Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea. ### Why this marine battery? - **Marine design** built for boat swell and vibration - **Dual function** starts the engine and powers onboard services - **Sealed and safe** maintenance-free even when the boat rolls 🔌 Voltage 12 V ⚡ Capacity 150 Ah C20 🔋 Cold cranking 825 A EN-1 📏 Dimensions 484×171×241 mm ⚙️ Technology AGM 🧭 Polarity Positivo a la derecha ⚖️ Weight 46,7 kg 🏷️ Model Professional Deep Cycle AGM ## Description ## Varta LAD150 Professional Deep Cycle AGM 150Ah 825A 12V Battery 12*V* Voltage 150*Ah* Capacity 825*A* Cold cranking 46,7*kg* Weight The **Varta LAD150 battery** is the **12 V**, **150 Ah** model delivering **825 A** of cold cranking power (EN) from Varta's **Professional Deep Cycle AGM** range, designed for motorhomes, boats and auxiliary power equipment. Measuring 484 × 171 × 241 mm and with the positive terminal on the right, it is the direct replacement for vehicles that leave the factory with a 150 Ah battery in this format. - 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 LAD150 battery Designed for motorhomes, boats and auxiliary power equipment, the Varta LAD150 is a direct replacement when you need its same 150 Ah capacity and format. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 46,7 kg and has a type 1 terminal and a B00 hold-down. ### Size and fitting of the Varta LAD150 In terms of format, the Varta LAD150 measures 484 × 171 × 241 mm (length × width × height) and weighs 46,7 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 B00 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 LAD150 and the Professional Deep Cycle AGM range The **Professional Deep Cycle AGM** range consists of AGM deep-cycle batteries designed to run equipment for hours: fridge, lighting, electric outboard or on-board electronics in boats and motorhomes. They accept deep discharges and repeated recharging that would ruin a starter battery, and being AGM they need no maintenance and carry no risk of spillage. 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 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. 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 is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand makers cannot always assure. ### Manufacturer's warranty The Varta LAD150 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.

Yes. The LAD150 from Varta uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for boats with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### 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 LAD150; 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 change this battery step by step? 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 LAD150 battery have? 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. On confirmed defect after technical inspection, we replace the LAD150 model at no cost. ### What is the delivery time for this battery? 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 LAD150 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. ### 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 LAD150 battery last? Expected lifespan of the Varta LAD150 is 5 to 8 years in mild-climate boat use with 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 LAD150 model? Dimensions (length × width × height) are 484×171×241 mm — also written as 484x171x241 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 much does the Varta LAD150 battery weigh? It weighs 46,7 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). ### What is the capacity and CCA of the LAD150 model? Nominal capacity 150 Ah[?cca: and [cold-cranking amps 825 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 LAD150 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 LAD150 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the LAD150 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 LAD150 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 do users say about the Varta LAD150 battery?
