Yes batteries can fail over night you only need 1 cell to fail in the string to kill the whole lot.

This is also from one of your earlier posts.

"Each Fullriver DC Series, Full Force and Full Throttle batteries are designed to be deeply discharged and recharged hundreds of times. With the sealed, maintenance-free aspect of all our AGM batteries, you can simply "Set it" and Forget it"."

The generator was only being used twice a day to recharge the batteries"

So full river are telling you the truth, you can deeply discharge them "HUNDREDS of times" I think you said you have had them 9 months and had to run the genset twice a day so in effect 2 cycles per day.

9 months x 30 days = 270 then times 2 cycles per day = 540 cycles, so you have had the "Hundreds of cycles" they claim is possible.
