Adjustable Battery Desulphator 12 to 48 Volts For 40 to 1000 Amp-Hour Batteries

When batteries age and/or spend too much time in a discharged or abused state, sulphite crystals can form on the battery plates which inpede the flow of electricity and is a major cause of poor battery performance. This unit is a basic battery desulphator with advanced control techiques. This unit emphasizes extremely low cost and premium performance.

Sulphite crystals form when the battery charge is reduced and/or the discharge/ 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.

Like most battery desulphators, this unit uses 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, this unit precisley 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 desulphaters, as they work with current spikes, may interfere with equipment connected to the unit. This adjustment allow the user to taylor the both the current spike and at what voltage it is present.

A desulphator will not help batteries with pitted or warped plates, or that have been overcharged to the point where plate damage has occured. They also will generally not do much for auto starting batteries, since those seldom sit around for days or weeks only partially charged - which is by far the main cause of sulphation.

There is no guarantee that this will help your battery. Our own tests have shown that it seems to help sulfated batteries in otherwise good condition, but it is often hard to tell what a battery's internal problems are.
