Once the charger is attached to a lithium ion battery and then plugged in, the charging process will begin. The charger will subject the lithium ion battery to three steps of charging.

During the first step, the charger enters into ‘fast charge’ mode. During this step, the charger is in constant current mode with the current rate remaining at its maximum rating.

In step two, the charger switches into constant voltage mode (current is no longer being provided at its maximum rate). The battery is 80-95% charged when the LED - indicator changes to orange. The charger will continue to provide a constant voltage until the timer expires.

In the third step, the charge process has stopped. Charging has ceased as no current flows to the battery.
