# Car Batteries > Find your compatible car battery by make, model, engine and year. AGM, EFB and SLI by Varta, Tudor, Exide, Optima and Kronobat. 24h delivery **Category:** [Start](https://baterias.com/gb/beginning) → [Batteries](https://baterias.com/gb/batteries) → [Starter Batteries](https://baterias.com/gb/starter-batteries) - **Canonical URL**: https://baterias.com/gb/car-batteries - **Language**: en-GB ## Description **Find the battery for your car** using the finder right below: select your vehicle step by step and see only 100% compatible batteries. Other quick paths: by number plate, by part-number from the manufacturer or by the **code printed** on your current battery (Varta E11, Tudor TC700, YTX12-BS, etc.). ## How to choose the right car battery A passenger car battery has two jobs: **cranking the engine** from cold and **powering the on-board electronics** when the car is stopped (alarm, GPS, dashcam, smart key). Going below the manufacturer's minimum causes lazy cold cranks, Start-Stop failures, premature discharge after a few unused days and, on modern cars, disabled features such as comfort closing or parking sensors. Three figures are mandatory and must NEVER be lower than the original: - **Capacity (Ah)** — total energy. A supermini runs on 40-55 Ah; an SUV with high loads needs 70-95 Ah. - **CCA EN cranking current** — peak at -18 °C on the first turn. Diesel and large engines need 700-1,000 A; small petrol 400-540 A. - **Technology** — SLI / EFB / AGM. With Start-Stop, NEVER drop to SLI; with factory AGM, never replace with EFB. ### How to choose by make, model and engine The European car fleet is huge: a **battery for BMW 3 Series 320d** is not the same as for an **Audi A4 2.0 TDI**, and a **VW Golf Start-Stop** mandates EFB. Select **make, model, engine and year** in the finder and you'll see only batteries compatible with your specific vehicle. Common queries: *Renault Clio 1.5 dCi battery*, *Peugeot 308 1.6 HDi battery*, *Seat León 1.4 TSI battery*, *Hyundai Tucson 1.7 CRDi battery*, *Toyota Corolla hybrid battery*. ### Indicative table by car segment Car segment Typical capacity Indicative CCA Technology Petrol supermini (Citroën C3, Fiat Panda, Renault Clio) 40-55 Ah 360-480 A SLI / EFB Compact Start-Stop (VW Golf, Seat León, Peugeot 308) 60-72 Ah 540-720 A EFB SUV / D-segment (BMW 3, Audi A4, Tiguan) 70-95 Ah 680-850 A AGM Large diesel / 4x4 (X5, Q7, Touareg, Discovery) 90-110 Ah 800-950 A AGM Hybrid (HEV/PHEV — 12 V battery) 45-70 Ah 360-540 A AGM ### Most-searched OEM codes If you know the OEM code already on your car, search by code directly: **Varta E11** (Silver Dynamic 74Ah), **Varta F21** (Silver Dynamic AGM 80Ah), **Varta E39** (Blue Dynamic EFB 70Ah), **Tudor TC700**, **Tudor TK700**, **Exide EK700**. Typical OEM specs: 60Ah 540A for small petrol, 70Ah 680A EFB for compact Start-Stop, 80-95Ah 800-850A AGM for premium SUV and saloon. ### Leading brands for cars - [Varta](/gb/batteries-varta) — factory-fitted by most European OEMs. The Blue Dynamic, [Blue Dynamic EFB](/gb/batteries-varta-blue-dynamic-efb) and [Silver Dynamic AGM](/gb/batteries-varta-silver-dynamic-agm) lines cover 95% of the European fleet. - [Tudor](/gb/batteries-tudor) — European manufacturing (Exide group).

Select make, model, engine and year in the finder — only 100% compatible batteries are shown. ### **How long does a car battery last?** 4-6 years in normal use without Start-Stop. 5-7 years with a properly sized AGM. Drops to 2-3 years if undersized or if the car sits idle for many days in winter. ### **How do I know which battery to buy?** Three routes: 1) make/model/engine/year in the finder, 2) lift the bonnet and read the code on the current battery (Varta E11, Tudor TC700…), 3) note Ah and CCA from the label and search by specifications. ### **Is AGM better than EFB?** If the car came with AGM from factory (regenerative-braking Start-Stop, premium audio, premium vehicles), AGM is mandatory. If EFB is OEM (basic Start-Stop), EFB suffices but AGM is always a valid upgrade. Never drop from AGM to EFB. ### **Can I fit the battery myself?** Mechanically yes for most pre-2015 cars. Modern cars with BMS (Battery Management System) require *battery registration / coding* via OBD — without it, the system keeps charging with the old profile and the new battery ages prematurely. ### **How long does shipping take?** Standard delivery **1 to 5 working days** to your country.
