(1) Pilot lamp indication
The indications of the pilot lamp will be as shown
in Table 1, according to the condition of the charger
or the rechargeable battery.

NOTE: When standby for cooling battery, UC18YRL cools the overheated battery by cooling fan.
(2) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in the table below, and batteries that have
become hot should be cooled for a while before
being recharged.

4. Disconnect the charger's power cord from the
receptacle
5. Hold the charger firmly 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 the charger lights up
green. In such a case, first let the battery cool, then
start charging.
When the pilot lamp flickers in red quickly (at 0.2-
second intervals), check for and take out any foreign
objects in the charger's battery installation hole. 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 confirm that the battery being charged
with UC18YRL 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.
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 first
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.
