# 11Ah batteries

We stock 15 batteries of 11 Ah (lead-acid, AGM, Quadflex) priced between 32.94 € and 169.00 €, VAT included. Amp-hour capacity is the total energy the battery stores: when replacing, always fit equal or slightly higher capacity than the original, never lower.

A 11Ah battery belongs to the small segment: motorcycles, scooters, quads, jet skis, UPS and electronics. Compact format and vibration resistance rule here; always check terminal layout before buying.

At this rating we stock lead-acid, AGM, Quadflex. Start-Stop golden rule: never downgrade technology — factory AGM must be replaced with AGM; factory EFB can be upgraded to AGM but never downgraded to conventional.

Brands available right now in at 11 Ah: Exide (6), Varta (5), Motobatt (3), Tudor (1). All with official warranty and live stock.

Cold cranking amps (CCA, EN standard) of the listed models range from 80 to 230 A. When replacing, pick a CCA equal or higher than your original: every amp counts in winter.

## Frequently asked questions

### How much does a 11Ah battery cost?
Between 32.94 € and 169.00 €, VAT included, depending on technology (lead-acid, 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 11Ah?
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 11Ah batteries usually have?
The most common sizes for this rating are 150x90x130 · 136x91x146 · 150x90x110 (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.
