Specific Gravity varied widely after topping up.

Letting Some of the plate tops get exposed was the only abuse these batteries suffered.

They've lived a pretty easy life as I never asked heavy loads from them and rarely cycled them, and few of their cycles were very deep. Perhaps this itself is damaging to a deep cycle battery.



I'm going to run them down a bunch tonight. Right now they are at 12.02 volts under a 5.7 amp loads and 23 amp hours from 'full'.
