Low Maintenance Car Batteries come with improved materials and advanced constructional techniques that have either reduced or eliminated the requirement of topping a battery periodically with distilled water to replace loss due to evaporation. These batteries come without the maintenance that makes them attractive. Low Maintenance Car Batteries come sealer for life from the factory and do not require maintenance of the electrolyte levels. The most significant benefit of the sealed design is that it has no service attention that is required which ensures the battery is kept clean and fully charged.
