NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
<UC18YML2>
Especially, using a DC 12V in-car power source may
require longer recharging time at high temperatures.
4. Disconnect the charger’s power cord from the
receptacle or cigarette lighter socket.
5. Hold the charger

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 up green or 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.
