BATTERY PACK AND CHARGING PROCEDURE

Charging time guidelines

Although charging time varies depending on residual bat-

tery capacity and external temperature, if the battery has

been exhausted, it generally takes approximately 4 hours

(500 Wh)/3.5 hours (400 Wh) until one battery capacity in-

dicator 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 “Reading the charging

status”), there is no malfunction.

TIP

For example, even if normal charging is started, if the battery temperature or the surrounding tem-

perature is too high or too low, the charging may be extended or charging may be stopped without

the battery being charged sufficiently in order to protect the battery.
