BACKUP BATTERY
All models of S300 expansion enclosures use the same battery (S300-BAT) and bracket kit
(S300-BRK2).
The location and orientation of the
battery inside the enclosure depends on enclosure type.
The battery and bracket kit are sold
separately and the battery can be replaced without
ordering an additional bracket kit.

battery. It
should be replaced every three years to ensure proper operation. Replace
the battery whether or not it has been placed into use by an AC power failure.
