt to DeWalt one fully charged and the broken battery connecting positive to positive and negative to negative leads, in 20 to 30-second intervals until the broken one can be recognized by the charger.

[@frugalprepper]

It is true that there is a minimum voltage at which the charger will start to charge the battery. It is also current limited and it checks the internal resistance of the battery. It is true the voltage is low. It is true that I am bringing up the surface voltage when I shock it. It is also true that I am blowing the dendrites out between the anode and cathode in the cells which is what cause the voltage to get so low. See this document form NASA about the process: ntrs.nasa.gov/search.jsp?R=19850023073.

The welder isn't charging the battery, it is blowing the dendrites off between the anode and cathode. A welder will put out around 25-30 volts but it is the current that is important for this application.

[@mrgcav]

This is a sure way to blow the internal thermal fuse. You theory is correct but you method requires to do each cell one by one inside the pack at 2.5V @ 2.0Amps. Using a welder or car battery will at least ruin the battery life and possible risk of the cel exploding. You need to provide a gentle shock.
