(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.
Table 2 Recharging ranges of batteries

Temperatures at which the battery can be
recharged
BSL1830 0°C – 40°C
(3) Regarding recharging time
Depending on the combination of the charger and batteries, the charging
time will become as shown in Table 3.

NOTE
The charging time may vary according to temperature and power source
voltage.
4. Disconnect the charger’s power cord from the receptacle.

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.
