WARNING
O
Be sure to store the disconnected battery with the protective cap on it.
Exposed contacts can cause short circuits and lead to a fire or battery rupture.
TIP
If you are unable to charge the battery
Refer to “14. Troubleshooting”.
(3) Suitable temperature for charging
Charge the battery in an environment with a
temperature of 10 to 25°C.
• To protect the battery, if the internal tem-
perature of the battery is under 0°C or over
40°C, charging does not start. Instead, it
enters a standby mode. During this time,
the charge lamp (green) flashes.
While in standby mode, when the battery
reaches an appropriate temperature, the
charge lamp will change from a flashing to
an “on” state, and charging will start auto-
matically. (The length of the standby time
varies with conditions.)
• The battery temperature increases during charging. However, if the battery temper-
ature rises above 50°C, the power for the charger will turn off to protect the battery.
Since charging has not ended, it is necessary to charge again after the battery
temperature has decreased.
Charging a battery immediately after travel, or charging a new battery is likely to
cause its temperature to increase, which increases the likelihood of the charger
stopping charging before completion.
• A cooling fan operates automatically if the charger temperature increases during
charging.
While charging, do not block the intake and exhaust vents of the charger.
