(2) Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are
as shown in the Table 3, and batteries that have
become hot should be cooled for a while before being
recharged.

batteries
Temperatures at which the battery
can be recharged

32°F–122°F
(0°C–50°C)

Approx. 32 min
NOTE
The recharging time may vary according to the
ambient temperature.
4. Disconnect battery charger from the receptacle.
CAUTION
Do not pull the plug out of the receptacle by
pulling on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out the
battery from the battery charger.
NOTE
Be sure to pull out the battery from the battery charger
after use, and then keep it.
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
fi
rst and second time.
This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging
the batteries 2–3 times.

Malfunction in
the battery or the
charger *3
*1 If the red lamp continues to blink even after the
charger has been attached, check to con
fi
rm that the
battery has been fully inserted.
*2 Although charging will start once the battery has
cooled down even when left in situ, the best practice
is to remove the battery and allow it to cool down in a
shaded, well-ventilated location before charging.
*3
○
Fully insert the battery.
○
Check to con
fi
rm that no foreign matter is stuck to the
battery mount or terminals.
<If charging takes a long time>
○
Charging will take longer at extremely low ambient
temperatures. Charge the battery in a warm location
(such as indoors).
○
Do not block the air vent. Otherwise the interior will
overheat, reducing the charger’s performance.
○
If the cooling fan is not operating, contact a
metabo HPT Authorized Service Center for repairs.
