It replaces the original battery without adaptation in trucks with a 513 × 223 × 223 mm format: same 180 Ah capacity and the positive terminal on the left. - EFB technology: reinforced electrolyte for many more start cycles. - Heavy Duty construction for intensive professional use. - Powerful cold cranking for large-displacement diesel engines. - Designed for 24 V installations with two batteries in series. ### What the Fulmen FX1803 is for The Fulmen FX1803 is designed for trucks, buses, tractors and heavy machinery. In 24 V installations with two batteries in series, replace both at the same time to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 46.10 kg, 1 terminals and B00 hold-down. ### Dimensions, polarity and mounting It has external dimensions of 513 × 223 × 223 mm and weighs 46.10 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 B00 hold-down and 1 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. ### The Fulmen FX1803: EndurancePRO EFB range and EFB technology The FX1803 is part of the Fulmen **EndurancePRO EFB** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. An EFB is a reinforced flooded battery: its plates retain the active material better and tolerate the cycling imposed by a simple Start-Stop system, at a lower cost than an AGM. ### What Fulmen does differently With more than a century of history, Fulmen offers complete ranges for cars, trucks, motorcycles and leisure with the industrial quality of the Exide group. We guarantee that every Fulmen arrives new, charged and with the manufacturer's full warranty. ### Official warranty The Fulmen FX1803 comes with the **manufacturer's official warranty** against manufacturing defects. An important note for commercial vehicles: most trucks use **two batteries connected in series** (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace **both at the same time**. ### How to make it last longer In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. A charger with an EFB or smart conventional mode is enough; avoid the high-voltage modes intended for AGM. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the Fulmen FX1803 an EFB battery? When is EFB used? Yes. The FX1803 is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. Withstands more cycles than a conventional but fewer than an AGM. Fitted to trucks with basic Start-Stop (no regenerative braking). More affordable than an equivalent AGM, lifespan 4-6 years. ### Is the Fulmen FX1803 battery suitable for Start-Stop? Yes. As EFB technology it is designed for Start-Stop vehicles. EFB batteries cover basic Start-Stop (no regenerative braking). EFB is recommended for basic Start-Stop; AGM is recommended when regenerative braking is also present, thanks to its higher cycle capability. It works straight out of the box — on most modern vehicles registering the battery via OBD is recommended so the alternator automatically applies the optimal charging profile. ### How do I change this battery step by step? In most trucks 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 (−) 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 — with positive on the left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks 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 FX1803 model? Expected lifespan of the Fulmen FX1803 is 4 to 6 years in basic Start-Stop truck use. 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 × width × height) are 513×223×223 mm — also written as 513x223x223 mm — following the European DIN standard. Always measure the space in your truck 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 FX1803 model? 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 Fulmen FX1803 battery fit my truck? 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 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The FX1803 fits 141 verified vehicle versions in our database. ### What are the equivalents of the FX1803 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 trucks. See the "Equivalents" section to view recommended options at the same performance level. ### What exactly is an EFB battery like the Fulmen FX1803? An EFB (Enhanced Flooded Battery) is a flooded lead-acid battery reinforced with plate additives (carbon and polyethylene) and thicker grids. It withstands twice the cycles of a conventional battery and handles deep discharges better, but less than an AGM. It is the original fitment on trucks with basic Start-Stop (no regenerative braking): Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG, Ford EcoBoost. If your truck came with EFB from the factory, this is the correct battery — upgrading to AGM is optional (marginal improvement). If it came with AGM, EFB may fall short: better fit AGM. The Fulmen FX1803 is original and meets EN 50342-6. ### Will my truck recognise the new battery automatically? On most trucks it is not strictly necessary — the alternator detects the new battery and adapts the charge automatically. It is recommended to register the battery via OBD so that the alternator applies the optimal charging profile from the first minute and extends the battery life as much as possible (especially on brands with sophisticated BMS: BMW, Mercedes, Audi, Volvo, Land Rover). Any workshop with an OBD scanner (~10-15 € labour) does it in 5 minutes. DIY apps: VCDS / Carista (VAG), Bimmercode (BMW), iCarsoft. If you do not register, the truck will still start correctly — the alternator just takes a few days to adjust the profile. The Fulmen FX1803 ships factory-charged at 80-90% so you can use it straight after fitting. ## Compatible vehicles This battery fits 141 vehicles.
