OUT To Battery. Connect the other end to the battery.
Note: The battery is charging whenever the unit operates on AC or DC power.
The Focus battery will completely recharge from its fully depleted state in
approximately four hours, whether or not the unit is in use on AC or DC power.
While charging a fully discharged battery, the LED will continue to blink until 25%
capacity is reached. The LED will then turn solid.
Each of the four LEDs, 25% -100%, will blink as stated above, then turn solid when
they reach their capacity.
When all LEDs illuminate solid, the battery is fully charged and the LEDs will remain
solid for a period of time, then all four LEDs will turn off
.
Wherever storing Focus battery for an extended period of time, ensure that the battery state of
charge (SOC) is not depleted or stored at 100%. Both these conditions can result in
unrecoverable capacity loss. The recommended SOC is 25% to 50% for long-term storage.
