8.5. The Temperature of the Lithium Ion Battery (ESB1)
during Charging
Charge the battery in an environment with a temperature of
10 to 25°C.
• To protect the battery, if the internal temperature 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 (green) will change from a flashing
to an "on" state, and charging will start automatically. (The length of the standby time varies with the conditions.)
• The battery temperature increases during charging. However, if the battery temperature rises above 45°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.
