Technical FAQs 4

Should you use a lead acid or lithium ion battery?

If you need a battery backup system, both lead acid and lithium-ion batteries can be effective options. However, it’s usually the right decision to install a lithium-ion battery given the many advantages of the technology - longer lifetime, higher efficiencies, and higher energy density.

What is the difference between lithium-ion and lead-acid batteries?

Lead-acid batteries typically use heavy lead plates and sulfuric acid, while lithium-ion battery systems rely on lightweight lithium compounds and organic electrolytes, offering higher efficiency and energy stored. How does battery capacity compare between lead-acid and lithium-ion?

Are lithium ion batteries more efficient than solar panels?

Like solar panel efficiency, battery efficiency is an important metric to consider when comparing different options. Most lithium-ion batteries are 95 percent efficient or more, meaning that 95 percent or more of the energy stored in a lithium-ion battery is actually able to be used.

Why is a lower rated Lithium battery better than a lead acid battery?

Therefore, in cyclic applications where the discharge rate is often greater than 0.1C, a lower rated lithium battery will often have a higher actual capacity than the comparable lead acid battery.
