(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown
in Table 4.

NOTE
The charging time may vary according to
temperature and power source voltage.
4. Disconnect the charger's power cord from the
receptacle
5. Hold the charger firmly and pull out the battery
NOTE
After operation, pull out batteries from the charger
first, and then keep the batteries properly.
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.
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 batetery 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 (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 UC24YFA and UC24YJ are 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.
〈 UC18YG 〉
Before using the power tool, charge the battery as
follows.
1. Connect the charger power cord to the receptacle
Connecting the power cord will turn on the charger.
2. Insert the battery into the charger
Insert the battery firmly while observing its direction,
until it contacts the bottom of the charger (See
Fig. 12) (the pilot lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the
power cord from the receptacle and check the
battery mounting condition.
(1) Regarding the temperatures of the rechargeable battery
The temperatures for rechargeable batteries are as
shown in Table 5.

The pilot lamp goes off to indicate that the battery
is fully charged.
The battery charging time becomes longer when a
temperature is low or the voltage of the power
source is too low.
When the pilot lamp does not go off even if more
than 120 minutes have elapsed after starting of the
charging, stop the charging and contact your
HITACHI AUTHORIZED SERVICE CENTER.
CAUTION
If the battery is heated due to direct sunlight,
etc., just after operation, the charger pilot lamp
may not light up. At that time, cool the battery
first, then start charging.
