Duralast Platinum H8-AGM battery, or any other larger than OEM size battery.
Auto zone lists this battery as a fit for a 2015 Passat. It does fit after quite a bit of work to make it fit since the H8-AGM is just under 10cm (4") longer, the width is the same. I did not try to fit the silly battery cover back on the new battery, it's too short anyway. This battery weighs 65 lbs.
In order to fit the battery the complete air filter box needs to be removed. The battery tray also needs to be removed and a high lip at the firewall end needs to be sawn off. Also some other high points sticking up on the battery tray need to be sawn off. There is also a mount for the air filter box which needs to have a rib removed to allow the battery to sit flat on the tray. Lastly on the the battery hold down bracket the two short tabs need a bit of bending to make it fit. I used two vise grips to do that.
Next is to re-install the battery tray. Now it's time to position the new battery, I used a medium screwdriver between the lip on the tray to force the battery into place and then lock it down with the clamp. Then with a with a lot of forcing get the air filter box back into place and the new battery can be connected with the original cables, they just fit. Positive first, negative last.
Tools required, a # 20 torx driver. A 10mm and a 13mm socket and a 6mm Allen wrench. I also used the medium blade screwdriver to spread the battery clamps.
Total time for me was just under three hours. But I'm not a spring chicken anymore and it was hotter than h*ll. Sorry no pictures, I was too busy.
