Charging Di2 how to remove end cap
Quote | Reply
I need to charge my Di2 on a Tarmac and the battery is inside the right handlebar. How do you remove the end cap to access the battery?

I checked the owners manual and also YouTube and could not find anything.

You charge Di2 through a plug in the Junction A component. The Junction A is either a little rectangular thing by the stem with several wires going into it. Or it is an end cap on your handlebars with an LED and a small button. If the latter, the port is under a little plastic cap under the button.

Found it, thank you. It’s very small and hard to see.

Makes it easy to charge though.

... and if you have a Windows PC you can also use that port to connect the bike to a computer and change settings ;-)

One more question. How do I know it is fully charged? Do I hold down the button until the lights flash and then make sure it shows green?

Hold down any shifter button for ~0.5 sec. Some people hold both shifter buttons (on road levers).
Also - the charging LED (on the charger itself) will switch off ;)

That is really helpful information in the attachment. Thanks.

It should have come with the owner's manual. That would have made things much easier.
