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. 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. ### What the Fulmen FL605 is for In Start-Stop cars the battery works far harder than in a conventional car; the Fulmen FL605 is built for that intensive cycling and to recharge quickly on the move. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 15.80 kg, 1 terminals and B00 hold-down. ### Technology inside the Fulmen FL605 Within the Fulmen catalogue, the FL605 is the 60 Ah model designed for this application. 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. ### Why choose Fulmen batteries 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. ### Warranty and coverage The Fulmen FL605 comes with the **manufacturer's official warranty**. To keep it valid, always fit the same technology as the original battery (AGM or EFB) and register the replacement if your vehicle requires it. ### Usage and maintenance tips If the vehicle only does very short trips, a periodic maintenance charge with an AGM/EFB-compatible charger greatly extends its life. In a Start-Stop car the battery is controlled by the ECU; after replacing it, the new battery may need to be registered so the system adjusts charging. ### Delivery times and returns Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is this battery EFB? When is it used? Yes. The FL605 is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. More affordable than an equivalent AGM and with more cycles than a conventional battery (though fewer than AGM), it is what cars with basic Start-Stop use, without regenerative braking. ### Is the Fulmen FL605 battery suitable for Start-Stop? Yes: being EFB, the Fulmen FL605 is designed for Start-Stop cars. EFB batteries cover basic Start-Stop (no regenerative braking). Registering it via OBD is advisable on most modern cars (the alternator then applies the optimum profile), but it works from the start. As a rule: EFB for basic Start-Stop, AGM when there is also regenerative braking (more cycles); in any case, what the car manufacturer specifies. ### How is the Fulmen FL605 battery fitted in a Start-Stop car? Start-Stop or BMS specifics: do not remove the IBS sensor on the negative terminal (just loosen the cable nut); after the swap, register the battery via OBD so the alternator charges with the right profile; and never step down in technology: if the car had AGM or EFB, the new one must be the same or better, as a conventional battery lasts only a few months. Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way (positive on the left) to match the polarity; 6) connect the positive (+) and finally the negative (−). For the detail, read our guide to replacing the car battery and, if in doubt, the owner's handbook or a main dealer. ### What is the service life of the FL605 model? As a guide, you can expect the Fulmen FL605 to last 4 to 6 years in basic Start-Stop car use, although the real figure may be higher or lower. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance, plus the car itself and Start-Stop. Cold demands more at every start and intense heat evaporates the electrolyte. ### What are the dimensions of the Fulmen FL605 battery? Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing. The Fulmen FL605 takes up 230×173×222 mm (length, width and height, terminals included). ### What polarity does the Fulmen FL605 battery have? On the Fulmen FL605, the polarity is positive on the left. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. ### Will the Fulmen FL605 battery fit my car? Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your car is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The car manufacturer's specifications always take priority over our tables. The FL605 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulmen FL605? A battery interchangeable with the Fulmen FL605 must match it on dimensions (230×173×222 mm), polarity (positive on the left), capacity (60 Ah) and cranking current (520 A). The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop cars an EFB should not be replaced with a conventional battery. ### Fulmen FL605 or Tudor TL605: which one to choose? Same case and same fitting as the FL605, from Tudor. Compared with the FL605 it has the same Ah and cranking power. It costs €107.20 more. If you want to save or the FL605 is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty. ### Fulmen FL605 or Exide EL605: which one to choose? It is the verified Exide equivalent for the FL605 tray. Compared with the FL605 it has the same Ah and cranking power. It costs €113.00 more. Decide by price, brand preference and availability: both fit and crank the same. ### Is this EFB enough for my Start-Stop car? The EFB (Enhanced Flooded Battery) is a reinforced flooded battery: plates with carbon and polyethylene additives and thicker grids, giving it more cycles than a conventional one; for cycles and deep discharges it still sits below an AGM. Its place is basic Start-Stop without regenerative braking, fitted from new in, for example, Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG or Ford EcoBoost. EFB from the factory? Stay with EFB; AGM is optional and only a marginal improvement. AGM from the factory? Then fit an AGM, because an EFB would fall short. This FL605 is an EFB. ### Do I need to register the Fulmen FL605 on the car after installation? It is not strictly necessary on most cars, because the alternator detects the change and adapts the charge. The advisable step is to register it via OBD: the charging profile is optimum from the first minute and the battery lasts longer, especially on brands with sophisticated BMS (BMW, Mercedes, Audi, Volvo, Land Rover). Any garage with an OBD scanner can do it in a few minutes. If you prefer to do it yourself: VCDS / Carista (VAG), Bimmercode (BMW) or iCarsoft. If you do not register the FL605, it will keep starting fine while the alternator adjusts the profile over a few days. ## Equivalent batteries - [TUDOR TL605](https://baterias.com/gb/battery-tudor-tl605-12v-60ah-520a) - [EXIDE EL605](https://baterias.com/gb/battery-exide-el605-12v-60ah-520a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
