With Start-Stop: versions with automatic engine stop-start, or that leave the factory with an EFB or AGM battery. Ah = capacity; A = cold cranking current (EN standard); + right/+ left = side of the positive terminal. Under each engine you will find its engine codes, handy for identifying your version.

## What you should know about the Audi A3 8V

This page covers A3 (8V1, 8VK), A3 Sportback (8VA, 8VF), A3 Limousine (8VS, 8VM) and A3 Convertible (8V7, 8VE): 25 engines in the table, petrol (15), diesel (7), gas (CNG/LPG) (2) and hybrid (1). Most engines have Start-Stop (25 of 25), which is why the most common battery type is EFB, with 70 Ah. The usual case size is L3 (278 × 175 × 190 mm).
- Model fact: the Audi A3 8V mainly uses case sizes L3 (278 × 175 × 190 mm), L4 (315 × 175 × 190 mm) and L2 (242 × 175 × 190 mm). A battery of a different size will not sit securely in the car’s battery tray.
- General tip: if your car came from the factory with an AGM battery, replace it with another AGM; if it has an EFB, with an EFB or an AGM. A conventional battery in a Start-Stop car wears out much sooner and the system may stop working.
- General tip: on Seat, Volkswagen and Audi models with Start-Stop, the new battery is usually coded into the energy management system with a diagnostic tool, so that the alternator charges it according to its type and capacity.
- General tip: in a compact car that mixes town and open-road driving, the battery suffers most in winter and with lots of equipment switched on (heated rear window, heated seats). If cold starts become sluggish, have it checked before it leaves you stranded.

## Frequently asked questions

### Which battery does the Audi A3 (8V, 2012-2020) take?

With Start-Stop, the Audi A3 (8V, 2012-2020) usually takes a battery like the Varta N70: EFB, 70 Ah and 760 A, in case size L3. Versions without Start-Stop take the Varta E11 (conventional, 74 Ah and 680 A); the table shows the battery for each engine.

### Can I fit a standard battery in my Audi A3 with Start-Stop?

No. On versions that come with an EFB, such as the Varta N70, you can fit another EFB or upgrade to AGM, but not drop down to a conventional battery: it would last far less with the constant stopping and restarting of Start-Stop.

### What size battery does the Audi A3 take?

Depending on the engine, the Audi A3 8V uses these case sizes: L3 (278 × 175 × 190 mm), L4 (315 × 175 × 190 mm) and L2 (242 × 175 × 190 mm); dimensions are length × width × height. Also check that the positive terminal is on the same side as on your current battery.

### Does the Varta N70 fit the Audi A3 8V?

Yes, it is one of the recommended batteries for the Audi A3 8V with the 1.0 TFSI, 1.2 TFSI, 1.4 TFSI, 1.4 TFSI e-tron, 1.4 TSI and 1.5 TFSI engines (19 of the 25 engines in the table). For the others, check their row in the table or search by number plate.

### How do I find out exactly which battery my Audi A3 takes?

Enter your number plate or chassis number (VIN) in our battery finder: it identifies the exact engine and shows you only the compatible batteries. You can also check the label on your current battery: capacity (Ah), cold cranking (A, EN standard) and technology (AGM, EFB or conventional).
