## How we choose the battery for each engine

We start from the battery application data by engine (KType TecDoc) that our number plate search also uses, so the guide and the search always recommend the same thing. If an engine accepts more than one battery, it is because the battery changes with the version: with or without Start-Stop, or depending on the equipment. We never suggest a lower technology than the original: if the car has AGM, AGM; if it has EFB, EFB or AGM.

## Frequently asked questions

### How do I know which battery my car takes?

The most reliable way is to search by number plate or chassis number (VIN), which identifies the exact engine. If you do not have it to hand, choose your model in this guide and find your engine in the table.

### What is the difference between an AGM, an EFB and a conventional battery?

A conventional (lead-acid) battery is for cars without Start-Stop. An EFB withstands more charge and discharge cycles and is fitted to many basic Start-Stop cars. AGM is the most cycle-resistant and is used in Start-Stop cars with regenerative braking and in cars with high electrical demand.

### Can I fit a battery with more amps than the one in my car?

Yes, as long as it has the same case size, the positive terminal on the same side and the same or better technology. A few extra amp hours will not harm the car; lower cold cranking current (A), on the other hand, can cause problems in cold weather.
