Tips For Maintaining Maximum Battery Life - Makita DMR109 Original Instructions Manual

SAVE THESE INSTRUCTIONS.
CAUTION: Only use genuine Makita batteries. Use of
non-genuine Makita batteries, or batteries that have been
altered, may result in the battery bursting causing fires,
personal injury and damage. It will also void the Makita
warranty for the Makita tool and charger.

Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely
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 battery cartridge if you do not use it for a
long period (more than six months).
