Charging Time - Shell SBC100 User Manual

Pulse
The battery undergoes the desulfation process to break down the sulfate
and to restore the battery capacity.
Recondition
This stage reactivates the battery for bulk charging after desulfation.
Bulk Charging
The battery is charged at a constant current of 1A. This stage will charge
the battery to approximately 85% of full charge.
Absorption
The charger switches to constant voltage charging. Charging current is
gradually reduced allowing the battery to absorb more power until it
achieves the 100% charged state.
Analysis
Charging stops when the battery is charged to its full capacity. The
charger will check if the charging process is successful. Voltage test will
be carried out to determine the state of charge of the battery. Based on
the result, the charger will decide whether the battery will go to the next
charging step or if it is a dead battery.
Maintenance
The battery is charged at constant voltage to maintain its full charged
state without overcharging or damaging the battery.

Charging Time

The estimated time to charge a battery is shown below. The charging
time is based on a 50% discharged battery and is for reference purpos-
es only. Actual charging time depends on the battery capacity, the
depth of discharge (DOD), age and condition of battery.
