I'm glad you didn't test the EBL's I tested yesterday. LOL Some of those Li-ion batteries did very well, I like the micro USB charging feature. I was surprised to see the voltage drop as much as it did under load. Thanks for another fantastic testing video, and the NiMH update!

Great test! Do the lithium batteries with a USB port allow to be charged while in use? So when charging the battery poles do not lose the 1.5 voltage (or worse have a 5v voltage)

OK - after watching this once, at 1.5X playback, there will be a test . . . First, though, I'm thirsty, so I'm going to go take a sip from Niagra Falls . . .

I know it is another battery test, but it would be great to see you test the CR123A batteries! Both rechargeable and standard lithium.

Thanks very informative I liked this very much.

Thank you Sir. Keep up the amazing work man. This channel is a blessing.

Funny to come across this as today I just bought a pack of JCB branded 4 x AA 1200ma NiMH batteries for £3.99 They reckon 500 recharges and will hold a charge for 3 years, at the price i paid i wouldn't expect to get this.

0:48 I can imagine exactly what Todd was thinking here: "F this I don't know what this means and I'm not saying this" I speak Mandarin and Cantonese and even I can't figure out what they were trying to say before they put this into Baidu translate or whatever they were using

Question. I bought the Duracell rechargeable but they show Made in China? Were yours Chinese or Japanese?

I just discovered something interesting. Have you tried these batteries in an AM radio yet? I just ordered some AAA and they seem to be intefering with the radio reception to the point I cannot find any stations. Though this might interest you. Cheers

The fan RPM is going to be directly proportional to voltage. The Eneloop is a NiMh battery with a nominal 1.2V output that will decline as the capacity drains, like an alkaline battery does. All the others are lithium batteries with a 1.5V nominal output that declines far less than a NiMh battery does as the capacity drains. I'm surprised that the Eneloop held its own against lithium batteries. But where is it in the comparative charts for direct comparison? On Amazon, they're $2.34 each in a pack of 16 which is almost half the price of the cheapest lithium. The Amazon Basics Hi-Capacity 2400mAhr NiMh battery would probably do even better than the Eneloop and it's even cheaper. I'd conclude that unless you need a flat discharge curve that the lithium AA batteries provide, the Eneloop is a better buy with the Amazon one probably being even better..

1200 cycles my ars. 700 at best lol

11:30 i read that as smartools $4.20

Can you do a comparison of Induction heaters for bolt and nut removal? Thanks, awesome channel and great reviews!

Ah we gotta get the Tenergy brand NiMh in there. Best ones I've used anyways.

do you want the turth China : I LIEED It just a liee

Affiliate link won't open Amazon app?

Man, you did a thorough job in these testings! Well done, and thank you. Very much needed research. Btw, any thoughts on Eneloop Pro (black)?

I’ve literally never seen an AA battery with a USB port on it

Tyvm for the review I been whunting to get some of these

Does anyone else skip to charts?

Ginormous battery factory under construction in north Ga at the moment. Guess we'll see what made in the USA batteries look like soon enough.

These Lithium AA batteries get really hot. I tried using Energizer Lithiums to run a powerful LED flashlight and the thing dang near started burning my hand. I thought for sure it would catch fire lol. Needless to say, back to alkalines I go.

Can you please test solar power cell phone charger and also the hand crank chargers

Looks like eneloop ran for 255 min during fan test but it was not added to the chart on which the best performer was judged at 233. Why?

You should do Radiator stop leak to see which one is better so we don’t have to buy random ones.

Anyone else getting steadily depressed by the litany of 'made in china'?

Your effort in testing is exemplary and very much appreciated

would you also recommend Smartools battery for remote controlled toy car?

Love how thorough

I’m in the market for handheld vacuum cleaner or car vacuum a Suggestion I wanted to throw out there

does someone know what happened to smart tools? I can only find them for sale on ebay or on sites I've never heard of before. Edit: nvm, seems there was issues with the batteries and they're unavailable. Hopefully they're fixing the issues.

I don't understand the concept of having plugs on the battery. Couldn't be a more robust, longer lasting battery if all the space were used? Maybe this is to keep from misuse of charging devices, e.g. trying to "fast-charge" at 15w, using a universal NiMH charger on lithium... I could imagine lawsuits happening born from ignorance or stupidity.

I know I'm late to the party but I really enjoy your content and thoroughness so I'm suggesting the following to try and suggest things that might nudge the bar a little higher: 1. I think it would be very useful to track the battery voltage stability levels, which will drop over time, and are much more important for devices needing torque or high power output - for a lot of those uses the 1.2v stuff is a non-starter and I'd like to know which batteries maintain a stable curve as they drain. 2. In the title you put "Lithium" - and I'm no expert but I don't this is is the right use of double quotes. en.wikipedia.org/wiki/Scare_quotes wmich.edu/writing/punctuation/quotationmarks Keep it up, subscribed and sharing you to friends :)

In future battery videos, for both rechargeable and non-rechargeable, it'd be great to see a few other tests. 1) How well they perform after and/or during being exposed to heat or cold. 2) How well non-rechargeable batteries perform and how many cycles they last using specialty battery chargers designed for non-rechargeables. (Yes, those work and are safe if you follow the guidelines.) 3) How many cycles the standard rechargeable batteries last and how well they perform up till the end. And, finally, 4) How many joules can the batteries survive? For example, if there's a surge while charging or short circuit from device usage.

So wish one is better price/quality lithium or non lithium ?

The HIGH in the NiMH test is for the battery`s internal resistance not the voltage, You could have done the li-ion discharge test on the Maha C-9000 using DISCHARGE only, People test Alkaline on this charge all the time, And it should have been fine with the Li-ion battery`s

Would it be weird if MR.PF wore a lab coat to conduct all his tests? I love the level of ingenuity that goes into all the tests. I used to watch the videos that only pertained to my potential purchases but now I just watch them just to watch.

Video editing project must look like a nightmare. :)

I’ve tested the maxlithium and blackcube and found that they don’t hold charge for long. I have some 10mA LED candles and they only last for 60h or an equivalent of 600mAh, in the course of around 8 days (around 8h a day). High self discharge, making them useless for most applications.

Try eneloop pro. They are even better then the white ones.

Another video I enjoyed so much.

Thank you for your testing! I had to sift through the german Amazon to find any of those, but i settled on the Blackube, as all the others that i could find had stupid long delivery times. What i would appreciate though, would be an overview screen with all the values tested, that would be quite nice to have after watching and hearing your opinion

why did not test amazon basics one?

PROJECT FARM - How about a video comparing 9 volt rechargeable batteries both lithium and Nimh ?

I asked myself if button cells like 2032 have such big differences too if AA batteries and such have a difference like this.

I have been using the ENELOOP PRO 2500 miliamps 1.2 volts bought 4 cause i read they where made by Sanyo b4 Panasonic took over made in JAPAN then bought 8 more the last 4 I forgotten where I put them found them n they still had lots of charge in them after 5 years storage it doesn't even crosses my mind these batteries will ever let me down the first 4 I bought at least 6 years ago n they are still perfect wished u tried them instead of the lower priced ENELOOP would a been interesting

Have you ever tested oil stop leak

anything not made in china?

Add on to this one, how about testing lithium vs SLA UPS 12v (6V deer feeder) batteries?

Funny, even though Eneloops were great years ago i returned to using non-rechargeables. The convenience combined with general quality increase plus price, *you can get a 100 aas for like 15$ now* was just better.

im late to the party todd, due to texas! anyways can you do a quick shoot out between the nickel recharge and the lithium, it looks like the solar light batteries are holding up pretty well after 2 years

Brilliant videos but so much information can be a little overwhelming.

please do a comparison test of acid based auto vs lithium based auto batteries. Thanks Ron Oh and please stop destroying brand new engines/motors!!!!!!! Thats just so hard to watch!!!!!

Have you tested Solar Power Charing banks? I would like to get some this summer but there are many options

Would like to see a review of the USB/iphone/android/etc portable power banks (the ones that are about the size of a thick phone). Especially ones that advertise around 30,000 mAh. Thanks for all the other videos. You have saved me a lot of money and trouble over the years

Test Request: Can you do a test to see which AA battery survives a shotgun blast the best? (Cough.. Demo Ranch.. Cough) - Love your channel too!

Please make a comparison of the locking pliers like Irwin, Milwaukee, Gedore, Knipex, etc.

Please make a comparison of the pliers like Irwin, Milwaukee, Gedore, Knipex, etc.

Surprising results. The cheapo battery did well - proves that price doesn't mean it's cheap or on the other hand good. Keep up these great tests!

@Project Farm, would you say from your testing that if you want constant voltage get lithium? Not sure on the price point of the NiMH compared to lithium?

I predict a vapcell spike in sales

could you test portable power station vs gas generator?

Great video!!! Thanku

Please, please, please compare generators!

What is the scale you are using to weigh the batteries? Perhaps you could do a test of this type of scale (50 x 0.001g) for accuracy, especially in the low mg range.

Do they make AAA 1.5V lithiums, yet? If they do, could you test those? I am not sure if you can extrapolate AA test results to AAA with the same brand. They could have slightly different chemistry. The reason for my interest in AAA's is that I have a 3-AAA headlamp that eats batteries, but is also pretty bright. I have not tried NIMH's because I figured the difference in voltage would run them down sooner. Thanks for the work you do!

Thanks for this interesting test!

6:15 4-solt charger

I’m just sad none of these where made in USA

Better check these out for the next round irmys.info/more/mZWcpmymmZmLpmk/fy-lm-h-y.html

Ye

The "HIGH" On the PowerEx charger at 12:40 means high internal resistance, not high voltage. I have the identical PowerEx charger.

👍👍

Another awesome test. I am curious to know how these Litthium batteries would perform at low temp in a future test. It would be interesting to compare vs NiMh and non-rechargeable batteries. at 0°C and -10°C. at -15°C lithium batteries would stop working I guess. I have in mind headlisght use in winter time for instance. Typically a real outdoors use case when you may need mAh and volts on the field at low temp.

Have you ever tried to power an engine by hydrogen produced with water, electricity and baking soda or increase the gas mileage using the same method?

Thanks for doing this, it informed my decision on buying USB rechargeable batteries for a portable soldering iron.

I've had Kirkland alkaline AA's leak.....no bueno!!

Would love to see you review steamers, not the handheld ones but next size up "mid tier". Love your methods for testing products.

In your opinion out of all the rechargeables you used, what one is the best?

Can you test EBL lithium and add that to your test results? Great videos love your channel

Great video! I love watching your tests :) I've bought several years ago for night hiking a few Kentli 2800mWh AA Lithium ion rechargable batteries. They are also good and worth a mention.

I'd like to see you test Torque Wrenches. I saw and ad for Harbor Freight torque wrenches for $9.99 (1/4, 3/8, or 1/2") How accurate can they be for 10 bucks??

Would these lithium rechargeables beat a Kirkland alkaline in the fan test?

No extra words were used in the delivery of this review. Thanks for the quick and efficient deliver of relevant info.

I Use Energizer Rechargeable's In My Sony Elph 3000 Digital Camera & They Work Like A Charm.

Great video! Just a thought, it might not be the best comparison between NiMH and L-ion if you discharge them at different rates with different instruments. But if you were just re-testing the NiMH batteries after hard use, then no big deal. Thanks for making these!

Off topic.....would you test different 3-6 gallon air compressors?

please! test EBL lithium ion 3300 vs smartools 2600 Thank you!!

Now you HAVE GOT TO test some NiZn Batteries!!!!!!!!!!

Truly the most interesting channel on planet earth 🌎. 🚜

"Next, I'ma try to find stuff that's NOT made in China". Good luck with dat. WTF is going on in the world...

... "is made in China". But, why?!

Thanks heaps. The worst thing is they made everything in Australia AAA now. So I cant use this info anymore. Even the Lego motors are all AAA. Cheers for your long term testing. Love it!

ENELOOP = IKEA LADDA

0:58 -- I'll be damned.. there IS such a thing as a 1.5v rechargeable cell... I always thought it was 1.2v for rechargeables and 1.5v for everything else (even non rechargable lithium)

I approve of this video! Thanks for the information! The fan test reassured my experience with using LiMH Batteries in mini Synthesizers. They run for a long time but then suddenly die without the battery indicator dropping.

Could u please do a test like this with 3s lipo rc car batteries, can be expensive

Thank you so much for testing this. Ive been going through batteries like their nothing. And these will save me a lot of money. I haven't bought any rechargeable batteries because I've had bad experiences in the past.

Here comes a request. So in the fishing kayak and canoe department, there are quite a few anglers out there that are always looking for the best of the bestus LiFePO4 batteries. Some tout Nocqua as victor secondary to it's smaller and lighter weight. Some will rave about FPV LiFePO4 and it's completely sealed housing as best. I bought a Amped Outdoors LiFePO4 because of the conclusive evidence demonstrated by super awesome Ice Hole Power (YT channel) testing. Jeremy, however, didn't test the the FPV. I am just wondering if the name brands are hyped up to be significantly better than the generic no-name brand. Now the real question is longevity. Do the budget brands last as long, and if they don't, does the cost difference of the name brand justify this price increase?
