I like the idea of a gel battery, if anyone knows what size, brand(s), and where to get. The small RV access door is no good for filling the battery and it led me to a problem...
About a year or so back, I had a lot of posts and advice from here about cleaning my battery support and tray after seeing how my overfilling had allowed acid to do some ugly corrosion. Baking soda let to dry and brushed off, sprayed w/ Krylon Hammer paint to fix the corroded stuff. Martha reinforced the flimsy strap that was coming undone.
At nearly 3 years now, I'll bet the battery could be needing to be replaced.
I asked about gel back then, and am not sure anyone knew a lot about them, does anyone have any info about them today? Or maybe what about maintenance free deep cycle?
