Power it up!
The A7 finds itself in a niche segment of the market with very few competitors to speak of. It is heavily laden with luxury fitment that requires an uninterrupted supply of power. When the car battery reaches the end of its lifespan, you will need to change it in order to keep all those gadgets on the go.

You can tackle this task right at home with just a few tools and about 15 minutes.
You will need:
- Replacement battery of correct frame size and amperage
- 10mm Spanner
Let's get started!
1. Open the boot.
2. Lift the boot floor up by the handle and clip it to the underside of the deck lid with the built-in clip.
3. Lift out the spare wheel cover.
4. Remove the spare wheel retaining nut and remove the spare. (If equipped)
5. Locate the battery.
6. Loosen the nuts with the 10mm spanner and remove the bracket
7. Use the 10mm spanner to remove the negative terminal.
8. Use the 10mm spanner again to remove the positive terminal.
9. Remove the battery.
10. Install the new battery and replace all the terminals and brackets in reverse order.
The battery management function within the onboard computer needs to be reset so that the car knows that there is a new battery installed to ensure proper charge management. Without the use of a battery saver, you will lose all vehicle presets and data in the infotainment and trip computer, so a battery saver is recommended.
