Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery 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 tem-
perature at 10°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.
4.
Charge the battery cartridge once in every six
months if you do not use it for a long period of time.
