🔋 Long-lasting Tianqiu AG5 Alkaline Button Cell Watch Batteries - 10 Pack Review

I bought these for my hearing aid. I deducted a star because I found at least one dead person in the package. So far, however, the others have worked and their durability lives up to expectations. The packaging also makes each battery easily accessible.

Although I haven't been able to check the "durability" yet - the voltage deviation on unloaded cells is less than 12mV in the batch - it speaks of a fairly decent quality. Bought primarily for use in Coast Keychain Flashlight and Thermometer. Remember - these are alkaline cells, not usually the more expensive silver oxide cells (e.g. not designed for watch use - they may work, but for a much shorter time).

Hard to beat for the price. I briefly tested some batteries in my laser cartridge and they work great. Finally, I only want to use the laser for a few minutes to continuously check my scope settings. Then the next time I need to use the laser, I'll put in new batteries for maximum illumination. The perfect deal for what I needed it for. I'm glad it was available for my needs and at a great price.
