Long storage period (1 month or longer)
and using it again after a long storage
period
• When storing the bicycle for a long period (1 month or
longer), remove the battery pack and store it using the
following procedure.
• Decrease the residual battery capacity to where one or
two lamps are lit, and store it indoors in a cool (10 to 20
°C), dry place.
• Check the residual battery capacity once a month, and
if only one lamp is flashing, charge the battery pack for
about 10 minutes. Do not let the residual battery ca-
pacity become too low.
TIP
• If you leave the battery pack at “full charge” or “empty”,
it will deteriorate quicker.
• Due to self-discharge, the battery slowly loses its
charge during storage.
• The battery’s capacity decreases over time but proper
storage will maximize its service life.
• When using it again after a long storage period, be
sure to charge the battery pack before using it. Also, if
you are using it again after storing it for 6 months or
longer, have your bicycle inspected and maintained at
a dealer.
