After the abuse of my two Harris batteries from the dealer (dead when it was on the lot, and dead when I picked it up after some warranty work), I thought I was going to need new batteries. They would barely last a day of light use. Checked fluid and it was fine, so I pulled the batteries and put them on my Schumacher charger, one at a time overnight, and then both on my Battery Tender trickle charger for the rest of the week until I reinstalled back into the coach the next weekend. They now are acceptable. I’m putting a shunt and battery monitor on them this month to take the guesswork out, but they are largely doing what I need them to do. I’m trying to get solar going and will plan for new batteries when that happens, but for now it’s good. Maybe the Schumacher conditioned them better than the on-board charger, maybe it was because they were being addressed 1 at a time and load balancing was no longer in the equation? I don’t know, it just worked. It’s a cheap try before going new battery route. If you don’t have a “real” battery charger, I recommend the Schumachers; they’ve always worked well for me.
