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 5,000 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.

Is lithium worth it? In this video, RELiON Ambassador Seth Hughes revamps the battery bank in his Airstream and in the process he'll help you understand the answer to this question.

Cash In On Performance

While lithium batteries may cost more upfront, the long-term savings are tremendous. Lithium batteries deliver greater performance and longer life than lead-acid batteries. This means fewer replacement and labor costs, and less downtime.
