Load tester for checking caravans

Assuming that there is a problem  (the OP hasn't come back to explain) and it's percieved as a lack of battery capacity then most caravan battery lockers wont accomodate a battery much bigger than 110a/h. Even then, some might need a low profile battery (Bailey's with underfloor battery compartments for instance)

My 110a/h Numax battery is now nine years old and will still happily move our 1650kg caravan aound 75 metres. It will move it further but I dont usually have a need to go any further so haven't tried to see how far it will actually go.

Although, that said,  a few years ago we shifted our van about 150 metres to another pitch without any effort using the mover, rather than hitching it up to the car

We have had the same movers for nearly 20 years now. I fitted them and maintain them. The spare parts are available. However for continuing use without loads of maintenance I wouldn't use them for long distances. I really don't think they are designed for it. It's only my thoughts though.

The problem with batteries is letting them discharge over the winter. It's a challenge to maintain them in storage if the caravan is drawing power - alarm, tracker etc. A simple voltage test without a load would give you an indication of how well the battery is doing.

We had a 1991 lightweight caravan with no power usage when in storage and it could go all winter with no charging.

We now have a big twin-axle caravan, with a tracker and alarm, and have found the hard way that the battery needs charged once a month in the winter. A 90 amp hour battery is plenty to activate the motor mover, as long as the battery has been kept in good condition, and is reasonably well charged.
