Sealed and maintenance-free. For onboard loads (fridge, sounder, lights) you also need a service battery. ### Why this marine starting battery? - **Marine design** built for boat swell and vibration - **Starting in demanding conditions** maximum cranking power - **Sealed and safe** maintenance-free even when the boat rolls 🔌 Voltage 12 V ⚡ Capacity 120 Ah C20 🔋 Cold cranking 780 A EN-1 📏 Dimensions 349×175×236 mm ⚙️ Technology Plomo-Ácido 🧭 Polarity Positivo a la izquierda ⚖️ Weight 29,01 kg 🏷️ Model Professional Starter ## Description ## Varta LFS120 Professional Starter 120Ah 780A 12V Battery 12*V* Voltage 120*Ah* Capacity 780*A* Cold cranking 30.91*kg* Weight The **Varta LFS120 battery** is the **12 V**, **120 Ah** model delivering **780 A** of cold cranking power (EN), from Varta's **Professional Starter** range, designed for starting marine engines and recreational vehicles in demanding conditions. It replaces the original battery in vehicles with the 349 × 175 × 236 mm format without any modifications: the same 120 Ah capacity and the same terminal layout (positive on the left). - Reliable starting of marine engines and recreational vehicles, in the cold too. - Direct replacement for the original starter battery in boating and leisure use. - Optimised for starting in demanding conditions: maximum power at the moment of cranking. - Rugged construction, resistant to vibration and to the marine environment. ### Applications of the Varta LFS120 battery With 120 Ah, the Varta LFS120 is sized for starting marine engines and recreational vehicles in demanding conditions, as a direct replacement for the original battery. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 30.91 kg and has a B00 hold-down. ### Format and fitting of the Varta LFS120 In terms of format, the Varta LFS120 measures 349 × 175 × 236 mm (length × width × height) and weighs 30.91 kg. The positive terminal on the left determines which side the cables sit on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. It uses a B00 hold-down, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal positions before buying avoids the most common mistake when replacing a battery. ### The Varta LFS120 and the Professional Starter range The **Professional Starter** range consists of pure starter batteries for leisure and boating, built to give marine engines and recreational vehicles powerful, reliable starting. Unlike cycling or dual-purpose batteries, they are optimised for starting rather than for powering equipment over long periods: the choice when all you need is to fire up the engine with confidence. Their construction prioritises peak current and resistance to the marine environment (vibration, damp and salt) rather than the ability to run equipment for hours: that is what the deep-cycle and dual-purpose ranges are for. ### Why choose a Varta battery When a workshop recommends Varta, it is not down to marketing: it is one of the brands with the lowest return rates in the sector, with application coverage spanning practically the entire European fleet, from the city car to the commercial vehicle. Varta batteries are made under the Clarios group with German technology and quality controls that make them one of the best-selling choices in Europe. As a lead battery, it is 100% recyclable through any collection point. Varta is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand labels cannot always promise. ### Manufacturer's warranty The Varta LFS120 battery comes with **a 1-year official warranty** from the manufacturer. ### Care and maintenance In leisure applications, avoiding discharges below 50% of capacity multiplies the number of cycles the battery will deliver. A suitable charger and, where possible, a solar regulator keep it healthy through the quieter seasons. To extend its life, recharge it as soon as possible after each discharge and never leave it flat over the winter. A trickle charger is the best investment for getting many cycles out of it. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data. [Download technical sheet (PDF)](/fichastecnicas/data-sheet-battery-varta-lfs120-120ah-780a-12v-en.pdf) ## Frequently asked questions ### How do I check that the Varta LFS120 battery fits my vehicle? Three ways: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team for the LFS120; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET). ### How do I fit the LFS120 model in my boat? In most boats it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What warranty does the Varta LFS120 battery have? The official manufacturer warranty is 1 year and covers manufacturing defects. Coverage includes cell breakdowns, internal short-circuits and abnormal capacity decreases. Damage from misuse is excluded: prolonged overcharging, unsuitable chargers or a faulty alternator. If the battery fails, we replace it at no cost after a technical inspection. ### How long does Varta LFS120 delivery take? In mainland Spain and Portugal it arrives in 24 h if you order before 17:00 and the battery is in stock — it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships. ### Are returns accepted on this battery? Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE — we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period. ### How much does the Varta LFS120 battery cost? The current price at baterias.com is 289,80 € (VAT included; 239,50 € excl. VAT), updated every 24 hours. The applicable VAT may vary with the destination country and is confirmed in the cart. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). ### Where can I buy this battery with full warranty? At baterias.com — authorised distributor with real stock, 24h delivery in mainland Spain and Portugal if you order before 17:00, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point. ### How long does the Varta LFS120 battery last? Expected lifespan of the Varta LFS120 is 4 to 6 years in regular boat use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the dimensions of the Varta LFS120 battery? Dimensions (length × width × height) are 349×175×236 mm — also written as 349x175x236 mm — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### How many kilos does this battery weigh? It weighs 29 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre). ### How many amps does the Varta LFS120 battery have? Nominal capacity 120 Ah[?cca: and [cold-cranking amps 780 A]] at 12 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer. ### Will the Varta LFS120 battery fit my boat? Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET). The LFS120 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the LFS120 model? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop boats. See the "Equivalents" section to view recommended options at the same performance level. ### Which is better: Varta LFS120 or an alternative from another brand? This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section. ### What reviews does the LFS120 model have?
