Sealed and maintenance-free. ### 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 85 Ah C20 πŸ”‹ Cold cranking 465 A EN-1 πŸ“ Dimensions 260Γ—169Γ—230 mm βš™οΈ Technology AGM 🧭 Polarity Positive on the right βš–οΈ Weight 25,3 kg 🏷️ Model Professional Deep Cycle AGM ## Description ## Varta LAD85 Professional Deep Cycle AGM 85Ah 465A 12V Battery 12*V* Voltage 85*Ah* Capacity 465*A* Cold cranking 25,3*kg* Weight The **Varta LAD85 battery** is the **12 V**, **85 Ah** model delivering **465 A** of cold cranking power (EN) from Varta's **Professional Deep Cycle AGM** range, designed for motorhomes, boats and auxiliary power equipment. It replaces the original battery in vehicles with the 260 Γ— 169 Γ— 230 mm format without any modifications: the same 85 Ah capacity and the same terminal layout (positive on the right). - Ideal for motorhomes, marine use and domestic power on board. - Dual cycle: it both cranks the engine and powers auxiliary equipment. - More endurance on board than a conventional starter battery. - Tolerates deep discharges and repeated recharging without degrading. ### Applications of the Varta LAD85 battery Designed for motorhomes, boats and auxiliary power equipment, the Varta LAD85 is a direct replacement when you need its same 85 Ah capacity and format. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 25,3 kg and has a type 1 terminal and a B00 hold-down. ### Size and fitting of the Varta LAD85 Its external dimensions are 260 Γ— 169 Γ— 230 mm and it weighs 25,3 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 B00 hold-down and a type 1 terminal, 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 LAD85 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. 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 Choosing Varta means going with the reference the car manufacturer itself signed off on in its day. Against own-brand batteries, the difference is not the purchase price but how many winters the battery lasts before leaving you stranded. 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 LAD85 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.

Yes. The LAD85 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 is the Varta LAD85 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 (βˆ’) 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 β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What is the service life of the LAD85 model? Expected lifespan of the Varta LAD85 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 size is this battery? Dimensions (length Γ— width Γ— height) are 260Γ—169Γ—231 mm β€” also written as 260x169x231 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. ### Is the LAD85 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 β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The LAD85 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Varta LAD85? 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 β€” 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. ## Reviews - **Average rating**: 4.76 / 5 (61 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-03*
