Why Is My Caravan Battery Not Charging. Use of a generator with the caravans charger in use is not a good idea as they can damage the caravan charger if a surge occurs. If above okay its one of two things 1 batteries not getting charged when hooked up to mains faulty charger or constant drain on circuit light somewhere water pump on too much etc.
If the panel is mounted on the roof of a caravan and is operating during the winter months in southern Australia it could easily take three days or more to fully recharge that battery. So if you have a 20A charger in the van the DC charger in the vehicle will be supplying the charge to the van and not charging the auxiliary battery in the vehicle. These have a long time lag 24 hours plus between heavy loads and subsequent voltage.

If it is you should see the battery or alternator light on it indicates that the alternator is not creating the necessary voltage to charge the battery.

Ideally you must check your caravan battery charge every two months and avoid running it flat off charge as it damages the battery performance too.
