[RE-wrenches] Battery cell shorting

[Kirk Herander, VSE]

Hello,

 

I have an off-grid battery / generator / SW4024 system which has destroyed
-3- sets of batteries in the last five years. By destroyed I mean multiple
batteries having shorted cells, with electrolyte literally steaming out of
them and bulging badly. The last two sets were Rolls T12-250's. The first
set was Trojan T105's. This system has no solar, and I would not be
surprised if the generator ran 10-12 hours a day charging the batteries, for
the residents don't believe in energy efficiency. I could see the batteries
cycling to the point of being useless after a couple years, but the scary
thing is the condition I've witnessed multiple times now. Any ideas as to
why this has happened repeatedly across different brands of batteries?
Thanks.
