Would AGM really provide more juice?
You should NEVER need your generator to watch TV.
I can turn on 3 TVs and go through the night, of course I never need to, but I could.
Your batteries are only getting worse because you are constantly under 12.2 vdc. I could easily tell you to go buy two new batteries, but that does not mean you don't have some other issue that is drawing or damaging your batteries.
But if you do buy new AGMs, verify your inverter has a intelligent charging program, and NEVER let the AGMs go below 12.4vdc which is 50% SOC. I cut mine off at 12.5vdc which I admit is overkill, but because I don't need all of the available capacity, I can do it.
