Charging
Process
The Battery Charger uses a three-stage charging process to maintain the
battery (or batteries) in operational condition. This process is illustrated in
Figure A-1, “Three-Stage Charging Process” on page A–4.
Bulk Stage The bulk stage will start upon connection of AC and with the unit turned
on. The constant current mode is limited to 40 A or 10 A depending on
setting. The voltage setpoint for this stage is 14.2 Vdc. The Charger will
transition to the Absorption Stage upon reaching the bulk voltage
setpoint.
Absorption
Stage
In the Absorption Stage, the constant voltage mode is limited to 14.2 Vdc.
The current will drop as batteries voltage rises. Upon dropping to 4 A, the
unit will transition to the Float charge. This stage will not exceed 4 hours
maximum.
