(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.
(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 3.
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 operation, pull out batteries from the charger
first, 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 (off for
0.5 seconds). In such a case, first let the battery
cool, then start charging.
●
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC18YGSL is taken out, wait for a minimum
of 3 seconds before reinserting it to continue
charging. If the battery is reinserted within 3
seconds, the battery may not be properly charged.
