(3) Regarding recharging time
Table 3 shows the recharging time required according to the type of
battery.

Battery
BSL1830
NOTE
The recharging time may vary according to the ambient temperature.
4. Disconnect the charger's power cord from the receptacle.
5. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use, and then keep
it.
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 fi rst 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
battery has just been used, the pilot lamp of the charger lights for
1 second, does not light for 0.5 seconds (off for 0.5 seconds). In
such a case, fi rst let the battery cool, then start charging.
