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 72 Ah C20 πŸ”‹ Cold cranking 640 A EN-1 πŸ“ Dimensions 278Γ—175Γ—190 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 16 kg 🏷️ Model EXIDE Vintage ## Description ## Marine battery Exide EU72L Vintage 72Ah 640A 12V 12*V* Voltage 72*Ah* Capacity 640*A* Cold cranking 16*kg* Weight The **Exide EU72L marine battery** offers **12 V**, **72 Ah** and **640 A** of cold cranking current (EN) from the **Vintage** range with conventional lead-acid technology, designed for motor and sailing boats, both for engine starting and onboard services. Measuring 278 Γ— 175 Γ— 190 mm and the positive terminal on the left, it is the direct replacement for boats fitted from the factory with a 72 Ah battery of this format. - Good balance of capacity, cranking power and price. - Ready for starting outboard and inboard engines. - Sealed: no spills or gases in the locker. - Resistant to humidity and salt air. ### What the Exide EU72L is for The Exide EU72L is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 16 kg, EN taper post terminals and B13 hold-down. ### The Exide EU72L: Vintage range and conventional lead-acid technology The EU72L is part of the Exide **Vintage** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Dimensions, polarity and mounting The Exide EU72L is made in the 278 Γ— 175 Γ— 190 mm format and weighs 16 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B13 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Exide: the maker behind the EU72L Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### How to make it last longer On batteries with filler caps, check the electrolyte level and top up only with distilled water. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. ### Official warranty The Exide EU72L comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Shipping, delivery and returns Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### 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 our blog. 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€” with positive on the left 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. ### How many years does this battery last? Expected lifespan of the Exide EU72L 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 Exide EU72L battery? Dimensions (length Γ— width Γ— height) are 278Γ—175Γ—190 mm β€” also written as 278x175x190 mm and correspond to the European L3 case size 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. ### Which side is the positive terminal on this battery? Polarity: positive on the left. 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. ### Will the Exide EU72L 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 β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The EU72L typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Exide EU72L? 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. ## Equivalent batteries - [VARTA E12](https://baterias.com/gb/battery-varta-e12-12v-74ah-680a) - [TUDOR TB741](https://baterias.com/gb/battery-tudor-tb741-74ah-680a) - [EXIDE EB741](https://baterias.com/gb/battery-exide-eb741-12v-74ah-680a) - [KRONOBAT PB-74.1B](https://baterias.com/gb/best-price-battery-12v-74ah-pb-74_1b) ## 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· 2026-10-20*
