Superior Mil-Spec Construction
Lifeline battery construction has passed extensive military shock and vibration requirements.

Unmatched Life-Cycles
When discharged to the BCI recommended 50%, Lifeline batteries provide nearly 1000 life cycles. Most flooded and gelled batteries fall between 300 to 450 life cycles at 50% discharges.

Rapid Recharge
Lifeline Batteries facilitate a significant increase in recharge rate, with amazingly high current limitations when you properly regulate the charging voltage. Customers charge 100ah batteries with 500amp chargers routinely.

Low Self Discharge
Much better charge retention rate when compared to flooded and gelled technologies. 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. 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 6 to 9 years under routine use. Daily and intensive applications also see 3-6 years of use depending on depth of discharge.

Trusted by Manufacturers
Lifeline supplys batteries for more than 150 OEM's both in the US and Internationally.
