Question: We too have battery issues. We are parked at a full hookup site. We purchased our 2004 Sprinter used. When we leave it plugged in to the electric at the RV site, we come back to NO power and empty batteries. Any thoughts on what could be wrong?
Answer: With the limited information, here are a few thoughts. It sounds like maybe the circuit breakers are tripping. Perhaps you have too many electrical draws causing the circuit breakers to trip.
Additionally, your batteries may be bad. It’s difficult to guess, since we don’t know what you have plugged in/running that might be drawing down your batteries. If possible, stay in the RV to see what happens while you are there. You can also read other posts on our site about troubleshooting battery issues.
