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.

cartridge.
Overcharging shortens the battery service

Let a hot battery cartridge cool down
before charging it.
4. Charge the Nickel Metal Hydride battery
