Why flooded SLI batteries in GENSET applications fail sooner and more suddenly than in vehicle applications?

Dec , 06 2021

Continuous float charging flooded SLI batteries accelerates the deterioration of polyethylene plate separators to a life shorter than that which battery designers intended. When subjected to continuous float charging, the dominant and earliest failure mode tends to be premature failure of the polyethylene separator. Separator failure typically results in short circuits that prevent the battery fro...
