Sulfation builds up on battery plates naturally when chemicals in the battery acid discharge to the point where they crystallize and coat the lead plates. The more the plates are coated, the less charging they hold. High-frequency pulse technology works to actually reduce the buildup of sulfation on the battery plates. SolarPulse Industrial Solar Charging System is a product that reenergizes the sulfates, removes them from the lead plates back into the acid where they have a purpose in cycling. Sulfation of the lead plates is the largest cause of batterydeterioration.
