Charging method C
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 (or RED 9640). This step allows rapid
charging of your battery until the battery reaches typically 80 - 95% of its capacity.
STEP 2 – CONSTANT VOLTAGE (TIMER) CHARGE
The charger is in constant voltage mode, charging with a decreasing current. The LED-indi-
cation on the charger is YELLOW. The charger is now in timer mode indicated by the YELLOW
LED and will remain in this mode until time interval is completed. 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 to its
full capacity.
The charge voltage is at standby level which means that the charger can continue to be
connected to the battery. 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 constant current
level in Step 1 will initiate a new charge cycle.
