Has an energy/load analysis ever been run? How does this compare to the battery bank size?

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.
