(2) Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are as
shown in the Table 3, and batteries that have become
hot should be cooled for a while before being recharged.

32°F – 122°F
(0°C – 50°C)
(3) Regarding recharging time (At 68°F (20°C))
Depending on the combination of the charger and
batteries, the recharging time will become as shown
in Table 4.

UC18YKSL
BSL1815S
Approx. 35 min.
BSL1825
Approx. 75 min.
NOTE
The charging time may vary according to temperature
and power source voltage.
4. Disconnect battery charger from the receptacle.
CAUTION
Do not pull the plug out of the receptacle by
pulling on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out the
battery from the battery charger.
NOTE
After operation, pull out batteries from the charger
fi
rst, and then keep the batteries properly.
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
●
When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
●
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 for 1 second, does not light for
0.5 seconds (o
ff
for 0.5 seconds). In such a case,
fi
rst let the battery cool, then start charging.
●
When the pilot lamp
fl
ickers (at 0.2-second
intervals), check for and take out any foreign
objects in the charger’s battery connector.
