BEFORE: The first photo shows a lead-acid battery plate with heavy sulfation buildup (lead sulfate deposits) indicated by the chalky, light gray plate coverage. As part of the test, the company discharged the battery completely. The plates were so sulfated, discharge time lasted only a little over 13 minutes.

AFTER: This is the same plate 18 days after an Industrial 12-Volt Solargizer was installed. Sulfation buildup (the deep gray areas are active plate material) has been removed. This time the battery discharged for over 33 minutes. That means discharge capacity increased over 250%.
