I have a couple of batteries that appear to have a single cell shorted. For example: I charge one of these batteries and the voltage after charge is 13.5V.
The battery slowly discharges towards 12.7V over time. If I attempt to use the battery with a moderate current draw, the battery drop instantly to 10.5V - 110.V. It's a standard Sealed Lead Acid battery with a AH rating of 35AH.
I am aware that if I continue to charge the battery to 14.4V, then float at 13.5V, the 5 good cells will essentially be overcharged.
I have devices that work perfectly fine with 10V - 11.0V and thought I could alter a charging scheme for these batteries and such as much life out of them as possible.
Is it feasible to bulk charge them to 12V (2.4V/cell) and float them at 11.25V, and lastly operate them down to about 10.0V? Do you think that I would improve their longevity by applying this new scheme?
