What is Battery?
This refers to the secondary battery, usually sealed Lead Acid battery, used to store the charge to be used in the absence of utility power. Most 500 and 600 VA UPSs have a 7.2 AH battery inside. UPSes with external batteries also exist that allow additional batteries to be added to increase backup time. Larger UPSes use Lead Acid batteries as used by heavy vehicles for backup.
