When is EFB used? Yes. The FL752 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 cars with basic Start-Stop (no regenerative braking). More affordable than an equivalent AGM, lifespan 4-6 years. ### Is the Fulmen FL752 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 check that the Fulmen FL752 battery fits my vehicle? Three ways: 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 for the FL752; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET). ### How is the Fulmen FL752 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 (−) 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 — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What warranty does the Fulmen FL752 battery have? This battery includes 2 years of official manufacturer warranty against manufacturing defects. It covers cell failures, internal short-circuits and abnormal capacity drops. It does NOT cover misuse (prolonged overcharging, inadequate charger, defective alternator). If the battery fails, we replace it at no cost after a technical inspection. ### How long does Fulmen FL752 delivery take? In mainland Spain and Portugal it arrives in 24 h if you order before 17:00 and the battery is in stock — it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships. ### How do I return the FL752 model if it doesn't fit? Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE — we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period. ### Where can I buy the Fulmen FL752 battery? At baterias.com — authorised distributor with real stock, 24h delivery in mainland Spain and Portugal if you order before 17:00, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point. ### What is the service life of the FL752 model? Expected lifespan of the Fulmen FL752 is 4 to 6 years in basic Start-Stop car 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 are the dimensions of the Fulmen FL752 battery? Dimensions (length × width × height) are 315×175×175 mm — also written as 315x175x175 mm and correspond to the European LB4 case size — 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. ### How much does the Fulmen FL752 battery weigh? It weighs 18,6 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre). ### How many Ah and CCA does this battery have? Nominal capacity 75 Ah[?cca: and [cold-cranking amps 730 A]] at 12 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer. ### Is the FL752 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 — we reply during business hours (Mon–Fri 9:00–18:00 CET). The FL752 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulmen FL752? 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 cars. See the "Equivalents" section to view recommended options at the same performance level. ### Is the FL752 model better than its equivalents from other brands? This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section. ### What do users say about the Fulmen FL752 battery? The product rating, when available, is shown on the product page next to the stars. You can also check our public Trustpilot profile at shop level (4.5/5 from 11,044+ verified reviews). Most-praised points: reliable cold start, lifespan above 5 years and fast delivery; most common complaints mention BMS-equipped cars that need OBD registration after fitting. ### What exactly is an EFB battery like the Fulmen FL752? 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 cars with basic Start-Stop (no regenerative braking): Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG, Ford EcoBoost. If your car 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 FL752 is original and meets EN 50342-6. ### Do I need to register the Fulmen FL752 on the car after installation? On most cars 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 car will still start correctly — the alternator just takes a few days to adjust the profile. The Fulmen FL752 ships factory-charged at 80-90% so you can use it straight after fitting. ## Equivalent batteries - [TUDOR TL752](https://baterias.com/gb/battery-tudor-tl752-75ah-730a) - [EXIDE EL752](https://baterias.com/gb/battery-exide-el752-12v-75ah-730a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-08-07*
