It is not a starting battery: it replaces the lead-acid service bank at around 60 % less weight. ### 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 Positive on the right ⚖️ Weight 20 kg 🏷️ Model Professional Li-Ion Deep Cycle ## Description ## Varta LL150LT Professional Li-Ion Deep Cycle 150Ah 12.8V Battery 12.8*V* Voltage 150*Ah* Capacity The **Varta LL150LT 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). - Dual cycle: it both cranks the engine and powers auxiliary equipment. - Ideal for motorhomes, marine use and domestic power on board. - Tolerates deep discharges and repeated recharging without degrading. - More endurance on board than a conventional starter battery. ### Applications of the Varta LL150LT battery With 150 Ah, the Varta LL150LT is sized for motorhomes, boats and auxiliary power equipment, as a direct replacement for the original battery. 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 LL150LT Its outer dimensions are 353 × 175 × 190 mm. 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 LL150LT 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). Unlike a pure starter battery, this range tolerates deep discharges and repeated recharging without degrading: exactly what a motorhome or a boat that draws power with the engine off needs. It therefore combines cranking and domestic duty in a single dual-cycle battery. ### Why choose a Varta battery A good share of the vehicles on Europe's roads left the factory with a Varta fitted: the brand has been supplying the assembly lines of the major car groups for decades. Replacing with Varta means, in practice, giving the vehicle back the battery its manufacturer intended. Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year. 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 LL150LT battery comes with the **official manufacturer warranty**. ### 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.

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. ### How long does the Varta LL150LT battery last? Expected lifespan of the Varta LL150LT 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 are the dimensions of the Varta LL150LT 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. ### Will the Varta LL150LT 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 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The LL150LT typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which interchangeable batteries are there for this one? 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. ## 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 · 2026-09-30*
