Review on GP A76 LR44 AG13 Alkaline Cell 1.5V Alkaline Button Cell Battery x (20) Batteries - Long-lasting Power for Various Devices by Hector Trung

I have bought 20 from MYBATTERYSUPPLIER and so far they have been a reliable seller with a good product. The batteries were supplied in two cards of 10 each. Dates were best through 2017. I checked them straight away with a multimeter and they range from 1.498v to 1.605v. So there are a few (6 out of 20) that don't make it and I will contact the seller who always does appears to be available. They're made in China, but that's not a disqualifying factor. It's hard to tell what's killing the battery in the middle of a pack of cards, but I think it was moisture. We use them for cat laser pointers and when they reach 1.378 volts even the cat gives up.
