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 πŸ”Œ Voltage 12 V ⚑ Capacity 150 Ah C20 πŸ”‹ Cold cranking 825 A EN-1 πŸ“ Dimensions 484Γ—171Γ—241 mm βš™οΈ Technology AGM 🧭 Polarity Positive on the right βš–οΈ 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 Γ— 171 Γ— 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 Γ— 171 Γ— 241 mm (length Γ— width Γ— 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 β€” the typical pattern in leisure and marine use β€” 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 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.

What does this technology offer? 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. ### Is this a starting or a service (leisure) battery? Service: it is designed to power electronics, lights, the fridge or the windlass for hours, withstanding deep discharges. On boats with two circuits the ideal is one starting battery and one service battery. ### In what position can it be installed on the boat? Being AGM, it is sealed and does not spill: it can be mounted tilted (never upside down) and copes well with vibration and wave impacts. Secure it firmly and keep the terminals away from water. ### What are the measurements of the LAD150 model? Dimensions (length Γ— width Γ— height) are 484Γ—171Γ—241 mm β€” also written as 484x171x241 mm β€” 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. ### On which side is the positive of the LAD150 model? Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-31*
