Moll replacement.....doubts

[Vinci]

A while back, a very nice man from VW Assist replaced my generally accepted as defective Moll battery with a new Varta one.
Until recently, no concerns. However, in the last week or so, the van has been slightly reluctant to start....it always has, but sometimes without enthusiasm, if you know what I mean.
I popped into Simply Surf Bus to have a chat (really nice guys, came away with new wheels..see my post elsewhere), where on leaving, the van wasn’t keen. Top man and Co boss, Dan, popped my bonnet and said he thought, given my stop start, there should be an AGM battery, as in the van’s being converted. Dan rang a contact in VW who confirmed my battery was indeed the one listed for my 2017 T6 Highline 150.
Please would anyone in the know out there, throw in their view, please?

As far as I know, the starter should be AGM.

Yes, labelled with EFB.....is that the same as AGM?

Efb normally put on cars in my experience not vans they are in my opinion not upto the needs of bigger vehicles

AGM vs EFB -->

Stop/start...regen...smart Alternator... Dc-dc Charger For Leisure Battery Or Not?

So With all the talk regarding the Bluemotion thing and regen breaking and leisure batteries our T6 has finally arrived. The first thing we done was to checkout the factory fitted setup,...... Stop/start=check, Regen Braking=check, AGM starter battery=check leisure battery under passenger...

Ok, thank you, basically EFB are ok, but cheaper alternative to AGM batteries.

FWIW, the battery in my 2018 150Ps manual is an Varta EFB - I got the van at a year old and under 4K miles but I believe it’s the factory fit. The van is not used much in winter in particular and I sometimes get alarmed at how low the voltage goes and therefore stick it on charge with a CTEK MX5.0. When I had an auto electrician fit my Autowatch Ghost, I asked him to test the battery and it passed as OK. The leisure system is supposed to ensure a trickle into the starter but when there’s no sunshine.................

All the moll were efb.

All the moll were efb.

Sorry, I should have been clearer - mine is a Varta EFB. Original post now corrected.

Interesting....definitely a faulty batch of Molls then....shame VW weren’t worried about customer care.
