Tips for maintaining maximum battery life

1. Charge the battery cartridge before com-

pletely 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.
