Battery Type Comparison || Lead Acid VS NiMH VS Li-Ion VS LiPo

[@IncroyablesExperiences]

If the test would have been conducted with a 1C discharge rate, the LiPo would have been the incontestable winner because of it's low internal resistance. What more, after years, the internal resistance of lithium batterie do not increase as much as other technologies. For those two reasons, after a while, the winner in each categories (even the price) is the LiPo for a high power device as an eBike :) Nice video, usefull informations !

Making use of the kzbin.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

[@Hemewl]

You might also want to consider operational temperature for charging and discharging. For instance, in an outdoor installation in cold weather a NiMH will probably win at all times.

[@justtoaskthequestion1422]

I had it in mind for a long time but I was wondering is it actually safe/recommended to run electricity through a permament magnet? I couldn't find anything about anyone even attempting to do so on the internet so I figured there is some issue I am not aware of (and that is probably too obvious to even mention it), hence noneones uses it this way and was the reason why I couldn't find anything. Could someone shed some light?

[@userPrehistoricman]

I think the magnets have a moderate 0.5-2 ohm resistance which makes them okay for charging small batteries

[@cucumber1389]

This was the exact video I needed for assurance on my NiMH battery, thanks a lot

[@georgegibson707]

Battery life (charge cycles), Rate of self discharge, Charge efficiency (energy in vs out)can be factors in the choice too.

[@krzysiekzdrojewski6865]

Yeah, maybe

[@antkoos]

how can you measure the charge efficiency?

[@Trakkson]

@@antkoos Congrats bro, you just dug out 3yo comment. Anyway, you can just measure energy "pumped" into the cell when charging, then measure te energy sucked out of it and compare the two.

[@levelup1279]

They all work forever, just repair it if it breaks then you have infinite charges

[@1224chrisng]

In terms of charge cycles, Lead Acid is weird in that there are 2 types of batteries with different ratings. "Deep Cycle" batteries are made from solid pieces of lead and can be fully charged and discharged many times, whereas "Starting Lighting and Ignition" batteries are made of lead sponge and can degrade rapidly if fully discharged

[@LazerLord10]

Li-Po is great for high-power discharge!

[@LazerLord10]

***** yup. Sounds about right. There's also Li-Fe (lithium Iron), which is pretty low power (mine is 2A max).

[@CAv-lp2qk]

+kingknut icr, inr, imr all meaningless really, as no standardisation amongst all manufacturers in this regard. High discharge "li-po" in an 18650 package are being called "Ii-ion", and low discharge "li-ion" in a soft pouch is still "li-ion".. Go figure!!

[@LazerLord10]

***** Well, they're good for RC transmitters because they're low power, and don't need to be set at a storage voltage. Like all batteries, they're fit for a specific purpose.

[@CAv-lp2qk]

Unless their from certain online hobby store... Their cheaper transmitter packs have been known to puff when left charged.. Probably reject cells rebranded, might have a tiny bit of iron in the recipe so marketing calls em "li-fe".. ni-mh Eneloops are great for tx's

[@profsacin]

Good review. High discharge current is also important.

[@jamesslick4790]

[@Slava-om1sz]

That was great, but I was hoping to so find out more differences in how these technologies behave. For example discharging while not in use, capactity decrease over time and after X amount of recharge cycles, etc.

[@wahidasad4853]

Well for that i may not be so right but once i charged my diy lithium ion battery fan and I don't know how i lost it .but after one and a half month i found it and it gave me pretty much the same backup it usually does . Don't know it might have lost a little bit of energy.🤔

[@nimlhug138]

While I was watching, my wife noticed that you are left-handed just like me. But with a pretty hand-writing tho.

[@akhurash]

I think one more advantage to using lead acid is that they perform better in colder conditions than the other types. By perform I mean they are not as susceptible to temperature changes as the other types.

[@yousurf374]

And NiMH is ot so bad in cold either and can be charged in cold conditions too.

[@miguellopez3392]

Lithium ion batteries perform better in the cold most cars that don't start in the winter are stuck there because their lead acid batteries failing.

[@thiagocamargoalima]

Awesome video, Scott! Congratulations!

[@adoniscmj3212]

This is really a good way to look at battery power. I use 18650 type cells due to there energy. Lead acid batteries can be dangerous as well. When charging they give off hydrogen gas, that can explode if there is a spark, plus they contain lots of lead and sulfuric acid, so not really the safest option. The 18650 can be dangerous, but as long as you are careful with them, they can really be useful. They are getting safer everyday and they are getting more out of them as well. I look forward to seeing just how much better they can get.

[@dachew57]

Nice comparisons. Would it be helpful to add a 5th point about storage life? For example, lipo's shouldn't be stored for long fully charged, but should instead be brought to 80% capacity. And lead acid has very good shelf life.

[@Proofinc]

Hi guys, what module can I use to make a 10000mah Lipo battery pack ???🙏🏽🙏🏽🙏🏽🙏🏽

[@pokulan]

[@Edu_RJR]

this video is great! really puts in perspective many aspects of why you should use different kinds of batteries in different applications.

[@MrMath-xm9fk]

Great job and study, keep the good work... One more point better to be taken into consideration while discussing the cost is the lifetime of each kind (in other words its number of cycles before loosing 20% of its nominal capacity)

[@T70781]

Nice video. It would be great to see a chart of the information in this video as well as peak power, capacity variations vs. pwr output, power and capacity vs. temperature, lifetime cycles, capacity change as a function of time and charge cycles?

[@greatscottlab]

I like your ideas, but this is a weekly show produced by one person. I can not put that much into one video.

[@Auszeit3]

What Tony Shulthise already said is also in my view of interest! Take the time you need for the video. It would be pretty helpfull for my portable solar devices :D And, nice Video! :)

[@T70781]

GreatScott! I didn't mean to imply that you should do it. Sorry if it sounded like a complaint! I was just thinking about all the times I've needed all that info and couldn't find it in one place, even on dedicated battery info sites. This was great information and thanks for all the time you put in to sharing great videos with us. I always look forward to your videos. You really do a great job.

[@voltlog]

This was a great introductory video, clear and concise. Having all that extra info and comparing all those extra characteristics would make the video too long. Sure, they are useful but after this introductory video the user can go and research those extra parameters on it's own after it has narrowed down it's battery selection.

[@FlorianEagox]

Thanks! This is exactly what I was wanting and super helpful.

[@caesium2339]

when you were measuring the lithium-ion cells and that 65mm dimensions with a calliper that gave me goosebumps as I thought you were about to short it out.

[@brunokertesz2908]

Very nice video!!I waited for your opinion of battery types becouse your one of my favourite youtubers.In my opinion i choose the Li-Ion types ,one of my friends brought me a lot of them.Keep up the good work!

[@CAv-lp2qk]

Worth mentioning also the big difference between a car battery and the deep cycle battery shown! To complicate even more, you can now get "lithium-ion" aaa, aa, 9v ect. batteries with micro USB ports in them for charging!

[@brzydka_i_bestia]

Good video. I have recently found a smashed ps3 controller outside with a lithium ion battery in it. It was not discharged below 3 volts, after charging and testing i have a good battery for my next project :)

[@TheDziobak94]

I would like to say that u didn't mention about one important thing. The capability of draining the energy from the bateries. The Li-Pol and lead Acid ones have probably the biggest amount of that capability. What is more, next important aspect is the cycle-life spans. Any way great job! Always like to watch yours viedos, and waiting for next episodes on your channel.

[@gidimiz]

I saw that some people also mentioned, LifePo4. They are lower in power density, but: They are safer, easy to use, and they are 3.2V almost constant. This save the DC-DC in circuits and also makes it simple to charge. Check them out!

[@andsgiant]

Thanks for educational video, I just dismantle Li Po/battery... It is smell, itchy and hot when touching the layers!!

[@GadgetReviewVideos]

It interesting that you chose the 2450mA NImH batteries branded as Sanyo. I believe Panasonic now owns that brand and the average capacity for them are 2100mA. The price point is also different, cheaper then what you noted. But in the end I don't think it would affect your over all graphing.

[@NicholasAarons]

Fantastic Video Dude. Very Cool. Keep up the great work. Nick.

[@Reinierderu]

One thing you should always take into account when looking at the different batteries and the prices it the amount of cycles you will get out of them. Yes lead acid is cheaper when you only look at the initial cost but you get a lot of cycles out of them and will result in replacing them on a regular basis. Li-Ion can give you a lot of cycles depending on the quality and they have a higher DoD than most batteries thus giving you more usable energy. Lead acid typical DoD is only 50% and when discharged past this point (that you can do safely) will drastically reduce its life time and could cause permanent damage to the unit.

[@erobos111]

Very interesting, couldn't follow your math, however, you explained all very well. Good job!

[@oshavlfarms7239]

One glaring inaccuracy: Lead-Acid can explode catastrophically when overcharged and send shrapnel flying when they do. Also, when overdrawn they can overheat and spring a leak blowing sulphuric acid steam. They're only safe because the charging technology to safely charge them is commonplace.

[@BlackCatRedScarf]

You could include de A123 LiFePO4 cells on this comparison. You should think about discharging capabilities and recharging speed too. Example: LiPo batteries offers great currents and lower voltage drop, which makes it a nice option for low weight and high power projects. Example 2: LiFePO4 A123 technology make the cells able to be charged much quicker than the others (it's not unusual to recharge at 4C or 15 minutes) and these batteries are much more safer than LiPo batteries (most of LiPo batteries are recharged at 1C without much safety nor lifespan concerns and only few higher quality and more expensive cells can handle been recharged above 1C.)

In vape-stores you can get Li-Ion up to 4000 mAh (High Discharge) batteries. High discharge are safer to use, because they can give off high amps without blowing up. The 18650's used in emergency lighting can't deliver high amps without blowing up.

[@GoDroneX]

[@mitsos_306]

Pb batteries have a very wide range of application, not only cars but also UPS and alarm centres and in previous years emergency lighting. This is because they can handle a lot of abuse regarding discharging - charging and of course they are cheaper regarding the capacity. Personally I always prefer them if weight is not a problem for the application.

[@reubenkriegel7639]

Lead acid and lithium pouch cells give the highest available current draw. The pouches can offer ten times the current draw of lithium cylinder batteries for the same volume, although it will be lower total energy.

18650 batteries are classed as 3.7 volts but actually charge to 4.2 volts. You can get Panasonic 18650b 3400mAh cells for as little as £2.50 each from places like gearbest and banggood when they are on sale. Currently those 18650b are selling at £12.64 for 4 cells. Thats about $15 for 4 batteries on gearbest.

surely when considering a battery for a project it's good to know the maximum current you can discharge from it, for instance you can pull 30A through an average 18650, whereas you're never going to pull more than a couple of amps through the NiMH battery

Excellent basic primer but would have liked to see LifePO4 in there. One thing you forgot to factor in to your cost per mAh was cycle life. So if a LiIon batt lasts three times as long as a lead acid and possibly 50% longer than NiMh then you have to adjust your figures accordingly. I know its outside the scope of this video but even though lead acid looks good on paper, cheaper versions of lead acid are only about 70% efficient, although more expensive versions like AGM last longer and are more efficient, they still don’t rival lithium chemistries.

[@sneaky3685]

Nice i think the LiPo is from a small Hubsan Drone :-)

[@asificam1]

Best part about NiMH is the fact you can use them in almost all devices that take AA or AAA cells safely because their maximum full charge voltage is just a shade lower than a full alkaline AA or AAA cell and so they wont destroy devices that were meant for disposable cells. This saves a ton of money since I have lots of devices that use AA and AAA cells ranging from remote controls to powerful flashlights and even a few camera speedlights which eat through alkaline cells. NiMH with its tolerance of delivering their maximum rated current nets me higher performance and lower cost than disposable cells... and since they're standard AA sized cells they're better than Lithium Ion or LiPo. Reason is most devices that use lithium ion are USB charged and have internal batteries that are not removable... this is the major flaw in Lithium Ion technology, not the battery itself but the fact that most devices use fixed internal batteries and if they are removable... they're proprietary. NiMH being made commercially available before the advent of USB chargers is immune to this and this provides unbeatable battery life. Sure the energy density isn't as high as lithium... but it's also effectively infinite. It is ALWAYS faster to switch out the dead batteries for a fresh set than to recharge... especially with how many devices cannot run properly if at all while charging their batteries. If our devices used some Lithium standard like 18650 cells or anything that works that isn't proprietary, I would switch to Lithium tomorrow... well during the summer at least. My experience is that lithium ion seems to suffer more from cold weather than NiMH which usually doesn't take any permanent damage and also seems to still pump out their rated current in the cold. Then again I am testing new Panasonic brand Eneloop NiMH which are absolutely head and shoulders above the competition (any other cells made in that plant perform identically to the eneloops, its just the eneloop brand is easier to get for me than other brands).
