Hi.
Can a cell be qualified by its voltage ?
The battery for a device uses 4 AA cells in series. I installed 4 different brands to make it work (because that is what I happened to have left in my new cells bin). Rayovac, Energizer, Duracell, Eveready.
After months of normal use, the device started to fail with the typical behavior of spent batteries. Measuring each, 3 of them showed near 1.4V; one was 0.7V
Replaced only that 0.7V worst one and the device worked for a few more months until behaved the same. Only one of the cells was really low in voltage again.
Did the battery pack tell which cell of the four was the worst performing and least durable brand ? And then the next worse ?
Replacing only the worst cell every time, can a grading of quality be discerned (for that particular consumption rate/usage) or something else has to be considered ?
