I did a how to guide on the mK7 forum here:-

To fit the new battery:- Hopefully you will have pre-bent/creased the folds correctly in the new fabric battery insulation cover, & have it fitted over the new bigger battery. You will have realised these batteries are heavy (20kg circa), so carefully place the battery in the front part of the tray. Now connect the + first & then the – cables to the battery & partly tighten the clamps up (enough to hold in place). Now slide the battery back into the rear right hand corner (nearest the suspension turret top). This is because there is a hold down lip in the rear & right hand side of the battery tray which helps to hold the battery in place! Now refit the battery clamping plate & the clamping plate bolt, & use a torque setting of 15Nm (11lbft). Then for the battery terminal clamp nuts a torque setting of 6Nm (4.4lbft). Now remove the 12V supply & replace the black plastic cover for the + cable terminal (Item No.3), & black plastic flap over the “-“ (Item No.5).
VCDS coding required:-
From the Main screen:-
Select Control Module [Select]
[19-CAN Gateway]
Advanced Functions screen:-
[Adaptions-10]
New value choice screen:-
Change the following four channels, inputting the relevant data about the new battery.
IDE03256-MAS06105-Battery adaptation-Rated battery capacity,
IDE03256-MAS06106-Battery adaptation-Battery technology,
IDE03256-MAS06107-Battery adaptation-Battery manufacturer,
IDE03256-MAS06108-Battery adaptation-Battery Serial Number,
Battery BEM codes are now redundant with the above separate channels. The most important channels are, Rated battery capacity, Battery technology, & Battery Serial Number. For the Battery Serial Number, just change one digit of the old one. This channel tells the BCM that a new battery has been installed & to relearn the new battery & forget any “learnt values” for the old battery!
