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 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 battery cartridge fully after discharging it
completely and recharging a couple of times.
When you charge a battery cartridge from a just
operated tool or a battery cartridge which has been left
in a location exposed to direct sunlight or heat for a long
time, let it cool off. Then re-insert it and try to charge it
once more.
When you charge a new battery cartridge or a battery
cartridge which has not been used for a long period,
sometimes the charging light will go out soon. If this
occurs, remove the battery cartridge and re-insert it. If
the charging light goes out within one minute even after
repeating this procedure a couple of times, the battery
cartridge is dead. Replace it with a new one.
Trickle charge (Maintenance charge)
Ifyouleavethebatterycartridgeinthechargertoprevent
spontaneous discharging after full charge, the charger will
switch into its “trickle charge (maintenance charge)” mode
and keep the battery cartridge fresh and fully charged.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely dis-
charged.
Always stop tool operation and charge the battery car-
tridge 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.
