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.
CAUTION
When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
4. Disconnect the charger's power cord from the
receptacle or cigarette lighter socket.
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.
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 UC18YML2 charger lights up green, or the
pilot lamp of UC18YFSL charger lights for 1 second,
does not light for 0.5 seconds (off for 0.5 seconds), or
the charge indicator lamp of UC18YSL3 charger lights
for 0.3 seconds, does not light for 0.3 seconds (off for 0.3
seconds). In such a case, fi rst let the battery cool, then
start charging.
○ When the pilot lamp or charge indicator 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 confi rm that the battery being charged with
charger 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.
○ Check the voltage of the in-car power source when
the pilot lamp fl ickers in green (every 0.2 seconds)
continuously. (UC18YML2)
If the voltage is 12V or lower, it indicates that the car
battery has weakened and cannot be charged.

in red (every second) even though the charger cord
or cigarette lighter connecting plug is connected to
the power, it indicates that the protection circuit of the
charger may be activated.
Remove the cord or plug from the power and then
connect it again after 30 seconds or so. If this does not
cause the pilot lamp or charge indicator lamp to blink
in red (every second), please take the charger to the
Hitachi Authorized Service Center.
