prevent spontaneous discharging after full charge,
the charger will switch into its ‘‘trickle charge (main-
tenance charge)’’ mode and keep the battery car-
tridge fresh and fully charged.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop machine operation and charge the
battery cartridge when you notice less machine
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 battery cartridge cool down before
charging it.
