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 tempera-
ture at 10°C - 40°C (50°F - 104°F). Let a hot bat-
tery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery car-
tridge when you do not use it for more than six
months.
