Marine AGM Batteries

Outback Marine has over 10 years of experience with genuine Lifeline marine batteries. We want to make sure that you have the right battery solution including the correct battery charger.

Lifeline deep cycle AGM batteries are manufactured by Concorde Battery Corporation to the highest standards in the industry. They are assembled utilizing the same methods and procedures as Concorde's world famous aerospace grade batteries. This technology combines basic absorbent glass mat (AGM) principles with other patented procedures and special materials. "LIFELINE" batteries are hand assembled using special interlocking cases which are sealed with epoxy resin. Once fully charged and drained, the cells are charged to a slight positive pressure. They have superior strength, do not leak while inverted, and internally process charging gasses. Technology learned from investing millions of dollars in research and years of practical exposure further combine to make "LIFELINE" batteries the best available.

  • User Safe - sealed construction; non-spillable; install in any position if properly supported; submersible without damage
  • Maintenance free (no adding water or repairing corroded terminals)
  • Fastest recharge. (no current limitations with voltage regulated recharging)
  • Deep Cycle (thick positive plates to provide real deep cycle performance)
  • Outstanding cranking performance (aircraft cell construction lowers internal resistance)
  • Best charge retention (especially against flooded cell types)
  • Lowest discharge rates (Less that 3 percent per month unattended)
  • Easily shipped (even via UPS except GPL-8D and GPLAD because of weight)
  • Shock and vibration resistant. (100% of plates are covered with separator liners)
  • Properly supported, LIFELINE AGM batteries with absorbed electrolyte can be installed and operated on their side.
Lifeline cranking batteries share all of the same attributes as their deep cycle counterparts but are optimised for engine starting applications.
