I see that my original post was not clear. I should have said that after the first
instance of a dead battery, after the battery was tested and pronounced good, I replaced
the VOLTAGE REGULATOR.
I'm not sure about the type of electrolyte, whether it's gel or liquid, but I think it is
liquid. The battery is sealed, though. The capacity is 665 AH with "540 CCA."
I've received several responses to check if the battery is draining when the generator is
not running. I should have mentioned that I did this the first time it died, and there was
no current drain when it wasn't running.

I have a 5 kW generator at my house. It runs automatically once a week for a half hour
to charge the (sealed) battery. The first battery lasted for about 10 years! The present
battery is about 2 years old.
Some months ago, I noticed that it wasn't running. I found the battery dead. I took the
battery back to Batteries Plus where I got it; they charged it overnight and tested it
under load. They said the battery was OK. When I started the generator and checked the
charging voltage, it was 13.8V which I thought was marginal, so I replaced it.
Yesterday the generator would not start. The battery voltage with no load was 11.5V. I
left it on the charger all day. Then this morning I checked the voltage and it was
13.5V. The generator started up and the charging voltage was 14.5V.
Do I have a bad battery?
