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 Ford Focus Mk2

The second-generation Focus, in five-door, three-door, estate, saloon and Coupé-Cabriolet form, uses LB-series cases, which are lower than the L cases of German cars: that is the first thing to respect when you replace the battery. The TDCi diesels and the 2.5 ST take 72 Ah in an LB3 case, the 1.4 to 2.0 petrol engines, including the Flexifuel and gas versions, 60 Ah in an LB2, and the RS, 80 Ah in an LB4. Only some 1.6 TDCi models with Start-Stop have a 65 Ah EFB.
- Model fact: the Ford Focus Mk2 mainly uses case sizes LB3 (278 × 175 × 175 mm), LB2 (242 × 175 × 175 mm) and LB4 (315 × 175 × 175 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 many Start-Stop cars the ECU manages battery charging, so when you replace the battery it is best to register the new one with a diagnostic tool.
- 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 Ford Focus Mk2 (2004-2012) take?

The Ford Focus Mk2 (2004-2012) usually takes a battery like the Varta E43: conventional, 72 Ah and 680 A, in case size LB3. Only the Start-Stop versions of the 1.6 TDCi take the Varta D54 (EFB, 65 Ah).

### Can I fit a standard battery in my Ford Focus Mk2 with Start-Stop?

No. On versions that come with an EFB, such as the Varta D54, 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 Ford Focus Mk2 take?

Depending on the engine, the Ford Focus Mk2 uses these case sizes: LB3 (278 × 175 × 175 mm), LB2 (242 × 175 × 175 mm) and LB4 (315 × 175 × 175 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 E43 fit the Ford Focus Mk2?

Yes, it is one of the recommended batteries for the Ford Focus Mk2 with the 1.6 TDCi, 1.8, 1.8 TDCi, 2.0 TDCi and 2.5 ST engines (5 of the 16 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 Ford Focus Mk2 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).
