They also find applications in order stand by situations where an occasional high current load needs to be supplied for a relatively short time.
The units are highly reliable and utilise maintenance-free sealed lead acid batteries, which give high discharge currents, long life, and freedom from the plate corrosion failures associated with some other battery types.
