Solar and inverter.
Last year when I brought my battery in to winter in the garage, I hooked it to the charger and it would not take a charge. I took it back to camping world who installed it new as we took delivery on t...

I have a "7-statge" electronic charger that I can use after each trip, and we're trying to do a spring, summer, and fall trip each year. It nominally charges at 14.8 volts and I've seen 15.0 when it's cold. Haven't used in real summer heat yet to see how it backs off for elevated temperatures. It supposedly does a de-sulfation cycle at the beginning of every charge, and will do a recondition phase if the built in battery test indicates one. It has a sellectable auto,10,20,40 amp beginning charge rate. I had been using 20, but excide says it can be up to 10 times the 20 hour rate which is 40 given my 160 AH combination.
The battery tender claims to do a brief high voltage equalize charge at the end of every daily cycle around 5-15 minutes. It bulk charges at 3 amps (or whatever the panel allows) and gains voltage to 14.4 before starting to taper the amps during saturation. When fully charged the controller does a brief equalization before switching to float. To the extent I've been able to monitor it that seems to all be true.
