For the past 15 years, Lifeline Battery has been a leader in research, development and production of sealed lead acid batteries for the US Navy and US Air Force. Their current LIFELINE series is designed for marine, RV (Recreational Vehicles), UPS, inverter stand-by and photovoltaic applications in order to correct many of the shortcomings of the sealed gel (GEL-CELL) batteries. LIFELINE AGM construction maintains the sealed aspects of gel batteries while reducing their chronic recharge sensitivity. In addition, LIFELINE AGM technology increases Amp-Hrs., Cranking Performance, Reserve Capacity, Depth of Cycle and Cycle Life over gel technology.

This increased Lifeline battery performance has made them original equipment on many high quality commercial ships and pleasure craft including Island Packet, Pacific Seacraft, Samuel Morris, Elco Electric Boats, Washington Water Bus, Alden Yachts, Hinkley Yachts, Santa Cruz Yachts, Whitecat Marine, Equitable Ship Builders, and Broward Marine. In addition, Lifeline batteries are original equipment on Fleetwood, Vantare, Marathon, Paramount, Vision and Royal motorcoaches and recreational vehicles where inverters such as Heart, Trace and Vanner apply heavy loads to batteries. Lifeline batteries' efficient charge acceptance and low internal discharge make them ideal for photovoltaic (Solar Panel) and UPS applications where sealed batteries are desired.
