Its built-in BMS protects it against overcharge, over-discharge and short circuit. ### Why this lithium marine battery? - **Deep-cycle service bank** daily discharges to 80 % with no capacity loss - **60 % less weight on board** the same energy as lead-acid in far less space - **Built-in BMS, maintenance free** protects against overcharge, over-discharge and short circuit 🔌 Voltage 12 V ⚡ Capacity 150 Ah C20 📏 Dimensions 353×175×190 mm ⚙️ Technology Litio (LiFePO4) 🧭 Polarity Positivo a la derecha ⚖️ Weight 20 kg 🏷️ Model Professional Li-Ion Deep Cycle ## Description ## Varta LL150 Professional Li-Ion Deep Cycle 150Ah 12.8V Battery 12.8*V* Voltage 150*Ah* Capacity The **Varta LL150 battery** is the **12.8 V**, **150 Ah** from the **Professional Li-Ion Deep Cycle** range, designed for motorhomes, boats and auxiliary power equipment. It replaces the original battery in vehicles with the 353 × 175 × 190 mm format without any modifications: the same 150 Ah capacity and the same terminal layout (positive on the right). - Tolerates deep discharges and repeated recharging without degrading. - More endurance on board than a conventional starter battery. - Dual cycle: it both cranks the engine and powers auxiliary equipment. - Ideal for motorhomes, marine use and domestic power on board. ### Applications of the Varta LL150 battery The Varta LL150 covers the needs of motorhomes, boats and auxiliary power equipment with 150 Ah of capacity and a construction built for that use. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a B13 hold-down. ### Size and fitting of the Varta LL150 In format, the Varta LL150 measures 353 × 175 × 190 mm (length × width × height). 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, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space your current battery occupies must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will have to change. ### The Varta LL150 and the Professional Li-Ion Deep Cycle range The **Professional Li-Ion Deep Cycle** is Varta’s new lithium (LiFePO4) series for leisure and marine use: far lighter than lead, it withstands thousands of cycles and uses nearly all of its capacity in each discharge. It is the premium choice for motorhomes and boats seeking maximum range and service life at minimum weight, with an integrated battery management system (BMS). The chemistry is built for draining and recharging the battery many times over — the typical pattern in leisure and marine use — where an ordinary car battery would sulphate within weeks. It offers endurance for the on-board equipment and the cranking power to turn the engine over when the moment comes. ### 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 an application coverage spanning practically the whole European vehicle parc, from the city car to the industrial vehicle. Varta combines more than a century of experience with Clarios's industrial production: it is the battery many manufacturers choose as standard and one of the most recommended by workshops. Like any lead-acid battery, it is 100% recyclable. More than 100 manufacturing parameters are checked on every Varta battery before it leaves the plant, a level of rigour that explains why so many workshops and manufacturers trust the brand as their first-choice replacement. ### Manufacturer's warranty The Varta LL150 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/ficha-tecnica-bateria-varta-ll150-150ah-12v-en.pdf) ## Frequently asked questions ### How do I check that the Varta LL150 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 LL150; 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 is the Varta LL150 battery installed in the vehicle? 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. It applies to defects such as damaged cells, internal short-circuits or abnormal capacity loss. 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 LL150 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. ### How do I return the LL150 model if it doesn't fit? 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. ### Where can I buy the Varta LL150 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. ### How many years does this battery last? Expected lifespan of the Varta LL150 is 4 to 7 years in regular use (depends on technology and climate). 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 size is this battery? Dimensions (length × width × height) are 353×175×190 mm — also written as 353x175x190 mm and correspond to the European L5 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 LL150 battery weigh? It weighs 20 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). ### Will the Varta LL150 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 LL150 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the LL150 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. ### Is the LL150 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 LL150 model have? The product rating, when available, is shown on the product page next to the stars. You can also check our public Trustpilot profile at shop level (4.5/5 from 11,582+ verified reviews). Most-praised points: reliable cold start, lifespan above 5 years and fast delivery; most common complaints mention BMS-equipped boats that need OBD registration after fitting. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-14*
