Review: Testing results and making sure they work - I have tested these batteries in depth over the last two years and here is what I've come up with versus Energizer version of these same batteries. What I tested them in: Garage door openers, car key fobs and remotes, garage door sensors for alarms, a small flashlight, a headlamp, a handheld radio, couple of other small household remotes etc. A few caveats: All batteries were as fresh as I could get them. Straight out of the packages. The Energizer were the best lithium ones that energizer sells. These batteries were all put straight into use except for the ones I used for shelf testing. 1. In terms of voltage, they are nominal 3V usually starting around 3.3 or so. Some however started lower, even out of the same package, some were ~3.3 other were as low as 3.0 which is starting to show age. Every single Energizer I tried was near ~3.3 Volts. Very little variability with the energizers. 2. When being used in lightly used applications, say a garage door remote, these batteries do fine although the do not last as long as the energizers meaning the mah is a bit less. 3. When shelf testing (Just leaving them on the shelf unused) these batteries deteriorated much quicker than the energizers. After 2 years the energizers showed no detectable degradation and a majority of these batteries showed some sort of degradation just sitting on the shelf while a whole 10% were fully dead with another whole 10% basically still at full charge. 4. In heavy drain applications, say a really bright led headlamp, these things die quick in comparison to the energizers. My overall testing showed: 90+ mah (usually around 92 for the Energizers) and around 64 mah for these batteries. Bottom line: Are they worth it? In my opinion yes, here is why: They cost 1/3rd as much but you are getting over half the capacity. Yes you have to change these batteries not quite about twice as often as the energizers but if it's easy, the price per mah can't be beat. If you need these for a long term stand-by or want to install them in something you want to change as little as possible, use the Energizers or Duracell or the like. Far more expensive, but last longer. For a critical device of some kind, I'd use Energizers or Duracell. For an every day device, I'll use these all day, twice on Sunday. Although I did get a couple that were marginal right out of the package, taking those into account, but accounting for price, how long some of them actually did last, I found this: If you test them first, and put in the ones that have close to 3.3V you'll find they last about 75% of the time the Energizers do. These batteries can be hit or miss, but what do you expect for the price? These are a good buy if you know what you're getting into.

Works great

### ⭐⭐⭐⭐⭐ An excellent value.
*by J***Q on December 30, 2025*

The batteries came on time even during the Christmas madness and seem to work perfectly. I can't judge the battery capacity yet, because we've only had them a short time. However, they have worked for hours at a time for our Christmas decorations.
