These batteries can be charged with DC18RC only.
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)
If charging light may flash in red color, battery condition is as below and charging may not start.
– Battery cartridge from just-operated tool or battery cartridge that has been left in a location exposed to direct sun-
light for a long time.
– Battery cartridge that has been left for a long time in a location exposed to cold air.
When the battery cartridge is too hot, charging will begin after the cooling fan installed in the charger cools the bat-
tery cartridge. Charging will begin after the battery cartridge temperature reaches the degree at which charging is
possible.
If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the charger
or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.
Cooling system
This charger is equipped with cooling fan for heated battery in order to enable the battery to prove its own
performance. Sound of cooling air comes out during cooling, which means no trouble on the charger.
Yellow light will flash for warning in the following cases.
– Trouble on cooling fan
Incomplete cool down of battery, such as, being clogged with dust
The battery can be charged in spite of the yellow warning light. But the charging time will be longer than usual in this
case.
Check the sound of cooling fan, vent on the charger, which can be sometime clogged with dust.
The cooling system is in order although no sound of cooling fan comes out, if the yellow warning light will not flash.
Always keep clean the vent on charger and battery for cooling.
The products should be sent to repair or maintenance, if the yellow warning light will frequently flash.
