I have a few AGM boat batteries that are sulfated up and in need of a
charge. They are off the boat and in the gararge but my current charger
won't charge them.


WRONG....You have a few AGM boat batteries that are sulfated up and in
need
of REPLACEMENT, not charging. Charging isn't going to fix them....


According to several sites that I just read .... AGM batteries can indeed be
desulfated if they are not too far gone. Worth a try anyway.
