NERMAK LiFePO4 batteries are a cleaner, more powerful, and safer power solution compared to traditional lead-acid batteries. These maintenance-free batteries have lithium-ion properties that reduce the weight of lead-acid batteries by more than half, while significantly improving performance and capacity.

Lead-acid batteries contain large amounts of lead, which can pollute the environment if not properly disposed of. In contrast, NERMAK's lithium materials are free of toxic or hazardous substances, making them a recognized green battery worldwide. The great durability of NERMAK LiFePO4 batteries allows for easy and safe use at home, at work, or for outdoor needs.

The key battery specifications are as follows: - Battery type: Lithium Ion - Cycle life: >2000 cycles - Rated Capacity: 7.2 Ah (0.2C, 25°C) - Voltage: 12.8 Volts - Weight: 2 LB - Terminal Type: F2 - Charging Voltage: 14.6±0.2V - Dimensions: (L x W x H) 5.94 x 2.56 x 3.7 inches - Continuous Discharge Current: 8A - Peak Discharge Current: 20A (Duration: less than 5 seconds) - Operating Temperature: Discharging: -4°F to 140°F; Charging: 32°F to 113°F - Continuous Charge Current: 5A

NERMAK recommends using a professional LiFePO4 charger to charge the battery to its full capacity. Existing lead-acid battery chargers (wet, AGM, or gel) can also be used. Lithium-ion batteries can be discharged up to 100% without causing damage, but it is recommended to limit the depth of discharge to 80-90% to avoid disconnection by the battery management system (BMS).
