voltage.
4. Disconnect the charger's power cord from the receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE:
After operation, pull out batteries from the charger first, and then keep the
batteries properly.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have
not been used for an extended period is not activated, the electric discharge
might be low when using them the first and second time. This is a temporary
phenomenon, and normal time required for recharging will be restored by
recharging the batteries 2-3 times.
How to make the batteries perform longer
(1) Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the
tool and recharge its battery. If you continue to use the tool and exhaust the
electric current, the battery may be damaged and its life will become
shorter.
Malfunction in the
battery or the charger
Battery overheated.
Unable to charge
(Charging will commence when
battery cools).
