# Battery finder by VIN (chassis number)

> The VIN (vehicle identification number) pins down your vehicle exactly: make, model, engine and equipment. From those 17 characters we know which battery it left the factory with (capacity, cold cranking amps, size, terminal layout and whether it has Start-Stop) and we only show you the ones that fit. It works for imported cars, foreign-registered vehicles, or when you simply do not have the number plate to hand.

## Where to find the VIN

- **Registration document**: In the V5C logbook (section E on EU registration documents). It is 17 characters long and never contains the letters I, O or Q.
- **Bottom of the windscreen**: On a plate visible from outside, in the lower corner of the windscreen on the driver's side.
- **Door pillar**: On the label inside the driver's door frame, next to the tyre pressure data. Also stamped in the engine bay.

## Why look up the battery by VIN?

The VIN follows the same international standard (ISO 3779) everywhere, so it works for vehicles from any country, including imports and foreign-registered cars. It avoids the compatibility mistakes you get when searching by make and model alone: two versions of the same car can take different batteries depending on the engine and equipment.

### What is the VIN or chassis number?
It is the unique 17-character code the manufacturer assigns to each vehicle (Vehicle Identification Number). It encodes the manufacturer, model, engine and serial number. It never contains the letters I, O or Q, to avoid confusion with digits.

### Does it work for an imported or foreign-registered car?
Yes. The VIN is universal: we identify make, model and engine regardless of where the car is registered. It is the best option when the number plate is not Spanish, Portuguese or Italian.

### Is it safe to enter my VIN?
Yes. The VIN does not identify the owner and we only use it to look up the vehicle's technical data and recommend a battery. We do not link it to personal data or share it.

### What if my vehicle is not found?
Check that you typed all 17 characters (zeros are not the letter O). If it still does not appear, use the search by number plate, by make, model and engine, or search by capacity (Ah) or by the dimensions of your current battery.

### Is the battery shown exactly the one I need?
We show the batteries that fit according to the vehicle specifications and the battery manufacturer's application catalogue: capacity, cold cranking amps, size, terminal position and technology (AGM, EFB or conventional). If you are torn between two, our technical team is happy to help.
