NOTE: When standby for cooling battery, UC18YMRL / UC18YRL cools the overheated battery by cooling fan.
(However, the cooling fan does not function when charging the battery with a DC 12V in-car power source.)
(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.

(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

Battery
BCL1430, EBM1830 Approx. 45 / 120 min.
BCL1440, BCL1840 Approx. 60 / 160 min.
NOTE:
The recharging time may vary according to the
ambient temperature and power source voltage.
<UC18YMRL>
Especially, using a DC 12V in-car power source may
require longer recharging time at high temperatures.

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.
4. Disconnect the charger's power cord from the
receptacle or cigarette lighter socket
5. Hold the charger firmly 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 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,
