9.3 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 capacity become too low.
• Allowing the residual battery capacity to become too low and not recharging the battery in time can
result in a total discharge. A total discharge can cause your battery irreparable damage which will void
the warranty on your battery.
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.

Action
Press the power switch on the display unit to

Charge the battery pack.
Turn the power on again.
This is not a malfunction. It is a safeguard
engaged when the temperature of the battery
pack or the drive unit is too high. Power assist will
be restored once the temperature of the battery
pack or the drive unit has decreased. Also, you
can make this less likely to occur by shifting to
a lower gear than you would usually use (for
example, by shifting from second to first gear).
During the wintertime, store the battery pack
indoors before use.
Set the display correctly.
Stop charging the battery pack.
Check to make sure the battery pack is locked
in place. If this problem still occurs with the
battery pack firmly locked in place, there may
be a loose connection in the battery pack
terminals or wires. Have an authorized dealer
inspect your bicycle.
There could be a problem inside the drive unit.
