TIP
Even if charging starts normally, charging might be suspended to
protect the battery if the battery temperature or ambient tempera-
ture becomes too high or too low. In this case, the battery may not
have sufficiently charged. Check the battery's residual capacity and
recharge if necessary.

7.6 Charging time guidelines

Although charging time varies depending on residual battery capa-
Charging
finish city and external temperature, if the battery has been exhausted,
it generally takes approximately 4 hours until one battery capacity
indicator lamp flashes.
If the battery pack enters standby mode while charging, charging
time will increase by an equal amount.
* If charging after a long period of disuse, the charging time will be
lengthened depending on the battery status. However, note that if
the battery capacity indicator lamps do not flash in fault pattern
(see point 7.5 on page 24), there is no malfunction.
