My Caravan battery will not hold it's charge and goes flat in hours?

My caravan battery will not hold a charge. There is never enough power to work the mover and the battery goes flat within an hour with only the radio on, even after a charge via the caravan mains socket of a couple of days. When plugged into the mains the caravan works fine (with the exception of the mover)I don't think it's the battery as I have two and both have the same problem and one is quite new.

Vehicles, Caravans/Motorhomes Battery Charge Power

In addition to the last answer, if you have a test meter you could make sure everything is switched off, disconnect the + (red) lead on the battery, then connect your meter to battery and + lead with the meter set to Amps. This will indicate if you have some discharge and the problem then would be to locate where it is!

As you say you have 2 and both have same fault at the risk of stating the obvious......they are both leisure batteries and not car batteries and have been checked to make sure all cells are fine? If above okay it's 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. Try charging "best" battery independent of caravan and see what happens when you put it back.
