(2) Regarding the temperatures of the rechargeable

battery
The temperatures for rechargeable batteries are as
shown in 

Table 2

, and batteries that have become

hot should be cooled for a while before being
recharged.

Table 2

 Recharging ranges of batteries

(3) Regarding recharging time

Depending on the combination of the charger and
batteries, the charging time will become as shown
in 

Table 3

.

CHARGING

<UC18YGL, UC18YRL, UC18YFL>
Before using the driver drill, charge the battery as
follows.

1. Connect the charger’s power cord to the receptacle.

When connecting the plug of the charger to a
receptacle, the charge status lamp  will blink in red.
(At 1-second intervals).

2. Insert the battery into the charger.

Firmly insert the battery into the charger till it
contacts the bottom of the charger and checking
the polarities as shown in 

Fig. 3

.

CAUTION:

䡬

If the batteries are inserted in the reverse direction,
not only recharging will become impossible, but it
may also cause problems in the charger such as
a deformed recharging terminal.

3. Charging

When inserting a battery in the charger, the charge
status lamp will light up continuously in red.
When the battery becomes fully recharged, the
charge status lamp will blink in red. (At 1-second
intervals.) (See 

Table 1

)

(1) Lamp indication

The indications of the lamp will be as shown in

Table 1

, according to the condition of the charger

or the rechargeable battery.

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

䡬

When the battery charger has been continuously
used, the battery charger will be heated, thus
