OPERATION
CHARGING PROCEDURE
NOTE: The battery is not shipped fully charged. It is recommended to fully charge before rst
use to ensure that maximum run time can be achieved. This lithium-ion battery will not develop a
memory and may be charged at any time.
Low voltage charging:
If the battery has been stored with little to no charge for a long period of time, the charger will go
into recovery mode, which will take 20 hrs to fully charge the battery. This will enhance the life of
the battery. Once it is fully charged, the next charge will return to standard charging.
A fully discharged battery pack will require approximately 30 minutes (2Ah) to fully charge from a
discharged state.
1. Charge one battery：
– Plug the charger (1) into an AC power outlet.
– Insert the battery pack (2) into the charger (1).
2. Charge two batteries:
– Plug the charger (1) into an AC power outlet.
– Insert two battery packs (2) into the charger (1).
Note: When charging two battery packs, the two batteries are charged separately. The charger
will charge one battery rst. After one battery is fully charged, it will charge the other battery.
This is a diagnostic charger. The Charger LED Lights (3) will illuminate in specic order to
communicate the current battery status. They are as follows:
Charging Fully
Charged Over Temperature Charging
Fault
LED STATUS DESCRIPTION
Blinking Green Charging
Solid Green Fully Charged
Solid Red Over Temperature
Blinking Red Charging Fault

False defect note:
When the battery is inserted into the charger and the status LED blinks RED, remove the battery
from the charger for 1 minute, then reinsert. If the status LED blinks GREEN, then the battery
is properly charging. If the status LED is still blinking RED, remove the battery and unplug the
charger for 1 minute. After 1 minute, plug in the charger and reinsert the battery. If the status
LED blinks GREEN, then the battery is properly charging. If the status LED is still blinking RED,
the battery is defective and needs to be replaced.
