4. Battery (EB1814SL, EB1820L, BCH1820)
(For DS18DVF3)
Optional accessories are subject to change without
notice.
APPLICATIONS
䡬 Driving and removing of machine screws, wood
screws, tapping screws, etc.
䡬 Drilling of various metals.
䡬 Drilling of various woods.
BATTERY REMOVAL/INSTALLATION
1. Battery removal
Hold the handle tightly and push the battery latch
(1 pc. or 2 pcs.) to remove the battery (see Figs.
1 and 2).
CAUTION
Never short-circuit the battery.
2. Battery installation
Insert the battery while observing its polarities (see
Fig. 2).
CHARGING
〈UC9SD/UC12SD
〉
Before using the driver drill, charge the battery as
follows.
1. Insert the battery into the charger
Insert the battery firmly while observing its direction,
until it contacts the bottom of the charger (See Fig.
3).
CAUTION
The UC9SD and UC12SD models are the
exclusively designed charger. These cannot
charge batteries except the specified batteries.
It is possible to insert the batteries other than
the specified into the charger and some of them
may light up the pilot lamps. However, you are
requested to exercise utmost caution not to
charge batteries other than specified ones
because these can not only be charged but also
such actions can result in the malfuntion of
chargers.
2. Connect the charger power cord to the receptacle
Connecting the power cord will turn on the charger
(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.
About 60 minutes is required to fully charge the
battery at a temperature of about 20°C. 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.
3. Disconnect the charger power cord from the
receptacle
4. Hold the charger firmly and pull out the battery
NOTE
After charging, 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.

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 1.
