The effort put in just for coin batteries, amazing. Well done!

[@Tools-Tested]

Thanks!!

[@rokkuanii6922]

These kind of test should be updated every 3 years, for brands that out source their production. Amazon, Harbor Freight, etc. They can change supplies fast. Ty for your work

[@Tools-Tested]

Yeah I need to update this video, No problem!

[@jjarvis7345]

Hi ​@Tools-Tested Can I second that? Still is much needed info. And greatly appreciated that you did it so thoroughly!

[@michaelgraham5242]

I bought some Nightkonic batteries a long while ago on amazon since it was like 10 bucks for 50 batteries and I just needed a coin battery for my rifle scope. I figured I would just get the one that has a bunch of batteries because I had to change the batteries every few months anyway when I had Energizer and I was tired of spending all that money on batteries that only lasted a few months. I got the Nightkonic and I can confirm that they last WAY longer than the expensive Energizer batteries and at a fraction of the cost! Then I saw this video and it just reassured my decision. I recently put these batteries in my green dot sight on my pistol as well. They last a very long time in that thing which is what I want for my CCW. Great video! Always great to get information and data like this before buying stuff to make sure it's worth it.

[@Tools-Tested]

Thanks, glad to hear you are seeing similar results.

[@jacksonblack9408]

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.

[@Tools-Tested]

Thank you!

[@jimturpin]

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!

[@Tools-Tested]

Yep I agree that intentional voltage drop can tell you which cell is the strongest. Happy top hear you are seeing similar results in your testing!

[@rolandm9750]

Never knew you did this test! Very interesting results and appreciate the effort even a couple years later. The crazy part is there's nearly no correlation between price and performance at all. The Rayovac, yes, and it's even more expensive than nearly everything else; but, the Energizer and Duracell (common well-regarded/known brands) are pricey and perform more or less...terribly. Anywhere from 1/4 to 1/2 the capacity of the leaders, most of which cost anywhere somewhere from 1/10th to 1/2 the price. The Japan cells being in the bottom third, another surprise. Just crazy how all over the place this one is. The only problem I foresee with random "no name" brands you typically find on Amazon...is the consistency and manufacturing/supplier choices. It would stand to reason that a Duracell or Energizer you buy today, would pretty much be the same thing it was when this test was run--still poor but at least still the same. Toshiba you can probably bank on being the same too, albeit in the best of ways. But "LiCB", "Voniko", and "NIghtkonic" great performance but...I'm not sure how much we can rely on these always being as good. Similarly one of the other rando brands might be much better later on too... But the best part is Toshiba is in the same price range as those guys... I agree it's probably the best overall buy. I know what I'm buying next time I need some! Thanks again for the great testing/videos!

[@skeltonjack]

This is one best testing videos I've ever seen. Simple yet comprehensive. And I'd so go far as so say it's better than most Project Farm videos.

Excellent testing procedure. Thanks for that. I bought some Steelton CR2032 batteries at Ollie's. They lasted about half the time of other batteries that I have used. I use these in my bike altimeter/speedometer. Most of the batteries last 60 to 90 days. The Steelton lasted 40 to 45 days. Cheaper isn't always cheaper.

Excellent! Thanks a lot. I wished you'd gone throug testing a couple of them though. In my experience, especially with the cheap ones, there can be quite a fluctuation in the performance of batteries, even within 1 package. I've found that LiCB has a guaranteed shelf life of 5 years.

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.

[@procrastinator1842]

Wow that is a lot of work! Well done. I know what to buy for all my zigbee sensors around the house. I guess the only other thing that could change the test results is the battery voltage under load when in cold temps. I find my car key doesnt like to unlock my car in the middle of winter, unless i put the key in my pocket for a few minutes.

[@dancruze]

I'll take your word for it. Bought some Toshiba ones. Using in an optic.

[@Tools-Tested]

Hopefully it works well!

[@averyjr]

This is an interesting comparison, however I would caution how much weight is put into these results: Maximum listed amp draw for a CR2032 battery is 3mA, with 0.2mA 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 2.3V or so would be enough. However, this would take several days for a single test, so you'd need a more efficient way to run your test

[@Tools-Tested]

Correct it would take a long time at such a low mA, almost would need to have 10 testers running at the same time.

[@kevinwalters5160]

@@Tools-Tested It's interesting to see your results and I'm impressed by how many types you've tested but I am also wondering if you are measuring a different characteristic of the batteries with these high current tests. I've been doing a bit of casual CR2032 testing starting at 10mA constant current and I've settled on 5mA otherwise they seem to discharge then recover considerably. I'm getting far more consistent results of 21-24 hours runtime at 5mA so far... BTW, Energizer quote their capacity on a constant resistance load of 15k!

[@taohan4008]

This is a very important point. I bought a few LiCB battery according to this test unfortunately, they last only 1 week on my car fob! While a good brand one can last 1 year!

[@lucyberlin7108]

Please contextualize this data by explaining how to apply it to choose batteries used in different applications with different stressors -- say, intermittent vs continual loads, and different environments. For example: - garage remote opener (intermittent, high/low temperatures, variable distance) vs. - continuous HR monitor (such as a Polar H10 heart/HRV monitor) used 24/7 to monitor response to daily activity, vs. - a smart bathroom scale linked to a phone (intermittent, indoor, short-range, ?humidity).

2:03 what's the unit of these numbers? hh:mm or mm:ss? Why the number is larger for 25mA than 10mA?

[@devincurrie4145]

Thanks for sharing your test results. At 2:10, I didn't quite understand the difference between the two set of tests 0.010A 2.7V vs. 0.025A 2.0V? Does lower amperage means lower power draw? Why is the voltage for the first set of tests (2.7V) higher than the second set of tests (2.0V but with higher amps)? Does higher voltage means better ability to jump start?

[@RSP13]

I bet the only reason is because he wanted each test to be very quick. Unfortunately that also made all the tests pretty useless unless he proves a strong correlation between his fast test (high current, and high cutoff voltage) and the real test (much lower currents and lower cutoffs). I bet you will find a reasonable correrelation only on batteries with exceptionally low internal resistance. Unfortunately a real test with a more reasonable load (1mA) is done over the span of many days.

[@dancruze]

Unsure how legit the test it but i appreciate the efforts here b/c i cant find much info on which is really the best

[@Tools-Tested]

Yeah its tricky bc most devices draw a very small amperage for a second, but this give an idea how strong the cells are.

Perfect information! The Rigol DL3021 looks mighty cool. I might just have to buy one of those too!

[@mediocreman2]

Just curious, did the batteries you tested have a manufacturing date? Wondering if some were fresher than others. And 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.

[@Tools-Tested]

Two valid points, only about 20% of them had manufacture dates of them 2 months was the oldest. Normal draw would probably be about .0002A for like a car key. Yeah that's the issue It would take a long time to draw them down at .0002, this load tester only goes down to .001. Almost would need one that could do 30 at a time and cycle them.

[@kevinwalters5160]

Energizer's capacity is quoted as 15k constant resistance load which equate to approximately 170uA.

Thanks! yeah I would agree, hard to say.

[@brianaple]

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.

A bigger concern with seldom used devices or adjunct or emergency devices would be leakage. I heard That Energizer spent a lot of research and design, materials, and manufacturing Practice. Later I found a document that I didn't fully understand, but it bears a witness to their efforts. These small cells dissipate energy even in storage, Energizer later claiming 8 years shelf life, down from ten. I have Sunbeams that claim 3 years life. So one has to consider their concerned parameters, for "best" to have real meaning. So are you going to perform eight and ten year tests for leakage? 🤣🤣🤣🤣🤣 I won't be holding my breath as I would be beyond blue. 😉Good work. Thank you.🤠🙏🙏

[@superduper476]

Thanks for doing this. What draw would a tryical key fob for a car use, 2.0 or 2.7? Thanks 😊.

No problem, key fob would draw very little probably a fraction of an Amp. But this test shows which cell is the strongest, which will theoretically last the longest*.

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.

[@Tools-Tested]

Thats interesting, I could see how thats an issue.

Are you sure the Amazon battery was a CR2032? The 2032 battery is 3.2mm thick but they make a CR2025 coin battery too that is the same diameter but is 2.5mm (from the last two numbers of 2025).

I haven't noticed any leaking but I'm sure over time they could.

Kinda surprised you didn't test Jauch. They seem to be pretty prevalent

Looks like they are a European cell, it's hard to find in the US.

Should test IKEA “PLATTBOJ” in round 2 if there ever is one.

Their shelf life is disappointing. Just threw 9 out after 2 years in shelf.
