Bests & Worsts Reviews from Amazon

A few months back I bought a 12 pack of these batteries for my trail cameras (size D). In order to verify the claims that these batteries will out perform the standard "Copper-tops" I setup a test. I setup two identical trail cameras next to each other for several months. These cameras sat out in snow storms, rain storms, rising and falling temps, and even a heat wave. During this time they both took hundreds of great photos of wildlife. So aside from having 2 cameras taking the same exact photos I have an pretty impressvie result. The Procell batteries out last the Coppertops by 4 weeks! The Battery life meter said that there was 16% life left on the Procells when the Coppertops were found dead. I just placed an order for a few more packs of these! Great product!
