Because I am in India I primarily ride using Zwift and Trainer road (TR). I spent a long period of time using TR and didn't shift or think to charge my Di2. When I went back to Zwift my Di2 was dead. When I went to charge it I got nothing. The charging unit is not even giving any lights (internal battery charger). When plugged into the computer with the charger I am able to connect to the system with E-Tube but it cannot find the battery.
Assuming the battery was dead I ordered a new battery. It just came in and I plugged it in. Everything seemed to work fine for about 15 minutes until everything went dead again with the same issues.
The charger doesn't seem to be the problem as it will connect to the computer and detect all the shifters and derailleurs but I ordered another one just in case.
I'm at a complete loss on where to go with this. Does anyone know if this is a common issue or what other troubleshooting I can do?
