The B.E.S.T. (battery electronic sensor technology) sensor is a state of the art electrolyte level indicator.
This is the most user friendly and safest sensor anywhere. The B.E.S.T sensor is green when the electrolyte level is okay. When the battery needs water, the B.E.S.T. sensor flashes red. It's that simple - green means go, red means stop.
