# 85Ah batteries

We stock 16 batteries of 85 Ah (lead-acid, AGM, GEL) priced between 69.18 € and 357.03 €, 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.

At 85Ah we enter SUV, larger diesel and premium saloon territory (BMW 3/5 Series, Audi A4/A6, Tiguan, X5…). AGM is factory-standard in this segment: if your car has it, always replace like for like.

At this rating we stock lead-acid, AGM, GEL. 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 85 Ah: Exide (5), Varta (3), Tudor (2), Ritar (2), Fullriver (2), Trojan (1). All with official warranty and live stock.

Cold cranking amps (CCA, EN standard) of the listed models range from 350 to 850 A. When replacing, pick a CCA equal or higher than your original: every amp counts in winter.

## Frequently asked questions

### How much does a 85Ah battery cost?
Between 69.18 € and 357.03 €, VAT included, depending on technology (lead-acid, AGM, GEL) 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 85Ah?
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 85Ah batteries usually have?
The most common sizes for this rating are 315x175x175 · 353x175x175 · 315x175x190 (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.
