Thanks! You provide a great service! Most of the top brands are still on Amazon I went with the Voniko Comment from : Joseph King

They only discharge 1-2 per year Comment from : Digital Nomad On FIRE

awesome Comment from : supriadi Ramlan

Wow! Thank you for this!!! Comment from : Joey Rakas

I discoverd that coin batteries are not all the same thickness I bought Amazon batteries for my honda keyless entry and it worked intermittantly I messed with it for over an hour I went out and bought Duracells I happened to put them on a table and discovered the Duracell was thicker and it made a good connection while I am very upset with Amazon cheating on the thickness of the battery Comment from : David Desmond

Awesome Video!!! Super helpful!!! Comment from : Hari Tamil Selven

Thanks for the video, I appreciate the amount of work put into this Comment from : FlatPlaneCrank

Er Wat? brAre you telling us at 2:01 that under 001A load Rayovac lasted for 12:11, but under 0025A load (which is 25x more) it suddenly managed to last for 50:01 (more than 4x longer)? A lot longer under an immensely higher load? Really? LOL!brYou need to have some basic scientific literacy to perform such tests At least to be able to spot such immediately obvious BS in your own results and save yourself the subsequent embarrassment I'd understand if you missed this error for some non-contender noname battery somewhere at the end of the list But you actually placed Rayovac first in one of the tests! How could you miss such obvious nonsense in your results?brAnother matter is the commenters here in oozing with "thanks" for this garbage Mostly victims of American education, apparently Comment from : ThatMontmorency

Thanks! Comment from : Jeff Henrichs

This is a really good video, with very surprising results Well done and thank you! 👍 Comment from : SevenSixTwo2012

legit Comment from : Audio Experience

Hey! Thanks so much! Comment from : Howard Hoover

Would love to see a more extensive video with cr1616, cr2025 with tabbed and untabbed I know some motorcycles and such take tabbed batteries Comment from : Seabass

Great job! I think this video will help me I’d be curious to see what Dollar Tree’s Sunbeam test Comment from : Jon Klein

Great video! And thanks for taking your time to do this Which battery regardless of price is the best to keep 3V the longest? I have had decent success with Varta Ikea performed okay but not great And Kodak is a total disaster some batteries dying very quickly I use it for electronic shifting on my bikes hence the critical of using the best batteriesbrSide question, could it vary between battery and battery (same brand)? Because the ones from Kodak it varies so much Comment from : Sebbelito

大事な車のリモコン等は東芝製、AirTagには3個100円のものを使っています。正解だったようでよかった😄 Comment from : あいかわ

I just ordered 5 Toshiba 2032 batteries to replace my depleted supply of Sony batteries BEFORE I saw your test video it looks like I made a lucky guess based on your data and the cost performance ratio My main uses are car key FOBs and digital calipers Comment from : Rob C

I missed Philips Comment from : Daniel Garcia

Thank you Comment from : Johnny Z

5/4/2023 Thank you You put in a lot of effort to produce this video, much appreciated by me because highly useful Comment from : J Rockafellow

Can you let me know what seller your Toshiba cells were bought from on Amazon? I clicked on the link up in the video description, but I want to make sure I buy from the same seller since yours tested so well, there are multiple sellers on the listing Thank you for doing this testing!! Comment from : C L

Now that AirTags are using these batteries this was a very useful video Well done Comment from : Ucfahmad

I'm looking for a coin battery that fits my car key, and I don't know what to choose will be best Comment from : greyll greyll

This is a good ass video shows the country too Wow 👌 😢 Comment from : Blue Dream Chicago

The hero Gotham deserves, but not the one it needs Comment from : AJ P

Hi, wich batteryes have longest life ? Regards Comment from : Bozkurt

The CR2032 is dead in my PS2 I need to replace it, but it need to take the entire thing apart in order to get to it Which battery is the best choice for a PS2 so I don't have to open it up ever again? Comment from : Levy Wilson

I think toshiba link reference is wrong Comment from : Joel Fabelo

Thank you for the big effort to test these for us This is good data! Comment from : LittleMopeHead

Perfect information! The Rigol DL3021 looks mighty cool I might just have to buy one of those too! Comment from : Brian Fischer

If it’s not Duracell or Energizer, just throw it away Comment from : CP11

Thanks for doing this What draw would a tryical key fob for a car use, 20 or 27? Thanks 😊 Comment from : Super Duper

I would be interested to see if the weight of the battery has any positive correlation with the runtime Comment from : Bob Frasure

i found this very useful for my virtual pet i was just gifted a pair of rayovac earlier thankfully relieved! instant thumbs up and a comment for the algorithm! Comment from : sevda

A lot of work was put into this with a lot of data but the main point is invalid That being the run time The test loads them in a way they were not meant to be used Batteries like this are typically put in applications where they last for years, not minutes Maybe draining them in minutes compared to the months they are designed for correlates, maybe not Maybe other factors come into play in the long term, such as self discharge or internal resistance, that these test don't address If I use these batteries in an application where they are drained in minuets your results are valid If I use these batteries in applications where they last for months or years this data does not apply Comment from : Brian App

Thanks so much! You just earned yourself a sub and an like! Any chance I could talk you into a similar test for high draw 18650's? Comment from : Grumbly Curmudgeon Woodworks

Thumbs up even before watching the video Comment from : cyromartinsbicudo

you are best 👌 Comment from : 特别的人

The Voniko link points to CR2016 batteries I didn't notice until the wrong ones arrived on my doorstep 😞 Comment from : Noah Coccaro

I've done quit a bit of battery testing over the years, and you do make a point that the current draw might be low if considered over the long run, but in my experience, that very quick momentary draw is usually to drive a small transmitter that has a low DC impedance so the current that is drawn is very high for just that second or so A lot of batteries don't handle that current spike very well and the voltage "folds" or drops below the devices nominal operational voltage so you can get hit and miss results, often dependent on ambient temperature, or age, either before use, or during I feel the first test you did better captures in a reasonable test cycle time just how much backbone the battery is going to have when subjected to occasional very short momentary high current demand over a longer timeframe For those who use these kinds of batteries in smart home sensors, this is good stuff to know Thanks for taking the time to test all those batteries, and on a random note, I was using the Toshiba batteries and they do seem to work better than the rest I have tested Cheers! Comment from : Jim Turpin

I wonder which battery Casio uses in their watches Or if they make their own i wonder how it compares here Comment from : l3loodyfingers

A lot of fakes on Amazon so I would take this test with a cup of salt Comment from : A L

Thanks so much I was looking for the best, longest lasting battery for my guitar pickup as changing the battery will usually mean needing to change strings too Comment from : Jay Biscanin

There is no Toshiba brand for rc 2032 in my country market placebrI have been using brand like Renata, Maxell, MuRata (Sony), Panasonic, and Energizer Comment from : Le Le

Why is this channel not as popular as Project Farm? Great info, keep up the good work Comment from : JackyChu

Thanks for this! Comment from : Newt Tella

Can you link were you got your tester and load too? Comment from : Brendan Murphy

This was satisfying Can you please add Renata battery's too As of right now in Australia it's hard to get any of those good choices here for cheap But I think renata is aprx 2 aud per battery Comment from : Brendan Murphy

That's not quite realistic to determine what battery is best brThose kind of batteries are almost always used in a szenario where there is very little power drawn over a long period of time Coin batteries are not made for the conditions you created in this test Of what use is a battery that can be used for 20 minutes at 01 A but hast to be replaced every 6 months in a real life szenario? Comment from : David Ryder

what about harbor freight? Comment from : W

Thanks for doing the work Comment from : Rudy

Very Good! Comment from : K M

This is an interesting comparison, however I would caution how much weight is put into these results: brMaximum listed amp draw for a CR2032 battery is 3mA, with 02mA typical, according to Wikipedia A valid test can really only be performed within these specifications, as batteries can perform very differently when under unusually high load vs standard loads I'd love to see a test performed using mA amounts within a normal range, likely 3mA down to 23V or so would be enoughbrHowever, this would take several days for a single test, so you'd need a more efficient way to run your test Comment from : Avery Rawlek

Great test review! I use these for a chest mounted pulse rate monitor/ gps when mtn biking Sony weren't lasting very long but they were probably purchased 5 yrs ago Buying Toshiba after watching this Thumbs up! Comment from : Blowout

Thanks for testing! I wonder what the results would be in a low drain device like a kitchen scale or a digital room thermometer I find cheap chinese cells lasting 6 months on my thermometer but name brand batteries last over a year! Comment from : Phoenix 88

Thanks Comment from : Aryel Sharon

Well done You took a lot of your own time to do the stuff we think about thank you Comment from : Gavin Froling

Thanks for the video, but just curious; how does the battery shelf TIME affect these test results? IE a good battery that was sitting in the warehouse for 2 year before I buy it vs a not-so-good battery that just rolled off the plant? Comment from : keepleft

What a great video! Thanks! Comment from : Terry

Really helpful video Huge thanks for the effort Comment from : dragonsage

Thanks for doing this Really interesting Who would have thought there was SO much difference between brands? Comment from : sineweaver

This is brilliant! You've done a fantastic job on the data side So interesting to see the difference between the low/high draw suitability Comment from : Jackson Black

I’m getting the same thing Kinda tired of looking for 2022 date first available Comment from : TheLUX Network

Awesome video! 😯 Thank you! 🙏🏿 Noted! 📝 Comment from : TheLUX Network

Thank you! Comment from : Monay

Should test IKEA “PLATTBOJ” in round 2 if there ever is one Comment from : yoog

Which is the better CR2032 battery between the Maxell or the AC Delco battery? Comment from : faustsmith

Fantastic! Subscribed Comment from : rashaunny

I'd only heard of 10 of these brands I'm surprised about the large differences in run-times between the brands I don't get through many CR2032s, but recently I had to replace about 5 in a short period of time Thanks for the great video Comment from : SD5

It's nice but Toshiba only seems available in usa, also duracell sell 2 types of cr2032 normal one (220mAh) and an +50 one (260mAh ish one)brbrI use smarttag and airtag, so I was looking for longest life that will work until the battery drops to 2v (not just suddenly die) Comment from : lee x

Thank you! Appreciate your testing and data! I think I’ll go with the Toshiba based off the test results Comment from : TennisTalk

Great video Surprisingly few people saw it Comment from : Geralt Nt

short and helpfull thanks a lot Comment from : mind pixel

Ótimo vídeo!brParabéns!brIrá ajudar muitas pessoas com seu vídeo Aqui no Brasil a bateria da toshiba é a que tem menor valorbrMuito obrigado Comment from : Nélio

Cool stuff Comment from : Thom Theunissen

Just curious, did the batteries you tested have a manufacturing date? Wondering if some were fresher than others brbrAnd what would be considered a 'normal' draw on these? For example, I'm wondering if some of the batteries would perform a lot better under a slower draw, since so many of these batteries are used in things like computers and watches that take years to go bad Obviously you can't run a 3 year test though Comment from : MediocreMan

Nice set of test results 👍 Varta are usually expensive over in the UK as well, but not usually that much of a disparity you are showing here Looks like it is only a middle of the range performer as well Comment from : Three-phase

The effort put in just for coin batteries, amazing Well done! Comment from : Albe
