- Up to three times the cycles of a conventional battery.
- Compatible with regenerative braking and energy management (BMS).
- Withstands hundreds of starts a day without degrading.
- EFB technology: reinforced electrolyte for many more start cycles.

### What the Fulmen FL754 is for

In Start-Stop cars the battery works far harder than in a conventional car; the Fulmen FL754 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 19 kg, 1 terminals and B00 hold-down.

### Technology inside the Fulmen FL754

Fulmen builds the FL754 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
EFB (Enhanced Flooded Battery) technology reinforces the conventional lead-acid battery with a polyester separator and carbon additives in the plates. It withstands many more start cycles and partial discharges, making it ideal for basic Start-Stop and intensive use.

### Size, terminals and hold-down of the Fulmen FL754

In terms of format, the Fulmen FL754 measures 260 × 173 × 222 mm (length × width × height) and weighs 19 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 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.

### 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.

### How to make it last longer

If the vehicle only does very short trips, a periodic maintenance charge with an AGM/EFB-compatible charger greatly extends its life. A charger with an EFB or smart conventional mode is enough; avoid the high-voltage modes intended for AGM.

### Manufacturer's warranty

The Fulmen FL754 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.

### When you get it and how to return it

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 the FL754 model EFB? Which cars need it?

Yes. The FL754 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 FL754 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.

### What should I bear in mind when fitting this Start-Stop battery?

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 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 right 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. Also, the negative terminal usually carries a battery sensor (IBS): undo the cable at the terminal nut without removing the sensor. Always replace it with the same technology (AGM or EFB) or higher: a conventional battery wears out within months with Start-Stop.

### How long does the Fulmen FL754 battery last?

Expected lifespan of the Fulmen FL754 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 FL754 battery?

Dimensions (length × width × height) are 260×173×222 mm — also written as 260x173x222 mm — 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.

### What polarity does the Fulmen FL754 battery have?

Polarity: positive on the right. 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.

### Is the FL754 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 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The FL754 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### What are the equivalents of the FL754 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 cars. See the "Equivalents" section to view recommended options at the same performance level.

### What exactly is an EFB battery like the Fulmen FL754?

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 FL754 is original and meets EN 50342-6.

### Do I need to register the Fulmen FL754 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 FL754 ships factory-charged at 80-90% so you can use it straight after fitting.
