Hey jcurtis! Thanks for the response! They're probably about two years old (came with the RV from the dealership in early 2020). I'm thinking of upgrading to a higher group battery, and I know the one big outage we had last winter probably started their decline. I'll probably look at ordering some 27s or 31s in the next few months. After about an hour of no shore power the voltage jumped from 11.9 to 12.5, and now that power is back on the charger is charging them at 13.6, which is not the boost mode, meaning the charge wizard thing didn't detect enough depletion to go into boost mode
