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 74 Ah C20 🔋 Cold cranking 680 A EN-1 📏 Dimensions 278×175×190 mm ⚙️ Technology Plomo-Ácido 🧭 Polarity Positivo a la derecha ⚖️ Weight 16,82 kg 🏷️ Model Professional Starter ## Description ## Varta LFS74 Professional Starter 74Ah 680A 12V Battery 12*V* Voltage 74*Ah* Capacity 680*A* Cold cranking 17,3*kg* Weight The **Varta LFS74 battery** is the **12 V**, **74 Ah** model delivering **680 A** of cold cranking power (EN) from Varta's **Professional Starter** range, designed for starting marine engines and recreational vehicles in demanding conditions. Its 278 × 175 × 190 mm dimensions and positive terminal on the right make it the exact replacement for the 74 Ah battery fitted as standard in many vehicles. - Reliable starting of marine engines and recreational vehicles, in the cold too. - Direct replacement for the original starter battery in marine 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 LFS74 battery With 74 Ah, the Varta LFS74 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 17,3 kg and has a type 1 terminal and a B13 hold-down. ### Size and fitting of the Varta LFS74 The Varta LFS74 is made in the 278 × 175 × 190 mm format and weighs 17,3 kg. The positive terminal on the right determines which side the cables run to: it is the detail that causes the most buying mistakes, so it is worth checking before ordering. It uses a B13 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. Before replacing it, measure the space your current battery occupies: if it matches on all three dimensions and on terminal position, the swap is direct and needs no adapters. ### The Varta LFS74 and the Professional Starter range The **Professional Starter** range consists of pure starter batteries for leisure and marine use, built to give marine engines and recreational vehicles a powerful, dependable start. Unlike deep-cycle or dual-purpose units, they are optimised for cranking rather than for powering equipment over long periods: the choice when all you need is to fire up the engine with confidence. Its construction puts current peak and resistance to the marine environment (vibration, damp and salt) first, 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 Varta is an original equipment (OEM) supplier to a good share of Europe's car manufacturers: many cars leave the factory with a Varta fitted. Buying a replacement means, in most cases, refitting the original battery with the same quality and the brand's official warranty. 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's production combines automated lines with verification of more than 100 parameters per unit; that traceability is what underpins its reputation for reliable starting throughout the battery's life. ### Manufacturer's warranty The Varta LFS74 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 seasons when it sees less use. 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-lfs74-74ah-680a-12v-en.pdf) ## Frequently asked questions ### How do I verify this battery is the right one? 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 LFS74; 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 LFS74 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 is the warranty period of this battery? This battery includes 1 year of official manufacturer warranty against manufacturing defects. Coverage includes cell breakdowns, internal short-circuits and abnormal capacity decreases. Wear from misuse (prolonged overcharging, wrong charger or faulty alternator) is not covered. If the battery fails, we replace it at no cost after a technical inspection. ### When will I receive the LFS74 model? 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. ### Can I return the Varta LFS74 battery if it doesn't fit or doesn't work? 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 LFS74 battery cost? The current price at baterias.com is 125,62 € (VAT included; 103,82 € 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 the Varta LFS74 battery? 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. ### What is the service life of the LFS74 model? Expected lifespan of the Varta LFS74 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 measurements of the LFS74 model? Dimensions (length × width × height) are 278×175×190 mm — also written as 278x175x190 mm and correspond to the European L3 case size — 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 much does the Varta LFS74 battery weigh? It weighs 16,8 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 LFS74 battery have? Nominal capacity 74 Ah[?cca: and [cold-cranking amps 680 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. ### Is the LFS74 valid for my vehicle? 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 LFS74 fits 4 verified vehicle versions in our database. ### Which batteries are equivalent to the Varta LFS74? 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. ### Is the LFS74 model better than its equivalents from other brands? 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 LFS74 model have?
