Title: Finally, a way to sort the weak from the strong
Review: I'm constantly amazed at the frailness of rechargeable batteries. The manufacturers claim an almost infinite life for these expensive little pieces of "green" technology but as a newspaper photographer, I keep finding them failing at the most awkward moments. The Mini Multi-Battery Tester finds those batteries that just aren't up to the task before failing at some critical time. Huzzah for the ZTS Mini Multi-Battery Tester!
