[RE-wrenches] Battery cell shorting

[Dana]

Has an energy/load analysis ever been run?

How does this compare to the battery bank size?

 

Thanks,  Dana Orzel

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.
