Hello,
I have a 2002 Bailey 420 and would like to know what size battery will fit in to my caravan.
Regards.
The first thing you should do is to measure your battery compartment to find the dimensions. Take into account the conection leads when measuring the height. You will then know what size battery can fit in your compartment. Once you have these measurements, go to your local dealer and have a look at the batteries they have on sale. You shoud buy a battery with a high Ah. The higher the Ah (Amphere hours), the longer it will last between charging.
