What is the life of UPS batteries?

Small to medium UPS batteries generally have a 4-5 year design life, this can vary dependant on the number and depth of discharges together with the environmental conditions i.e. temperature.

For larger UPS systems batteries with an 8-10 year design life are generally used

We advise that the UPS batteries are checked/tested/discharged periodically to ensure that they still functioning correctly.
