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.

Follow up to this: AGM batteries require the high freq pulse method of
desulfation.

No amount of "pulsing" on the planet is going to change crystalline lead
sulfate back into sulfuric acid and lead to restore a properly sulfated
battery...no matter what the sales hype to sell the overpriced nonsense.
The pulsing chargers are only good to knock off some of the impurity
surface sulfation in the way of the acid-that's-left from touching the
lead. Crystalline lead sulfate is a very stable 'ol salt, even in diluted
acid soaked in gauze.

AGM doesn't change chemistry.....well, except in boat shops.

I am not a chemist. I use what proves to work.
