Thanks I'll have a closer look at my OBD11 then. Maybe it times out and switches off after 20 minutes like other systems.
I leave it plugged in but I'm pretty sure it does have a slight drain. If I need to leave the van for a week or two such as going on holiday only then do I unplug it
@Drive Wayne @drinfinity @Dundee_Kev @Dellmassive (and anybody else who's interested!). I've just had an email from Head of Support @ Carista with the following:
'Thanks for using Carista! The ECU of your car doesn't require the battery technology/capacity to be entered in order to register the new battery, that's the reason why it's not listed as an option.'

Cheers guys. £6.59 more spent for a really useful app that I didn’t need yesterday. 
I'm sure it does have a slight drain leaving stuff plugged in to OBD ....either that or my battery isn't quite as good as it used to be
I'm afraid they never sleep - found in my notes the following, never fell assleep.
OBDeleven (1st gen) @12.8V. Average (rms) consumption 32 mA.
OBDeleven nextGen @12.8V. Average (rms) consumption 22 mA.
Bought yesterday but arrived and fitted this morning - a set of LED Interior bulbs (front and rear) from THQ. One of the map lights in the front died on Thursday so I used the opportunity to change the whole lot. All cool white, no flickering and much better that the old yellow ones. Pic for comparison purposes.
I'm leaving my Evo plugged in, in the hope that the Ablemail will look after the SB.
As I peered through the vans front window at midnight last night there was no sign of lights being on in the footwell.
Drink! To restock the bar before all the family arrive!!
Not sure if it makes a difference if you have a smart alternotor or but I think they are fobbing you off. It needs to know what type of battery you have installed so that it can manage the charging correctly. AGM and EFB batteries require different charging voltages etc. so if you change the battery type the ecu needs to know.
So it would seem that VCDS is able to tell the van that there's a new AGM battery in place but Carista can't (because Carista deem it unnecessary). I guess the acid test would be if anybody has actually changed from EFB to AGM and NOT told the van that new a battery type has been used as a replacement (ie. perhaps a Carista user!) and had problems or otherwise as a consequence. From comments above, it would seem that there might be at least one person who made the change with no ill effects so far. Speaking for myself, I suspect it's just too early to tell as it's only been a week and I've only driven the van once since the switch.
Anybody else?
Did mine about a month or so back. No difference whatsoever, other than it now starts effortlessly when it was clearly an issue before.
Not sure what else anyone can expect tbh.
It’s holding good charge according to Carista when I check it after a few days of not driving it. This was not the case with the old battery.

OBD11 seems to be able to, haven't tried it, just for info.
