I have a 200 Series with dual starter batteries, which were replaced last August. It also has a deep cycle auxiliary under the bonnet fed by an ARB dual battery kit plus a 200 watt solar panel on the roof.
It's been four days since it was last driven and I came out this morning to find all three batteries flat as a tack. The starters were showing 5 volts and the auxiliary 2.5 volts. The solar regulator is showing nothing; it was dark.
I put it onto a charger for six hours and got the starters up to 12 volts. I didn't want to run a cable out across the public footpath, which sees a lot of traffic. So I used the solar powered inverter on the Glamper, which showed the van batteries at 100% just now.
Then I put a battery jump pack on and switched the charger over to START mode. It started first go and the plan is to run it on a fast idle for the next couple of hours. I can't take it out on the road because it's currently parked in. It's charging at 13.6 volts instead of the usual 14.1-14.2 when the battery is a bit low.
The only explanation I can think of is that one of the starter batteries has shorted out and flattened its partner. Then the VSR on the auxiliary must have opened and flattened that too. Dunno about the solar.
So it's off to the auto sparky who sold me the batteries tomorrow morning to see what the problem is. In the meantime, I'd appreciate and opinions from wiser heads than mine.

What loads are on the batteries?

What loads are on the batteries?
No loads at the moment as the fridge is out of the vehicle. Just normal driving loads. Mind you, I have been doing a lot of short trips lately. But the solar used to power the starter batteries when the VSR opened when it was parked.
It's got me a bit flummoxed, if that's a word.

Do you have an Ultraguage fitted?

I have a Scangauge fitted but I think I know what the problem might be. I went outside just now in the dark to get something from the Glamper and saw that the interior lights in the Cruiser were on.
I recall that I turned them on in an indoor car park on Friday to read the paper while Denise went in to renew on our Vino Collapso supplies. I don't remember turning them off.
it turns out that I may be the problem after all. Which still leaves the solar.

Wouldnt be the first time a VSR [ AKA solenoid ] stuffed up . .Sparky set one up in the oldmans camper van for the Engel .after about 18 mths it failed to switch .... the second battery wasnt getting charged ..
Replaced the VSR and it lasted about 2.5 years .. Went to a marine manual switch after that and never had another problem .

Ah, the old "interior light flattening the battery trick"...third time this week...(apologies to Agent 86) ;D ;D
Had a 12v flouro in the back of my old XB pv years ago.
The switch was on but the tube was dead. Didn't know what was causing the battery to run down.
Finally worked it out, but not until after I'd replaced a perfectly good battery.... ::)
:cheers: :cheers:

there's been many a time when you come out in the morning and see the interior light on. The nervous turn of the key to get the click or the "come on you bastard, !#@*!! start!!

The 200 series has a 20 min timer on the interior lights, so you can't leave them on....unless like Keith, you turn them on manually !

Have I permanently buggered the batteries?

I’d put them on a decent charger and see how they go.

I think most modern cars have a timer...15 mins on the Pajero

I had them on a trickle charge yesterday for about 7 hours and then ran the car on a fast idle for two hours after that.
It fired up first go this morning and the auto sparky says that the starter batteries are fine. But the deep cycle auxiliary is buggered.
he is going to trouble shoot that today.
