The sulphate preventing the battery from being fully charged and therefore it is unable to deliver its full capacity. When trying to charge a battery in this state it only gets hot and looses water, the gravity of the electrolyte is not increasing to its normal “full charge” state. The only thing you do is killing the battery completely.

When lead-acid batteries are improperly charged or discharged, useful power delivered to loads diminishes. One cause for this is a phenomenon generally referred to as sulfation. One possible method that has been proposed by many to reverse the effects of sulfation is to recharge the lead-acid battery using a pulse charger. To gain a better understanding of the possible benefits of
Charging a lead acid battery will stop the lead-acid re-action. Charging a lead acid battery will not cause the lead to Re-Bond to the surface of the lead element. Many years ago Sears paid an engineer to build a lead acid battery that would
