The battery of the handlebar module can be replaced. You can use a fully charged battery for 6 to 18 months, depending on usage. The more you ride and the more you shift, the sooner the battery will need to be replaced.
You can replace the dropbar handlebar unit's button cell battery (CR1632) without removing the tape from your handlebar.
1. Loosen the twee Torx T5 screws on the dropbar handlebar unit.
2. Pry the handlebar unit from the dropbar handlebar unit using a flat-head screwdriver. If required, you can lightly squeeze the edges of the holder in the handlebar to facilitate removing the dropbar handlebar unit.
3. Fully remove the dropbar handlebar unit from the handlebar and disconnect the handlebar unit's connector.
4. Turn the dropbar handlebar unit around.
5. Disconnect the housing using the Torx T5 screwdriver.
6. Slide the battery holder out of the housing.
7. Remove the CR1632 button cell battery while fixating the electronics in it's holder.
8. Install the new CR1632 button cell battery. Place the battery correctly. Observe the + and - markings.
9. Reinstall all parts in the reverse order of removal. Pay special attention to the following:
- Ensure that the rubber seal between the battery holder and the housing is installed correctly in the groove.
- Install the connector fully up against the handlebar unit. Before continuing the installation, check that the LED blinks both when shifting up and when shifting down.
NOTE: Do not dispose of the battery in general waste! Take the discharged battery to an authorised collection point.
