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.
Rechargeable batteries

Regarding recharging time
Table 4 shows the recharging time required according to the type of battery.
Battery
voltage
10.8 V
NOTE: The recharging time may vary according to the ambient temperature and the
power supply 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.
CAUTION:
When the battery charger has been continuously 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.
When the pilot lamp flickers (at 0.2-second intervals), check for and take out any foreign
objects in the charger's battery installation hole. If there are no foreign objects, it is
probable that the battery or charger is malfunctioning. Take it to your authorized
Service Center.
If the battery charger does not work while the battery is mounted correctly, it is
probable that the battery or charger is malfunctioning. Take it to your authorized
Service Center.
