Batteries when caravan is not being used.

If your battery charger is a 3 stage or multi stage one that goes into float mode then you can leave it the van connected to 240 all the time provided power is readily available.
If your battery is a wet cell job then you will have to check the electrolyte levels occasionally as one should always do.
If your battery is an AGM or Gel cell type then no checking is warranted.
Battery's love to be kept fully charged and indeed last longer that way.
Whenever my van is stowed at home it is always connected to 240v with the multi stage charger looking after the battery and the battery is still going strong after 4 years.

Micheal,
I leave lead plugged into a time clock that I set to come on for 1 hour a couple of times a week, this keeps the battery charged no problems at all. I set it to come on at around 4am so the battery charger is running in the coolest part of the day.

I do the same with my old Troopcarrier and the 3 stage charger doesn't even get hot enough to run the cooling fan.

Have a good one

The electrogurus here have always said a full battery is a good battery, so I dutifully connect the van to 240V and charge mine about every fortnight, via the inbuilt multi-stage 240V charger.... that is when the solar panels are not working while under the van cover (but hey - that van cover even lets an amp or two's worth of light through the fabric !).

The most convienient way to keep it charged is to buy a cheap solar panel like THIS & mount on your roof. For simplicity fit an Anderson plug to connect it up rather than the clamps.
(Not endorsing the quality of that particular product just the concept)

Michael Hi

The best way to keep your battery is fully charged, by the looks of your Van, I would say it has the new type 3 stage charger, if it has and it is easy to plug into 240 volts do so and leave it on, it will charge it and keep it cahrged.

The battery charger will manage the battery for you and will be ready for use.

the other way is as mentioned Solar is another way of keeping it fully charged and can be used when away on a trip,

Make a list of all the things in your caravan,

Battery - make size model
Charger - make size model
is it solar ready

and I'm sure we (ExplorOz people) will try and pass on some knowledge.

Regards

Richard

I'm still learning also...

Mine in the van is an AGM. Drops from about 12.85 to 12.8 over about two months. I hook up to 240v run the 3 stage on board charger about every 2months.

Whatever you do don't do what old dumbo me did and left the fridge fan running and then proceeded to unplug the 240v power to move the van and forgot to plug it back in for about a week or so. Battery voltage down to 10.2v and looks like it may be stuffed.(:-(((((((

My opinion, if you have some type of reasonable quality smart charger plug it in and leave it on.

Cheers Pop

Just to be different...our van sits for 10-11 months with the battery(sealed wet cell) in it , I hook it up only a couple of times in that time to 240v and the 3amp charger in the van...the battery is 7 yrs old and I had it tested earlier this year by my local battery supplier....nothing at all wrong with it..cheers

We have our van stored in a large, commercail storage "carport" when we are not using it. We do not have solar, or access to 240v there. We remove the main battery and the breakaway battery and keep them charged up in our garage.

When we are going away in the van the first thing we have to do is put the batteries back in the van.

Taking the main battery out and replacing it is relatively easy. Breakaway is painful - poorly placed at the back of a cupboard at floor level, and the whole unit has to be taken off the wall (4 large screws) before the unit can be opened to access the battery. I understand the latest units have been redesigned for easier access for removing the battery - too late for us!
