Lifeline GPL-2400T 12V AGM 650 CCA Battery. This is a starting/cranking battery, not a deep-cycle battery, produced in the United States. Due to the Lifeline Battery's quality construction, it has an industry leading 2% per month self discharge rate at 77°F (25°C), compared to 10%+ for conventional batteries. Coast Guard approved, DOT Haz Mat Exempt, and longer lifespans than conventional batteries.

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 Battery 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 BATTERY construction maintains the sealed aspects of gel batteries while reducing their chronic recharge sensitivity. In addition, LIFELINE AGM BATTERY technology increases Amp-Hrs., Cranking Performance, Reserve Capacity, Depth of Cycle and Cycle Life.
