With my generator running, I measured 19.6V being fed to the old, dead battery. Seems excessive, and probably not the best thing for a new AGM battery.

I've got a couple of small charger/maintainers that have separate settings for AGM and "normal" Lead-Acid. So there must be some difference.

I have a 4000W Coleman generator, a MTD lawn tractor, and a John Deere Gator that are all in their 20's in age. When new battery time comes, is there a downside (or an upside) to getting AGM batteries? I've read that standard lead-acid chargers will damage AGM batteries; true? Any tips...
