RV Batteries Not Charging
How to think about battery charging issues, whether on shore power, generator, or tow vehicle.
Converter Output
The converter charges the battery when plugged in. Use a multimeter to check voltage at the battery. It should be 13.2V+ when plugged in. If it's 12.4V or less, the converter isn't charging.
Disconnect Switch
Ensure your Battery Disconnect (Store/Use) switch is in the 'Use' or 'On' position. If disconnected, the charger cannot reach the batteries.
Can't fix it yourself?
Don't let a mechanical issue ruin your trip. Connect with vetted mobile RV technicians who can come to your location and get you back on the road.
