17.3.2 Charging the battery for Shimano
electronic gearshifts
The rechargeable battery charge level of the
electronic gearshift is also visible on the dis-
play. When the charge state is low (thus when
only one rechargeable battery bar is shown),
the rechargeable battery must be recharged.
Figure 15: Alfine Di2 electronic gearshift battery
For this purpose, the rechargeable battery is
removed as follows: the flap on the side is
opened and the push button is pressed-in (fig-
ure 16). Now the rechargeable battery can be
pulled out along the retaining rail and charged
using the charger included in the scope of
supply. During the charging procedure, an
orange lamp is visible (figure 17).

charging
Figure 17: Rechargeable battery and charger
The fully charged rechargeable battery (visible
on the charger when the orange lamp goes
out) is pushed back along the retaining rail until
you can feel a slight resistance. When closing
the flap on the side, the rechargeable battery is
completely secured and is connected fixed.
Now the gears are ready for use again.
