WHAT IS SULPHATION?
The lead sulphate crystals that form in lead acid batteries are generally dissipated by normal charging. During extended periods of inadequate charging – think winter, with heavy use of ancillaries – these sulphates form crystalline deposits on the negative plates that obscure the battery’s active material, severely impacting on performance. A pulsed charge is believed to avoid, reduce or reverse this condition.
