Do you know if AGM batteries suffer from desulfation?

I've never read anything that says yes and I honestly don't know.




I did a little reading up on them because I didn't know either. It
appears that the answer is .... yes.

Little more trivial information:

Desulfating batteries is accomplished in a couple of ways. One way is also
called "equalizing" and involves the application of a high charging voltage
(typically 15-15.5v) for a period of time.

The other way is using a high frequency, repetitive pulse to the battery to
blow off the sulfated plates.
AGM batteries require this method ... and not the high charging voltage
method. The charger I have utilizes this type of desulfation for all
battery types.
