Can AGM (aka dry cell, maintainance free) batteries be reconditioned? By recondition I mean using the "Recondition" mode on smart battery chargers that have this function. Mostly it's to break down the lead sulphate crystals by applying a higher current when the battery is fully charged, either in constant or pulse mode. Some articles I read on the net warn against trying to recondition AGM batteries, saying that it will lead to battery damage because the electrolyte is held in the glass mat, and overcharging disassociates the water from the acid, which cannot be replaced. Others say it's ok. So does someone know something about this subject who can advise me? Thanks.
