Lithium vs. Lead Acid Batteries

Lithium batteries offer more usable energy in a lightweight, no-maintenance package that’s safe, reliable, and worry-free.

Why Make the Switch to Lithium Batteries?

Light on Weight; Heavy on Power

RELiON lithium batteries typically weigh one-third less and provide up to 50% more energy than traditional flooded, AGM, or GEL lead-acid batteries, and they provide more power.

Highly Efficient

RELiON lithium batteries offer super-low resistance (and 99% efficiency), allowing much faster charging, with minimal losses. Lead-acid batteries lose power quickly during discharge.

More Hours of Power

Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge. Lead-acid batteries typically provide less usable energy with higher rates of discharge. They are usually limited to 50% of the rated capacity to prevent diminished life.

Ultra Long Life

Rechargeable RELiON lithium batteries cycle 3,500 times or more, and higher rates of discharge minimally affect cycle life. Lead-acid batteries typically deliver only 300-500 cycles, as higher levels of discharge greatly reduce cycle life.
