(25) CR2025 Lithium Cell 3V Batteries

2029 expiration will not rebound to 3 volts which my key fob requires

I don't know if all the batteries are the same but the two that I have used so far did not last very long. I used them in my Fitbit and one only lasted for two weeks and the other lasted a month and a half. The original battery that came with my Fitbit lasted over 4 months so I had expected the batteries to last that long. However for the price, it is an okay deal and I will just run through these batteries pretty quickly.

This was a great deal and I'd recommend it. The only concern I've had is that I think some of the batteries were discharged. I haven't any proof of this and all the expiration dates were valid. Like I said, no proof but some seemed to not last as long as I would have expected. Overall I the buy.

Meh. Bought a bunch of these to go with my wife and Mother in Law's new fitbits. Good thing I got a bunch cause some of the batteries lasted only for a day or two. Some seem to go longer. Fitbit claims a new battery should work for a few months in the unit.

I purchased several battery sizes from various vendors. Prices were all great. However, the premise when purchasing batteries is that they will be "good". My battery tester proved otherwise with some of them.

I've been using these for all my 3V Lithium Cell needs. The difference in CR2032 and CR2025 is in their mAh capacity, and thickness. The last two digits in their name corresponds to their thickness in mm. So the CR2032 is 3.2mm thick, while the CR2025 is 2.5mm thick. In practice you can easily fit the CR2025 in any CR2032 slot with it working well, but you may need to change the battery more often. You might be able to fit a CR2032 into a CR2025 slot, depending on how much extra room they give you and if you can still shut the compartment. With 25 of these in this pack and the already insane longevity that they usually provide I'm not going to lose any sleep over possibly having to change my cycling computer in 6 months rather than 9.

It's not that you wouldn't use these for your grandfather's pacemaker... because, let's be honest, who's buying pacemaker batteries on Amazon? It's more that you wouldn't use these for your gerbil's flashlight. That's how useless these damned things have been. I've bought off-brand cell batteries on Amazon before, with frankly, very positive results. That is, until now. These batteries are less than worthless. My wife received a Fitbit for Christmas. The original battery lasted with daily use, without issues for approximately 3 months. Enter these pieces of useless metal. As soon as these batteries are installed, my wife gets a low battery alert. We're talking approximately 1-2 days of useful life before they need to be put out to pasture. Raw milk has a more useful lifespan than these batteries. Your morning application of deodorant will last longer than these things. Don't waste your money, however insignificant the amount. Spend a couple dollars more and get something that will actually work. DO.NOT.BUY.

These batteries sure beat buying from a brick and mortar store where they are usually 5 to 10 times the price. The batteries work, although I have not had them long enough to know how long they work, but for the price one cannot complain.
