It rather depends on the Ah capacity of the batteries and how you intend to charge them. If using EHU and assuming 200Ah total it will take at least two days. Three to be certain.

No way
'Fraid so. You need to put around 240Ah back (allowing for battery inefficiencies and losses). Unless the charger is smart enough to provide a boost at an appropriate point during the charge cycle the batteries will only accept an average of around 4A. 240/4 = 60 hours. And that assumes the van isn't in use whilst charging.

Well, you are correct. I was thinking that the OP could surely not have used that much and if he did then the batteries would now be shot to pieces
But…………….the alternator will charge at a MUCH higher rate than mains charger
Also depends on whether you have gel, AGM or standard lead-acid batteries. The former two take much longer to charge than lead-acid.
Making some assumptions, if you have 2 x 110 Ah batteries or similar, and have used about half the charge in two days, then mains charging will take about 24 hours or a bit more if you have lead-acid. For gel, I would double that. These are only 'best guesses'.
