LIFELINE DEEP CYCLE PREMIUM SEALED MARINE/RV BATTERIES

Featuring AGM ABSORBED GLASS MAT TECHNOLOGY

"Lifeline Distributors Incorporated" internationally markets the highest quality marine batteries available, trademarked "LIFELINE". The 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, but design and optimized for Marine applications. 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, all ideal marine battery characteristics. Technology learned from investing millions of dollars in research and years of practical exposure further combine to make "LIFELINE" marine batteries the best batteries for marine applications available in the World.

In contrast, most manufacturers of "maintenance free" batteries are mechanically assembled with automated equipment and sealed at atmospheric pressure. They leak acid when inverted, dry out from gassing, and are susceptible to vibration and impact damage. In comparison to Gel-Cell batteries, "LIFELINE" batteries offer all of their advantages, nearly twice the expected life cycles, and are not affected by fast charging, the leading cause of Gel Cell failure.

When selecting "LIFELINE" marine batteries, dealers are ensured of providing their valued customers with the best battery available; one with thick positive plates, dense active material, superb grid design, premium insulation, separator liners, sealed construction, and an excellent no hassle warranty package.


LIFELINE MARINE/RV BATTERY BENEFITS

  • 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 MARINE/RV BATTERIES FEATURES:

Why do so many marine and RV enthusiasts choose Lifeline Batteries exclusively for their expensive equipment?

It probably has to do with one of these reasons:

  • Aircraft class cell construction:
    • Lowers internal resistance for high repeated engine start current.
    • Withstands shock and vibration much better than flooded or gelled electrolyte designs.
  • Twice as many discharge/charge cycles as the leading gel marine battery (see chart that follows).
  • Faster recharge; no current limitations with voltage regulated recharging.
  • Much better charge retention than flooded cell types, even at high ambient temperatures.
  • Full recharge after 30 days storage in a full discharge condition 77°F (25°C).
  • Sealed construction with absorbed electrolyte - no shipment restrictions; submersible without damage;
  • nstall in any position; no need for watering; no corrosion on terminals.
  • Cell safety vent valves - pressure regulated, non-removable.
  • Rugged, non-marring polypropylene (copolymer) case/cover.
  • Safety - even during severe overcharge the LIFELINE AGM MARINE battery produces less than 2% hydrogen gas (4.1% is required for flammability in air).
  • Military approved; Manufactured to DOD military specifications;
  • Lifeline Marine batteries are not restricted from shipment by air. Passes DOT 49 CFR Sec.173.159.
