When batteries age or they do spend too much time in a discharged or abused state, sulphite crystals can form on the battery plates which impede the flow of electricity and is the main cause of poor battery performance. To mitigate such a situation we use a Battery Desulphator.

The picture bellow shows the battery cells of a battery bank compared for lack of desulfation (second stripe) and in contrast how they look by constant using a desulphator (first strip of this picture).

Basic Operation:-

Sulphite crystals form when the battery charge is reduced or the discharge cycles are not well suited for the battery. These sulphite crystals act as insulators to the flow of electricity in the battery, seriously degrading the capability of the battery to have electricity flow in it, reducing its charging and discharge capability. Most battery desulphator are using a sharp pulse of current forced into the battery suddenly to "jar" the sulphite crystals and cause internal resonances, both mechanical and electrical, to grind down the sulphite crystals that form so they can be re-combined into the battery acid. For increased performance, they precisely controls the magnitude of the sharp pulse of current, which is adjustable by the user. This adjustment is important as no 2 batteries are the same and no 2 battery setups are the same. As well, battery desulphator, as they work with current spikes, may interfere with equipment connected to the unit. This adjustment allow the user to tailor both, the current spike and at what voltage it is present.
