Our Clarke Battery Load Tester is a "must have" tool for professionals and serious enthusiasts. Sulfating and Plate Disintegration occur naturally as batteries age. Re-charging a bad battery only gives it temporary or "surface power". A freshly charged battery may accept and hold a surface charge yet still not crank an engine over.

You need to know if your battery will hold up under heavy loads such as cold or hot starting conditions. Our tester simulates that load by creating a 100+ amp load/demand on the battery. The meter will clearly indicate a battery's ability to "hold up" under load conditions. It's simple to use and will let you know if you need to buy a new battery or not .. No more guessing .
