Written by Jonas Frank / Fact-checked by Nova Scarlett

Your RV battery might not be charging due to a range of issues including a malfunctioning alternator, a faulty converter, or problems with the charging system wiring and connections. It could also be due to a depleted battery that is no longer able to hold a charge.

Driving your camper can often recharge the battery, but if this isn’t happening, the alternator or the wiring that connects it to the battery could be at fault. Similarly, if the battery isn’t charging while connected to shore power, it’s often a sign that the converter, responsible for transforming AC power to DC to charge the battery, is malfunctioning or has failed. You can identify a faulty converter by checking if it’s overheating, making unusual noises, or if the RV lights are flickering.

RV batteries might also face charging issues when powered by a generator. Ensuring the generator is in good working condition and the connections to the battery are secure can often resolve this issue. For owners of Forest River RVs, it’s not uncommon to face battery charging issues, and consulting the specific model’s manual or seeking professional help can offer solutions.
