2-1-1. Bulk Stage (Constant Current)
At the beginning of the charging process, the flat battery is
charged at constant current (maximum charge current) until the
battery voltage reaches the set charging voltage (Refer to 3-2
charging mode setting).
2-1-2. Absorption Stage (Constant Voltage)
The absorption charging duration will depend on the battery
status.
Before moving to absorption stage, charger will wait for two
minutes then charging at constant voltage until the battery is fully
charged.
Once the battery is fully charged or the charging current is below
6.25% of the rated charging current for 15 minutes, then the
absorption stage ends.
2-1-3. Float Stage
After absorption stage, the battery charger switches to float
stage, maintains the battery at 100% charge without
overcharging or damaging the battery. This means the charger
can be left connected to the battery continuously.
2-1-4. Recondition stage
Every 14 days, the battery charger switches back to Bulk stage
for 85 minutes in order to revive the battery. This prevents any
fatigue symptoms such as sulphation.
