Hi all,

Im looking to change my leisure batteries on T6 calif 2016. (I have don't check what model are installed currently)

Do I need to code them into vcds ?
Can I upgrade to 100ah for exemple without risk for battery charger?

Some advices ?

I saw only one battery information into vcds so i suppose it is starting battery:
;068 JCB 1111111111

Thx a lot,
