Batteries and shore power
Have my Int 2019 27FB plugged into shore power in the drive as we do use it often for an extra bedroom or or just a nice quiet spot. Anyway I was wondering if I should be doing anything for batteries besides the usual checking of fluid level. Had our 23 plugged in same way for a year and didn't notice any real sag in battery life or performance when out on the road, but, given the varying battery horror stories I've read here maybe I was lucky with my 23. Any counsel will be appreciated, thanks for being there/here.
