Explanation of Li-Ion battery charge cycle
(See tables for methods for each charger model.)
Charging method A
STEP 1 – CONSTANT CURRENT CHARGE
To start a charge cycle; connect the charger to the mains.
The charger is in constant current mode, charging with the maximum current indicated on
the charger, the LED-indication on the charger is ORANGE. This step allows rapid charging
of your battery until the battery reaches typically 80 - 95% of its capacity.
STEP 2 – CONSTANT VOLTAGE CHARGE
The charger is in constant voltage mode, charging with a decreasing current until the current
is below the chargers charge termination level (indicated on the charger). The LED-indication
on the charger is ORANGE. The battery is charged to its full capacity at the end of this step
STEP 3 –CHARGE COMPLETE
The LED-indication on the charger is GREEN and the battery is fully charged.
For Li-Ion batteries the charge current is zero and the battery has been charged it its full
capacity.
After end of charge battery voltage will remain at “Step 2” level even if output voltage of
charger is indicated as lower in the diagram. The charger will return to Step 1 if the battery
is used. A load larger than the cut-off current will initiate a new charge cycle.
