gel vs lithium batteries

Key differences between a lithium-ion- and gel/lead acid batteries.

1. Battery life cycle

The lifespan of batteries is more accurately determined in cycles than in number of years. The more cycles a battery goes through, the greater its wear and tear and shorter its lifespan.

One charge cycle = When you charge your batteries after you used it to power your appliances.

How much capacity you used before the battery was recharged, also influences it life cycle. Lithium-ion batteries have more cycle life than gel batteries and they generally last longer.

2. Battery Density & Efficiency

Lithium batteries have a bigger energy storage capacity available in a smaller physical battery. Its improved energy density capacities require less space and can thus be installed in smaller spaces. The improved solar-power-to-watt conversion efficiency of lithium batteries enables a user to have more watts available than what an lead acid battery could produce with the same amount of solar energy. Depending on the configuration of your system, it could also mean you buying fewer solar panels and less battery capacity. Gel batteries takes longer to recharge to full capacity than lithium batteries.

Luceat Solar prefers to install Lithium ion batteries that has a longer expected lifetime (10+ years) and that offers the highest standards of safety, reliability and longevity.
