A SLC-96 is powered by commercial 117V AC, fed into a battery
charger/rectifier. This battery charger continuously charges internal
batteries used in the event of power failures, and rectifies the 117V
AC to the -48Vdc required for the frame.

If multiple SLC-96s are in the same location, then other types of
power plants may be used (to power many SLC96s). In some applications,
no battery backup is used.

As far as the rating on the batteries, I really don't know. I would
guess on the order of 8 hours emergency backup.
