The battery plays a key role in the overall
reliability and availability of a power
protection system. It supplies the energy
required by the critical load in the event
of a mains utility failure or when the input
mains voltage and frequency are outside
the acceptable values. Moreover, the
battery represents an important share of
the total cost of the UPS, and therefore
battery care and management are of
paramount importance when a UPS is
designed.
