This car needs the battery registered
The battery type on this car depends on its factory option. If the battery you are removing is labeled AGM or EFB, the car has a smart charging system and the new battery should be registered to it, which a shop, a dealer, or an OBD-II tool that supports registration does in minutes. Audi is one of the makes where skipping that step shortens the new battery's life.

What Group 48 means
A BCI group number describes the battery's physical size and terminal layout, not its power. It is what guarantees the battery drops into the tray and the cables reach the right posts. A Group 48 case measures roughly 278 × 175 × 190 mm. Standard-terminal layout.
Group 48 is one of the most common battery sizes on the road: it is the 1st most common of the 30 sizes across every vehicle we hold specs for, fitted to 21.7% of them. Every store stocks it, and you will never struggle to find one.
This car was built with Group 48, 47 batteries depending on its factory battery option. These are different case sizes, so they do not swap for one another: match the group printed on the battery you are removing.
How many cold cranking amps?
Aim for 540 CCA at minimum. Cold cranking amps measure how much current the battery can deliver at 0°F, which is the one moment a battery is really tested. The 540-680 range reflects the different batteries fitted across this vehicle's trims and options. Going above the OEM rating is safe and does no harm - the starter draws what it needs and no more, so a higher-CCA battery is not "too strong" for the car. It is worth paying for if you park outside in a cold climate, and largely wasted money if you do not. Going below 540 is the one thing to avoid, because that is where hard winter starts come from.
How long it should last
The warning signs are worth knowing because they are easy to miss: cranking that sounds slower than it used to, headlights that dim at idle and brighten when you rev, or a car that starts fine every day until the first cold morning and then does not. A battery rarely warns you twice.
