Lifeline Batteries produces the highest quality AGM batteries for Marine/Boat and RV/Recreational Vehicle applications. Each sealed lead acid Marine/RV battery is hand crafted in the United States. 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 performance has made us original equipment on many high quality commercial ships and pleasure craft including Lazarra Yachts, Island Packet, Pacific Seacraft, Viking Yachts, Elco Electric Boats, San Juan Yachts, Alden Yachts, Hinckley Yachts, Santa Cruz Yachts, Christensen Shipyards, Blue Water Yachts, and Broward Marine. In addition, we are original equipment on Monaco, Vantare, Marathon, Parliament, Country Coach and Royal motorcoaches and recreational vehicles where inverters such as Heart, Trace, Xantrex, and Magnum apply heavy loads to batteries. Our Batteries efficient charge acceptance and low internal discharge make them ideal for photovoltaic (solar) and UPS applications where sealed batteries are desired. 32 12 57 700 9.78 5.17 6.83 5 Year Pro-rated by Manufacturer SLA Concorde Battery Yes http://site.apexbattery.com/logos/lifeline.jpg New M8 Threaded Insert (Copper Alloy) LL
