Also, some of the batteries from "earlier" in this box have prematurely failed/leaked while in devices

These batteries seem to have the "explode"/leak out problem a lot less than other brands.

Every single one leaks battery acid, toxic and ruins your devices.

Don't trust the rest of the pack as far as I can throw it, and now have to go buy more because I fully expect the ones that are left to crap out in four days.

Just as good as the ones that advertise on TV all the time but at a much better price.

Excellent A+A+A+A+A
