UPS does not provide expected backup time.

The UPS’s battery is weak because

the end of its service life.
Charge the battery. Batteries require recharging
after extended outages. The batteries wear faster
when in service more often and when operated at
higher temperatures. If the battery is near the end
of its service life, consider replacing the battery.
