## Frequently asked questions

### How much does a 33Ah battery cost?
Between 135.85 € and 282.43 €, VAT included, depending on technology (AGM, Quadflex) and brand. Price grows with cold cranking amps (CCA) and Start-Stop technologies such as EFB or AGM.

### Can I fit a battery with more capacity than 33Ah?
Yes, as long as the dimensions and terminal layout match your tray and the CCA is equal or higher than the original. What you should never do is fit LESS capacity than the manufacturer specifies.

### What sizes do 33Ah batteries usually have?
The most common sizes for this rating are 195x130x168 · 200x130x163 · 196x130x180 (length × width × height, in mm). Always check your tray before buying: each product page lists exact dimensions.

### AGM, EFB or conventional for my car?
It depends on the equipment: with advanced Start-Stop (regenerative braking) fit AGM; with basic Start-Stop, EFB — or AGM, never less —; without Start-Stop a quality conventional battery is enough. On this page you can filter by technology to see only the ones that suit your case.

### How do I know which polarity I need?
Look at your current battery from the front with the terminals on the far side: if the positive (+) sits on the right it is right polarity; on the left, left polarity. Every card shows the polarity and you can filter by it above — with the wrong polarity the cables will not reach the terminal.
