  • Superior Construction: Aircraft class cell construction; lowest internal resistance that provides high repeated cranking current.
  • Unmatched Life-Cycles: When discharged to the BCI recommended 50%, Lifeline batteries provide nearly 1000 life cycles, which is significantly more than other technologies.
  • Rapid Recharge: Lifeline Batteries facilitate a significant increase in recharge rate, with amazingly high current limitations when you properly regulate the charging voltage.
  • Low Self Discharge: Lifeline Batteries self discharge around 2% per month vs. 10% for other batteries.
  • Maintenance Free: With proper charging, Lifeline Batteries require no maintenance. Lifeline Batteries do NOT accept addition of water nor do they corrode their surroundings.
  • Safety First: During normal charging conditions there is no dangerous gassing.
  • Mil-Spec: Lifeline battery construction has passed extensive military shock and vibration requirements.
  • Eliminate Dangerous Gassing: Lifeline provides safety even during severe overcharging as the batteries produce less than 2% hydrogen gas by volume (4.1% is required for flammability in air).
  • Long Service Life: Lifeline batteries currently installed in Marine and RV applications are providing a life span ranging from 5 to 8 years under routine use. Daily and intensive applications also see 3-8 years of use depending on depth of discharge.
  • Solid Warranty: Lifeline Batteries offers one of the best warranties in the industry with our 5-year pro-rated and a one-year free replacement.
