(2) Regarding the temperatures and charging time of the rechargeable battery
The temperatures and charging time will become as shown in Table 4.

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
7. Disconnect the charger's power cord from the
receptacle.
8. 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 rechargeable 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
charge indicator lamp of the 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 charge indicator lamp fl ickers (at 0.2-second
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 UC18YSL3
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.
