Tips for maintaining maximum
battery life
1 . Charge the battery cartridge before completely dis-
charged. Always stop tool operation and charge the
battery cartridge when you notice less tool power.
2. Never recharge a fully charged battery car-
tridge. 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
battery cartridge cool down before charging it.
4 . Charge the battery cartridge if you do not use
it for a long period (more than six months).
