Keeping your battery at peak performance The "ReCharge" Battery Life Extender by Kimball Midwest extends and restores battery life up to twice as long as untreated batteries. It works on all types of vented lead-acid batteries, dissolving sulfation to restore battery performance and prevent new deposits from forming. Batteries charge faster and hold charge longer as the rate of sulfation is regulated. The environmentally-friendly extender is ideal for the batteries on trucks, motorcycles, RVs and other electric vehicles.
