Am I looking at the right replacement batteries?

[Sian]

I need to replace both my batteries. For the sake of piece of mind I want to fit what VW originally put in.

I am struggling to find the varta LA70 - 840070076.

This is the battery I am looking at which is same brand, same dimensions but 75ah - would this be a close enough like for like replacement?

Thanks for your help in advance.

It doesn't matter as long as they are both the same type/size.
