Charging
1. Plug the battery charger into the proper AC voltage source. Charging light will flash in green color repeatedly.
2. Insert the battery cartridge into charger until it stops adjusting to the guide of charger. Terminal cover of charger
can be opened with inserting and closed with pulling out the battery cartridge.
3. When the battery cartridge is inserted, the charging light color will change from green to red and charging will
begin. The charging light will keep lighting up lit steadily during charging.
4. With finish of charge, the charging lights will change from two red ones to two green ones.
5. Charging time varies by temperature (10°C (50°F) – 40°C (104°F)) that battery cartridge is charged at and
conditions of the battery cartridge, such as a battery cartridge which is new or has not been used for a long period
of time.
6. After charging a Ni-MH battery, it is recommendable that the battery is left inserted in the charger for cool down
and trickle-charging. After 24 hours from completion of charging, remove the battery cartridge from charger and
unplug the charger.
7. After charging a Li-ion battery, leave it in the charger for about 30 – 60 minutes to cool down. And then remove it
from the charger and unplug the charger. Since Li-ion batteries have little self-discharge, trickle-charging is not
necessary.
NOTE:
• The battery charger is for charging Makita-battery cartridge. Never use it for other purposes or for other
manufacturer’s batteries.
• When you charge a battery cartridge which is new or has not been used for a long period of time, it may not accept a
full charge until after discharging it completely and recharging a couple of times. (Ni-MH battery only)
