STORAGE CAPACITY

135 ampere hours (Ah). Eternal Lithium batteries deliver reliable, consistent power throughout the entire 135 amp hours. Unlike traditional SLA batteries, Eternal Lithium LiFePO4 batteries feature a flat voltage curve, ensuring steady power output as they discharge. This means you’ll experience consistent performance right down to the final drop of energy.

ENGINE STARTING POWER

Lithium battery equivalent to 1,200 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive and other applications. Marine Outboards: Please refer to your manufacturer recommendations.

LIFECYCLES (BATTERY LIFESPAN)

Up to 80% capacity for 6,000 cycles under recommended conditions—compared to just 500 cycles for typical SLA batteries. Eternal Lithium batteries offer exceptional longevity, making the cost per use only a fraction of that of traditional batteries.

OPERATING TEMPERATURE

Built for tough and extreme environments, Eternal Lithium batteries outperform SLA and other lithium options. With optimal operating temperatures ranging from -4°F to +140°F (capable of reliable performance down to -20°F), these batteries are designed to withstand harsh conditions. Note: avoid charging below 32°F for best results.

DISCHARGE

135A max continuous discharge, 1500A max pulse. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 50Ah battery.

CHARGE

Peak charge acceptance 135A max for one minute. Please note: this battery should be charged using a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.

INCLUDES ACTIVE BMS PROTECTION

Equipped with an advanced circuit, this battery ensures cell balancing, low and high voltage cutoff, short circuit protection, and high-temperature protection. These features boost performance and significantly extend the battery's lifespan.
