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

Charging time (At 20°C)
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 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.
