4.4 Battery Maintenance
Lead-acid batteries contain dangerous voltages, currents, and corrosive material.
Battery installation, maintenance, service, and replacement must only be performed
by authorized personnel.
WARNING!
4.4.1 Battery Notes
• Always refer to the battery manufacturer’s recommendation for selecting correct FLOAT,
ACCEPT and REFRESH charge voltages and REST Mode setting. Failure to do so can
damage the batteries.
• Batteries are temperature sensitive. During extremely cold conditions, a battery’s charge
acceptance is reduced and requires a higher charge voltage; during extremely hot conditions,
a battery’s charge acceptance is increased and requires a lower charge voltage. To
compensate for changes in temperature, the battery charger used in the Power Supply is
temperature compensating.
• If the batteries appear to be overcharged or undercharged, first check for defective batteries
and then verify the correct charger voltage settings.
• During preventive maintenance, check battery terminals and connecting wires. Clean battery
terminal connectors and ensure they are correctly torqued (torque specifications are listed on
the top of the battery). Spray the terminals with an approved battery terminal coating such as
NO-OX.
• If installed, disconnect the Smart AlphaGuard prior to measuring battery voltage.
• Refer to the battery manufacturer’s recommendation for correct charger voltages and the
Power Supply operation manual for corresponding charger settings.
• Number the batteries (3,2,1 left to right as shown in the Installation Procedure) inside the
enclosure for easy identification (refer to the appropriate enclosure installation guide).
• Establish and maintain a battery maintenance log.
• If batteries are being stored prior to installation, recharge per manufacturer’s specifications to
ensure optimum performance and maximum battery service life.
• The XM3-HP has a refresh “boost charge” feature specifically designed to deal with a battery
coming out of storage. See Section 1.2.3, Charger Modes of Operation for instructions on
initiating REFRESH Mode.
