The Benefits of a MK Gel Battery: *Completely maintenance free. Sealed construction eliminates periodic watering, corrosive acid fumes and spills. *Electrolyte will not stratify, no equalization charging required. Allows faster recharge. *Increases durability and deep cycle ability for heavy demand applications. *Less than 2% per month stand loss means little deterioration during transport and storage. *Tank formation ensures voltage matching between cells. *Transports easily and safely by air. No special containers needed. *Ensures reliable service, support and quality The Benefits of a MK AGM Battery: *Sealed Absorbed Technology: Completely sealed; valve regulated battery with efficient recombination. *250 quality control checks through ISO 9001. *UL recognized components MH17218. *Rated non-spillable by ICAO/IATA/DOT. *Forged terminals and bushings assure no leakage. *Tank formation ensures voltage matching between cells.
