S2 NOT CHARGING
​
Hi everyone,
I have a SUPER73 S2 that is currently showing 9% battery (about 5 km remaining) in the SUPER73 app, and I’m having trouble figuring out whether it is actually charging.
The strange thing is that the charger LED stays red in all three situations:
Charger plugged into the wall, but NOT connected to the bike → 🔴 red
Charger plugged into the wall AND connected to the bike → 🔴 red
Charger connected to the bike, but NOT plugged into the wall → 🔴 red
I’ve checked the charging connector and it appears to be properly connected to the bike. The battery is also switched on while charging.
I left it connected for a while, but the app still shows 9%.
Is this normal behavior for the S2 charger?
Could the charger LED being red even when it isn't plugged into the wall indicate a faulty charger, or could the problem be the battery/charging port?
I’ve attached photos of the charger, connector, and charging port.
Any advice from other S2 owners would be greatly appreciated. Thanks!
If anyone knows a way to test whether the charger is actually delivering power without opening the battery, I’d appreciate that too.
