# Battery types: starter, deep cycle, traction and stationary > Buy starter, deep cycle, traction and stationary batteries online: over 2,760 products from Exide, Varta, Trojan and 20 more brands, with VAT included. **Category:** [Beginning](https://bateriasonline.es/en/) - **Canonical URL**: https://bateriasonline.es/en/batteries - **Language**: en ## Description Choose your battery type by application and buy online with the final price including VAT and the shipping cost shown before you pay. Every battery here is described by the figures that actually decide a purchase: voltage, capacity in Ah, cold cranking current, case size, terminal layout and chemistry. Start with the job the battery has to do, then filter by those numbers. Starting a vehicle, powering a caravan, moving a forklift or backing up a server all need a different design, even when the voltage matches. ## Four families, four ways of using energy Batteries differ less in their label than in how they are discharged. Choosing the right family first avoids most premature failures. - **Starter batteries** deliver a very high current for a few seconds to crank an engine, then get recharged by the alternator. See our [starter batteries for cars, motorcycles, trucks and boats](https://bateriasonline.es/en/starter-batteries). - **Deep cycle batteries** release energy slowly over hours and tolerate repeated deep discharges: caravans, solar systems, wheelchairs. Browse [deep cycle batteries](https://bateriasonline.es/en/deep-cycle-batteries). - **Traction batteries** move electric machines every working day, including 2 V PzS/PzB cells for forklifts. Find them in [traction batteries](https://bateriasonline.es/en/traction-batteries). - **Standby batteries** stay on float charge and only work when the mains fails: UPS, telecom, alarms. Go to [stationary batteries](https://bateriasonline.es/en/stationary-batteries). ## The data sheet, line by line **Voltage (V)** must match the system: 12 V is the common case, while 2 V, 6 V and 8 V units are combined in series for higher voltages. **Capacity (Ah)** tells you how much energy is stored; for cycling use it is usually quoted at a 20-hour rate. **CCA or EN** measures cranking power at −18 °C and matters only for starting. **Dimensions and terminal position** decide whether the battery physically fits and whether the cables reach. ## Lead-acid, AGM, EFB, GEL or lithium Flooded lead-acid is the simplest and most widespread design. EFB strengthens it for frequent restarts. AGM holds the electrolyte in glass mats, is sealed and accepts more cycling. GEL is the most tolerant of slow, deep discharges. Lithium (LiFePO4 or Li-ion) is far lighter and keeps its voltage stable, but needs a compatible charging profile; check our [battery chargers](https://bateriasonline.es/en/battery-chargers) before switching chemistry. ## Frequently asked questions ### Can I use a starter battery for a caravan or solar system? It will work for a short time, but its thin plates are not built for deep discharges and it loses capacity quickly. A deep cycle model is the sensible choice for that use. ### Is a higher Ah figure always better? Only if the battery still fits and your charging source can refill it. An oversized battery that is never fully charged ages faster than a correctly sized one. ### Where do I find the data of my current battery? On the label: voltage, Ah, CCA or EN and often a reference code. Measure the case and note which side the positive terminal is on before comparing. ## Choose by brand The same battery types: starter, deep cycle, traction and stationary, 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) - [Fulbat batteries](https://bateriasonline.es/en/fulbat-batteries) (317) - [Long batteries](https://bateriasonline.es/en/long-batteries) (281) - [Varta batteries](https://bateriasonline.es/en/varta-batteries) (273) - [Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries) (258) - [Fullriver batteries](https://bateriasonline.es/en/fullriver-batteries) (177) - [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) - [Trojan batteries](https://bateriasonline.es/en/trojan-batteries) (119) - [MK batteries](https://bateriasonline.es/en/mk-batteries) (114) - [Ritar batteries](https://bateriasonline.es/en/ritar-batteries) (109) - [Q-Battery Batteries](https://bateriasonline.es/en/q-battery-batteries) (99) - [Motobatt batteries](https://bateriasonline.es/en/motobatt-batteries) (58) - [Odyssey batteries](https://bateriasonline.es/en/odyssey-batteries) (52) - [Leoch batteries](https://bateriasonline.es/en/leoch-batteries) (49) - [Deka batteries](https://bateriasonline.es/en/deka-batteries) (34) - [Sonnenschein Batteries](https://bateriasonline.es/en/sonnenschein-batteries) (28) - [Optima batteries](https://bateriasonline.es/en/optima-batteries) (23) - [Cyclon batteries](https://bateriasonline.es/en/cyclon-batteries) (11) ## 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*
