Great price (at the time of my order) compared to buying locally, i saved $ and didn't burn any fuel to get to a store. I know these batteries are pretty good but have never done a detailed power test or anything like that, i use these mostly for smoke alarms and get at least a year of standby time with them before i replace.Recommended item... Thanks amazon.
