Delivers reliable cold-cranks even after weeks of inactivity and supports stable auxiliary loads (lights, climate control, infotainment). ### Why this car battery? - **Original-equipment quality** without dealership prices - **Lasts 4 to 6 years** buy once instead of twice - **Real human tech support** if you have any doubts before buying πŸ”Œ Voltage 12 V ⚑ Capacity 50 Ah C20 πŸ”‹ Cold cranking 450 A EN-1 πŸ“ Dimensions 207Γ—175Γ—190 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the right βš–οΈ Weight 12,1 kg 🏷️ Model FULMEN Formula ## Description ## Car battery Fulmen FB500 Formula 50Ah 450A 12V 12*V* Voltage 50*Ah* Capacity 450*A* Cold cranking 12.10*kg* Weight The **Fulmen FB500** from the **Formula** range delivers **50 Ah** and **450 A** of cold cranking current (EN) at **12 V**: the usual specification for passenger cars with conventional starting, without a Start-Stop system. Its 207 Γ— 175 Γ— 190 mm and the positive terminal on the right make it the exact replacement for the 50 Ah battery fitted as standard to many cars. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). - Good balance of capacity, cranking power and price. - Designed to last several years under normal daily use. - Low self-discharge: copes with long stops without losing charge. ### What the Fulmen FB500 is for With 50 Ah, the Fulmen FB500 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 12.10 kg, 1 terminals and B13 hold-down. ### The Fulmen FB500: Formula range and conventional lead-acid technology The FB500 is part of the Fulmen **Formula** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop. ### Size, terminals and hold-down of the Fulmen FB500 The Fulmen FB500 is made in the 207 Γ— 175 Γ— 190 mm format and weighs 12.10 kg. The positive terminal on the right 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 1 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### Fulmen: the maker behind the FB500 Fulmen is the historic French brand of the Exide group: batteries made on the same lines and with the same technology as original equipment, widely used by workshops across Europe. We guarantee that every Fulmen arrives new, charged and with the manufacturer's full warranty. ### Usage and maintenance tips Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge. In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. ### Warranty and coverage The Fulmen FB500 comes with the **manufacturer's official warranty** against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge. ### 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 is the Fulmen FB500 battery installed in the vehicle? In most cars 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 cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Fulmen FB500 battery last? Expected lifespan of the Fulmen FB500 is 4 to 6 years in regular car use without 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 FB500 model? Dimensions (length Γ— width Γ— height) are 207Γ—175Γ—190 mm β€” also written as 207x175x190 mm and correspond to the European L1 case size β€” following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Is the FB500 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 FB500 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulmen FB500? 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 cars. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [TUDOR TB500](https://baterias.com/gb/battery-tudor-tb500-50ah-450a) - [VARTA B19](https://baterias.com/gb/battery-varta-b19-12v-45ah-400a) - [EXIDE EB500](https://baterias.com/gb/battery-exide-eb500-12v-50ah-450a) - [EXIDE EC440](https://baterias.com/gb/battery-exide-ec440-12v-44ah-360a) - [TUDOR TC440](https://baterias.com/gb/battery-tudor-tc440-12v-44ah-360a) - [VARTA LFS52](https://baterias.com/gb/battery-varta-lfs52-12v-52ah-470a) - [VARTA C30](https://baterias.com/gb/battery-varta-c30-12v-54ah-530a) - [VARTA C22](https://baterias.com/gb/battery-varta-c22-12v-52ah-470a) - [TUDOR TL550](https://baterias.com/gb/battery-tudor-tl550-55ah-480a) ## 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· 2026-09-29*
