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

I had the same problem as someone else. I bought them in early October and didn't pay attention to the "at least until 2018" label on the blister. So they have a little less life than mass-produced American beers? Strange. It's either that, or the seller is trying to get rid of a ton of batteries he's put up for sale before anyone notices. It's probably too late for a refund, so I'll probably be stuck with 20 useless dead batteries. I learned two things. : Do not buy from MYBATTERYSUPPLIER and if that sounds like a lot to you then it probably is and should be avoided like the plague.
