AGM Maintenance Questions

And at the end of all your spending money on hi $ batteries and way overthinking the charging aspect of it all, you are going to find, as many have already, that your hi $ Agms will not last any longer than the cheap ole LA 6volts from cosco. And when using a PD converter charger, batteries just don't use any water. Under RV deep cycle use, AGM batteries will dry out in a relatively short life, and no way to replace water. So, at least do your expensive overpriced AGMs a favor and charge them w/ a PD charger,.......the only charger that has real technology built in !!
Yeah, lets talk abouy those that don't have a clue ???
