What is the life expectancy of a UPS battery?

-Lead-acid batteries typically have a life expectancy of 3 to 5 years. 

-Lithium-ion batteries generaly can last 5 to 10 years or more, depending on usage and environmental conditions. 

The life expectancy of UPS batteries can vary based on the type of battery chemistry used. 

Lithium-ion batteries offer a higher energy density, meaning they can provide more power in a smaller and lighter package. However, the maiority of UPS today still use traditional sealed lead-acid batteries.
