Final price with VAT included. **Category:** [Beginning](https://bateriasonline.es/en/) → [Battery types: starter, deep cycle, traction and stationary](https://bateriasonline.es/en/batteries) - **Canonical URL**: https://bateriasonline.es/en/starter-batteries - **Language**: en ## Description Lead-acid, AGM, EFB, GEL and lithium starter batteries: find yours by VIN, vehicle model or reference and buy online with VAT included. A starter battery has one main task: push hundreds of amps into the starter motor for a few seconds, in any weather, and then recover quickly. Here you will find them for cars, start-stop vehicles, motorcycles, commercial vehicles, boats and garden machinery. Pick the vehicle type first, then compare cold cranking amps, capacity and case format. ## Which subcategory fits your vehicle - [Car batteries](https://bateriasonline.es/en/car-batteries) for petrol and diesel passenger cars without automatic engine stop. - [Start-stop batteries](https://bateriasonline.es/en/start-stop-batteries-agm-efb) in EFB and AGM for cars that switch the engine off at traffic lights. - [Motorcycle batteries](https://bateriasonline.es/en/motorcycle-batteries), from small scooters to large touring bikes, including lithium. - [Truck and heavy vehicle batteries](https://bateriasonline.es/en/truck-agricultural-batteries), usually in 12 V pairs wired for 24 V. - [Marine batteries](https://bateriasonline.es/en/marine-boat-batteries) for engine starting and dual-purpose use on board. Classic cars, lawn tractors and auxiliary back-up batteries also have their own sections inside this family. ## The three numbers that matter most **CCA / EN** is the current the battery supplies at −18 °C while staying above a minimum voltage. Diesel engines and cold climates need more of it. **Ah** indicates reserve energy for the electronics when the engine is off. **Case size and polarity** are non-negotiable: a battery with the positive on the wrong side may not connect at all. As a rule, match or slightly exceed the original CCA and keep the same Ah range. Going much higher in Ah rarely helps if the alternator cannot recharge it during short trips. ## Technology choice for starting Conventional flooded batteries remain right for most older cars and trucks. EFB and AGM are required when the vehicle came with them, because the charging system is programmed for that chemistry. Lithium starter batteries save weight, mainly in motorcycles, and need a charger with a lithium mode. ## Frequently asked questions ### Why does my battery start well in summer and fail in winter? Cold slows the chemical reaction and thickens engine oil at the same time, so the engine needs more current exactly when the battery can give less. A battery already near the end of its life shows it first on a frosty morning. ### Can a starter battery be fully discharged? It should be avoided. Starter plates are thin and deep discharges cause sulphation, which permanently reduces capacity. Recharge it as soon as possible if it goes flat. ## Choose by brand The same starter batteries, filtered by manufacturer. Each brand has its own page with all its references and a buying guide. - [Exide batteries](https://bateriasonline.es/en/exide-batteries) (338) - [Varta batteries](https://bateriasonline.es/en/varta-batteries) (273) - [Fulbat batteries](https://bateriasonline.es/en/fulbat-batteries) (185) - [Tudor batteries](https://bateriasonline.es/en/tudor-batteries) (146) - [Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries) (133) - [Deta batteries](https://bateriasonline.es/en/deta-batteries) (128) - [Fullriver batteries](https://bateriasonline.es/en/fullriver-batteries) (105) - [Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries) (77) - [Motobatt batteries](https://bateriasonline.es/en/motobatt-batteries) (58) - [Odyssey batteries](https://bateriasonline.es/en/odyssey-batteries) (52) - [Long batteries](https://bateriasonline.es/en/long-batteries) (51) - [Optima batteries](https://bateriasonline.es/en/optima-batteries) (18) - [Trojan batteries](https://bateriasonline.es/en/trojan-batteries) (3) ## Products in this category | Product | Brand | Price | |---|---|---| | [Exide EL600 · Start-Stop battery 12V 60Ah 640A](https://bateriasonline.es/en/exide-el600) | Exide | 74,99 € | | [Varta A7 (formerly E39) · Start-Stop battery 12V 70Ah 760A](https://bateriasonline.es/en/varta-a7) | Varta | 122,95 € | | [Varta A6 (formerly F21) · Start-Stop battery 12V 80Ah 800A](https://bateriasonline.es/en/varta-a6) | Varta | 146,62 € | | [Varta M12 · Truck battery 12V 180Ah 1,400A](https://bateriasonline.es/en/varta-m12) | Varta | 175,04 € | | [Varta M18 · Truck battery 12V 180Ah 1,000A](https://bateriasonline.es/en/varta-m18) | Varta | 177,78 € | | [Tudor TK720 · Start-Stop battery 12V 72Ah 760A](https://bateriasonline.es/en/tudor-tk720) | Tudor | 106,10 € | | [Tudor TB740 · Car battery 12V 74Ah 680A](https://bateriasonline.es/en/tudor-tb740) | Tudor | 60,43 € | | [Exide EL800 · Start-Stop battery 12V 80Ah 800A](https://bateriasonline.es/en/exide-el800) | Exide | 87,78 € | | [Exide ETX14-BS · Motorcycle battery 12V 12Ah 200A](https://bateriasonline.es/en/exide-etx14-bs) | Exide | 32,74 € | | [Varta C14 · Car battery 12V 56Ah 480A](https://bateriasonline.es/en/varta-c14) | Varta | 54,99 € | | [Varta E44 · Car battery 12V 77Ah 780A](https://bateriasonline.es/en/varta-e44) | Varta | 83,41 € | | [Varta E46 · Start-Stop battery 12V 75Ah 730A](https://bateriasonline.es/en/varta-e46) | Varta | 116,98 € | | [Varta F18 · Car battery 12V 85Ah 800A](https://bateriasonline.es/en/varta-f18) | Varta | 95,57 € | | [Varta A8 (formerly D52) · Start-Stop battery 12V 60Ah 680A](https://bateriasonline.es/en/varta-a8) | Varta | 104,97 € | | [Varta H3 · Car battery 12V 100Ah 830A](https://bateriasonline.es/en/varta-h3) | Varta | 107,38 € | --- *bateriasonline.es — Batteries and accessories · 2026-11-10*
