Conditioned refreshing charge
• When the battery cartridge is employed in the following conditions, press the conditioned refreshing button. Then,
the battery cartridge will be activated by conditioned refreshing charge.
• The battery cartridge is new and out of use.
• The battery cartridge has been UNUSED for approximately six months.
• Over approximately one week has passed after the battery cartridge was last inserted into this adapter.
• You intend to check the battery capacity.
• After conditioned refreshing charge, the refreshing lights indicate the battery capacity for a new battery cartridge.
Cooling system
• The charger is equipped with cooling fan for heated battery in order to enable the battery to prove its own perfor-
mance. 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, adapter and battery, which can be sometimes 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, adapter and battery for cooling.
• The products should be sent to repair or maintenance, if the yellow warning light will frequently flash.
Conditioning charge
Conditioning charge can extend the life of battery by automatically searching the optimum charging condition for the
batteries in every situation.
The battery employed in the following conditions repeatedly requires “conditioning charge” to prevent fast wear out. In
that case, yellow light lights up.
1. Recharge of battery with its high temperature
2. Recharge of battery with its low temperature
3. Recharge of full charged battery
4. Over-discharge of battery (continue to discharge battery in spite of down of power.)
5. Recharge under broken cooling system
The charging time of such battery is longer than usual.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely discharged.
Always stop tool operation and charge the battery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.
3. Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.
NOTE:
• The battery charger and adapter are for charging Makita-battery cartridge. Never use it for other purposes or for
other manufacturer’s batteries.
• When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it
may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the bat-
tery cartridge fully after discharging it completely and recharging a couple of times or after refresh charging.
• If you charge a battery cartridge from a just-operated tool or battery cartridge which has been left in a location
exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while.
Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger. When the temper-
ature on battery is more than approx. 70°C (158°F), two charging lights may flash in red color, and when approx.
50°C – 70°C (122°F – 158°F) , one charging light in red color.
• If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the charger,
adapter or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.
• Any of the following conditions indicates damage to the charger, adapter and/or battery cartridge. Ask your Makita
Authorized or Factory Service Center to check them.
1. The charging light does not flash (green) when the battery charger is plugged into a power source.
2. The charging light does not light up or flash (red) when the battery is inserted in the adapter port.
3. Normal charging is not completed at even more than two hours after red light comes ON at start of normal
charging.
4. Refresh charging is not completed at even more than 15 hours after start of refresh charging.
