Battery Self Discharge
Would the rate at which a battery self discharges be a way of determining the health of a battery? I have (2) 7 year old Sam's Club GC batteries that have been sitting without charge(battery disconnec...

Last winter, in cold storage, my 6v's were holding strong for 3-4 weeks at a time, without any noticeable self-discharge. This past summer they were over charged a lot, which resulted in excessive gassing, overheating, and electrolyte levels dropping below the tops of the plates on a few occasions. The result is now they are discharging at about 1-1.5% per week, as far as I can reckon. So abuse does seem to affect self discharge. As far as I can tell, charge-ability and discharge under load have not been affected to any great extent.
But as others have said, there are more reliable ways of determining overall battery health.
OP, Did you happen to put a good top charge and/or EQ on those batts before putting them into hibernation? That can make a big difference.
