If the Tow Tuff TMD-3500ET dolly only works when plugged in despite the batteries being charged, possible issues include:

1. Faulty battery not holding charge.
2. Damaged or loose battery connections.
3. Battery not properly installed.
4. Power switch or internal wiring issue preventing battery power from reaching the motor.

Check the battery status, cable connections, and power switch as initial steps.
