I've had great service with these; https://www.harborfreight.com/4-amp...ntrolled-battery-chargermaintainer-63350.html

Use on DW'S car, 3500 pu and the tractors. Keeps them topped off.

I've had two of those, both open box... the first lasted about 4 years until it let the smoke out of something... got another one because the size is good and it is super convenient and well I found one for like $20 so was hard to pass on

UPDATE: I recently ordered a Schumacher SC1280 4-in-1 charger that is supposed to be compatible with AGM or FLA batteries. It also has desulfation/maintenance/3A & 15A charging. Should be here soon. Will post results! Incidentally: I have a Schumacher SC-600A charger that I hooked up to an old AGM Excel battery. It reached "fully charged" status in less than 15 minutes, at 2 amps!

Im posing to say that agm feature will pay off in longevity. It shortens the life to charge them improperly although it not apparent. It really matters on a four wheeler or lawnmower battery. I like agms but they do require a little special treatment. Keep us posted on your new fancy charger
