Battery charging

Connect the power cable between the power outlet and the back of the charger.
The charger automatically switches between voltages and accepts 100–240
VAC/50–60 Hz.
Place the batteries to be charged in the slots of the charger. The batteries will be
charged one by one in the order the batteries are inserted into the charger.
The status is indicated by the three sets of LEDs in the following way.
Yellow The battery is waiting to be charged either because another battery is being
charged or because thebattery is too cold to be charged.
Blinking yellow The battery is currently being charged
Green The battery is charged and ready for use. After appr. one hour the green light will light
up while the yellow is still blinking. This indicates that the battery is charged to 90 %
capacity and it is ready to be used. After appr. one more hour the yellow LED will stop
blinking and the battery is now charged to 100 %.
Blinking red The battery is faulty and cannot be charged.

Useful notes on the battery system

• There is no risk of overcharging or damaging already charged batteries. If a
already charged battery is inserted into the charger the charging will start but be
aborted after appr. five minutes when the charger senses that the battery is full.
• If the battery is colder than 15 °C the charging cannot be started until it is
heated. This process will be indicated by a yellow light. If the battery is too warm
the charging will not start.
• Full capacity from new nickel-metal-hydride (NiMH) batteries is obtained after
approx. five discharge cycles.
• Batteries are normally delivered pre-charged.
• The batteries will discharge themselves at the rate of approx. 2 % per day while
being stored. It is therefore advisable to charge batteries each time before use.
• Nickel-metal-hydride batteries do not develop the same memory effect as nickel-
cadmium batteries (NiCd) sometimes do. It is therefore unnecessary to dis-
charge the batteries completely before charging.
