BATTERY CHARGING
Note: Freedom battery chargers are ON
whenever AC power is connected to the
charger input. The charger can be turned OFF
using the CHARGE switch on the front of the
unit. This sequence will occur each time
external AC power is available. The charger
can be turned ON/OFF using the Remote
Control Panel or Link Instrumentation.
Each time the battery charger is engaged,
the three-stage charger proceeds automatically,
resulting in an efficient complete charge and
safe battery maintenance. Use of the Remote
Control Panel or Link Instrument provides the
ability to periodically apply an equalizing charge.
Refer to Remote Control Panel or the
Link Instrument Owner’s Manual for more
information.
The battery charger stages are:
Stage 1 - Bulk Charge During the bulk
charge stage most of the energy that has been
consumed during discharge is returned to the
battery bank. This phase is engaged as soon
as the battery charger is activated. Full rated
charger current is delivered to the battery bank
until the bulk charge voltage limit is reached.
This results in a relatively rapid recharge.
Generally, a wet cell battery bank should
not be charged at a rate that exceeds 25% of
its capacity.
