Best to isolate one of them, the battery charger would be my first guess. Often there is a 'kettle' type plug powering it that can be fairly easily removed.

As previously asked what is the Battery state. If totally dead after standing a long time this can cause the charger to trip as it is acting as a dead short. If so replace the leisure Battery. But if the charger and fridge are totally disconnected suggests there is a faulty MCB or a fault in the consumer unit.

A flat battery shouldn't cause an MCB to trip.
If everything everything is disconnected and unplugged then it is possible that there is a fault on the wiring.
