12V battery new chemistry is EFB+ , if will need 12V battery adaptation and change in 12V battery coding side.

In my Golf, the adaptation is relatively simple - just use VCDS or OBDeleven to change the battery brand, model number, capacity and chemistry. Is it the same on MEB cars, or is it more complicated?

I know lots of folks who run AGM batteries on their Golfs, and I imagine if the coding is the same, we could do that on the ID.4 as well?

Yes quite simple if you are familiar with obdeleven
