Lithium vs. Lead-Acid Batteries

Compared to lead-acid and other lithium batteries, lithium iron phosphate batteries offer significant advantages, including improved discharge and charge efficiency. In addition, the longer life span and ability to deep cycle while maintaining power makes them a worthwhile investment and a smart long-term solution.

Lighter Weight:

Lithium batteries are typically half the weight of lead-acid batteries.

Drop-in Ready:

RELiON lithium batteries are available in a variety of BCI standard sizes for easy drop-in replacement.

Longer Life:

Up to 10X longer life span compared to lead-acid batteries.


RELiON lithium batteries are maintenance-free – no watering, no corrosion. Low self-discharge means the batteries don’t lose capacity when they’re idle, assuring that you have the energy you need, every time you need it.

More Useable Capacity:

25-50% more usable capacity than lead-acid batteries with full power available through most of the discharge.

Extra Safe:

Inherently safe chemistry coupled with the BMS and protective features at the individual cell level provide maximum protection.

Low Temperature Series

Our Low Temperature Series batteries look and operate exactly like our other batteries, with the same power and performance. They have the same charge time at above-freezing temperatures and feature the same dimensions, configuration, and connectivity of its standard counterparts. They’re an ideal upgrade for those who are still using lead-acid batteries in low-temperature environments.
