Vantage Battery Replacement DIY Guide

This shouldn't be a difficult job, but... packaging. What makes it difficult is that you're working behind the seat (which is not a comfortable place to be), you're likely to have a trim piece in the way of the sliding brackets (I hate them for this), and the battery is super heavy (over 53 lbs!).
Needed
New battery
T-30 torx bit
10mm socket
13mm socket
Long extension
Ratchet
Philips screwdriver
About an hour
Torque Ratings
Battery clamp: 9 Nm. (7 lb/ft)
Battery terminals: 9 Nm. (7 lb/ft)
Step 1
Move the right-hand seat all the way forward. In the US, this is the passenger seat. In the UK, this is the driver seat.
Step 2
Remove the parcel shelf from behind the seats and the padding from on top and behind the battery.
Step 3
Remove the Philips-head screws along the aluminum bar, then remove the bar itself. You can now pull the vertical piece of carpet away from the battery and have plenty of room to work around it.
Step 4
Use the ratchet, long extension, and 10mm socket to remove the 2 bolts holding the U-shaped bracket that goes over the top of the battery.
Step 5
Use the T-30 Torx bit to loosen the 4 bolts on the two sliding clamps. The bolts do not come all the way out of the sliding clamps. They just need to be loosened enough to let the brackets slide freely. Remove the sliding brackets by pushing them all the way to the side.
Note: The carpeted trim piece to the left of the battery might be in the way. You'll have to loosen it, remove it, or simply pull it out of the way to get the brackets off. This might be difficult. Some people (myself included) cut a small notch into the carpet to allow clearance of the sliding bracket. If the notch is small enough, it will be completely hidden by the vertical carpet that sits in front of the battery.
Step 6
Remove the vent tube.
Step 7
Use the 13mm socket to loosen the nut on the ground terminal and then pull the cable away from the battery, then do the same for the positive cable.
Step 8
Remove the battery. Be careful, it’s heavy!
Step 9
Follow the steps above in reverse order to install the new battery.
And that’s it!
