Re: AGM Battery Upgrade and Charger

If you cut and paste this into a google search line, you will find a lot of discussion on AGM batts: agm batteries

Some quick notes. You will need to have a way to keep them fully charged or get them there often, or they will not last. Harder to do on a mooring. AGMs can take a much larger charging load than other batteries, which can overload your engine alternator and burn it out. I believe it can overload a charger not made for them as well. You typically need a temperature and/or charging regulator with AGMs.

Pros will have better details, but chargers that are made for AGMs, seem to have an AGM setting.
