NOTE
The recharging time may vary according to the ambient temperature.
In addition, the charge time becomes signi
fi
cantly long in a low temperature environment,
but this is not abnormal.
4. Disconnect the charger’s power cord from the receptacle.
5. Hold the charger
fi
rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the 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.
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.
(2) Avoid recharging at high temperatures.
A battery will be hot immediately after use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate, and the battery life will be shortened.
Leave the battery and recharge it after it has cooled for a while.
CAUTION
○
If the battery is charged while it is heated because it has been left for a long time in
a location subject to direct sunlight or because the battery has just been used, the
pilot lamp of the charger lights for 1 second, does not light for 0.5 seconds (o
ff
for
0.5 seconds). In such a case,
fi
rst let the battery cool, then start charging.
○
When the pilot lamp
fl
ickers in red (at 0.2
-
seconds intervals), check for and take
out any foreign objects in the charger’s battery connector. If there are no foreign
objects, it is probable that the battery or charger is malfunctioning. Take it to your
authorized Service Center.
○
Since the built
-
in micro computer takes about 3 seconds to con
fi
rm that the battery
being charged with UC12SL is taken out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is reinserted within 3 seconds, the
battery may not be properly charged.
