10 Stages of Charging
With the microprocessor-controlled charging steps of your Pro-User IBC charger, you are able
to recharge your battery to almost 100 % of its original capacity. To ensure that your battery is
kept in an optimum condition, your Pro-User charger can be attached permanently even for
longer periods. The correct charging step is automatically selected by your Pro-User charger:
Step 1: Check
Checks the battery voltage to make sure battery connections are good and the battery is in a stable
condition before beginning the charging process.
Step 2: Recovery
Initializes a recovery process, if needed, for deeply discharged or sulphated batteries by pulsing small
amounts of current.
Step 3: Soft Start
A low charging rate protects deeply discharged or sulphated batteries.
Step 4-7: Bulk
The "Bulk" charging step uses both a high and medium charging rate until about 80% of the battery
capacity.
Step 8: Absorption
The battery charger will deliver small amounts of current to provide a safe, efficient charge and limit
battery gassing.
Step 9 & 10: Maintenance 1 (Trickle) & Maintenance 2
The battery is fully charged and ready to use (the battery icon stops flashing). In this step, the charger
will only deliver enough current to keep the battery full. The battery voltage is continuously monitored to
check if a maintenance charge should be initiated: If the terminal voltage falls below 12.8V (12V
batteries) or 25.6V(24V), the charger will start a maintenance cycle until voltage reaches 13.6V (12V)
or 27.2V (24V). Switching between "trickle-charging" and "maintenance-charging" is repeated
indefinitely to keep the battery fully charged without the risk of overcharging. The battery charger can
be left connected to the battery for an unlimited amount of time.
