Replacing the Battery

Replace batteries every 3 to 5 years under normal use.
Record the date of installation directly on the battery.
Exceeding the maximum output ratings or
installing the transformer in an outlet that is
routinely switched off causes heavy discharges.
Routine heavy discharges can lead to premature
battery failure.
D8132 Boost Battery Backup: Adding a D8132 Battery
Charger Module supports additional batteries of up to
27 Ah capacity, if required.
The D8132 Battery Charger Module can be used to
connect two additional batteries for a total of four. The

panel plus any connected D8132 Modules and AUX
power supplies must be on the same AC circuit to
discharge evenly if AC power fails. The number of
D8132 Modules is determined by the number of
available outlets on the same circuit. Refer to the
Standby Battery and Current Rating Chart in the
D9412G/D7412G Approved Applications Compliance Guide
for battery standby time calculations.
In applications where the supervision of two
batteries is required by the AHJ, use a D113
Battery Supervision Module.
