Gel/AGM batteries are designed to go as low as 1.74 volts per cell (around 10.5v) with no issues. I find these batteries in day to day use that routinely last 5 or more years discharged this low on a daily basis. But beware, your generator best be in top shape to start at that voltage...

Batteries must be read for charge at rest under NO load and with the surface charge not being a factor. Most meters are read with a system load as they are integrated into the system not independent. Also an idiot light does not a meter make, at best an indicator.
Just a couple comments.

Bought 4 Sams Club 6 volt batteries back in 2005. Replaced charger with a Progressive Dynamics 60 amp charger with charge wizzard.
Ran them down to 12 volts before charging them back up to a FULL CHARGE. They lasted 10 years.
Its not just batteries, it the charger (not the generator) as well as keeping them watered and clean connections.
This was in New Hampshire not connected to power during winter.
Would charge them up, hit the disconnect switch. Simple and sweet.
Still running the original Interstate batteries in our current rig, again going no lower than 12.0 volts. Still getting me thru the nights but due for another set.
Treat them right and they do the same to you.
Too many experts trying to make it sound like a major production.
Enjoy RV'ing, I sure do!
