Lead Acid battery repair?

Lead-acid batteries are commonly used in automobiles, generators, backup power systems, and other applications. This is mainly due to their low cost and high energy density. However, over time, lead-acid batteries can lose their ability to hold a charge, which can be frustrating and costly to replace. Fortunately, with the help of a battery repair charger, you can restore the capacity of your lead-acid battery.


The battery repair chargers are widely available in the market and also called as desulfators. It works by breaking down the sulfate crystals that can form on the battery plates over time. The Sulfate buildup is a common cause of decreased battery capacity. It can be particularly problematic in lead-acid batteries if they have left sitting for long periods of time.
