During normal operating conditions the UPS supplies power to the load as well as the necessary
power required to keep the batteries at the proper float voltage. When AC power fails, the
batteries will discharge in order to provide the necessary backup power to the load. It is the
responsibility of the customer to make sure the batteries are not discharged below manufactures
recommendations. After any battery discharge has occurred, the batteries should be recharged as
soon as possible. Batteries will be damaged if not properly recharged right away. See the UPS
manual for more information on charging the batteries.
