The Fulmen FB450 from the Formula range delivers 45 Ah and 330 A of cold cranking current (EN) at 12 V: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It replaces the original battery without adaptation in cars with a 220 × 135 × 225 mm format: same 45 Ah capacity and the positive terminal on the right.

  • Conventional lead-acid: the most proven and economical technology.
  • Reliable cold starts, even after weeks without driving.
  • Direct replacement for the original battery in size and terminals.
  • Original-equipment build quality without the dealership price.

Dimensions, polarity and mounting

In terms of format, the Fulmen FB450 measures 220 × 135 × 225 mm (length × width × height) and weighs 12.50 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 B01 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.

Vehicles compatible with the Fulmen FB450

According to our database, the Fulmen FB450 equips more than 105 vehicles from brands such as Piaggio, Marcos, Renault, Hyundai, Nissan and Rover, among others. For anyone who needs to replace the battery in their Piaggio or Marcos, this Fulmen FB450 reproduces the original specifications. It also appears as a replacement in vehicles from Mazda, Suzuki, Ferrari, Carraro, Pasquali, Kubota, Bcs and Iseki, among other manufacturers. In our database it is cross-referenced against 31 original-equipment part numbers, which gives an idea of its real coverage.

The Fulmen FB450: Formula range and conventional lead-acid technology

The Formula is the Fulmen range the FB450 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

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.

Fulmen: the maker behind the FB450

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.

Manufacturer's warranty

The Fulmen FB450 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.

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. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.

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.

How to change the battery

Step-by-step guide to replace your car battery in 15-30 minutes (longer if the battery is under the seat or in the boot) without losing vehicle settings.

⏱ 15-30 min🛠 Tools: 10 mm wrench · Protective gloves
  1. Step 1. Prepare the vehicle

    Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.

  2. Step 2. Locate the battery

    Open the bonnet. The battery is usually in the engine bay, but in many modern cars it may be in the boot or under the passenger seat. Check the manual if you cannot find it.

  3. Step 3. Disconnect the negative (−) terminal

    Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.

  4. Step 4. Disconnect the positive (+) terminal

    Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.

  5. Step 5. Remove the old battery

    Loosen the bottom hold-down clamp with the same wrench. Lift the battery carefully (it can weigh 15-25 kg). Clean the tray with a brush and baking soda if there is corrosion.

  6. Step 6. Install the new battery

    Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.

  7. Step 7. Connect the cables

    Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.

  8. Step 8. Verify the engine starts

    Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.

Frequently asked questions

How do I fit the FB450 model in my car?

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 is the service life of the FB450 model?

Expected lifespan of the Fulmen FB450 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 dimensions of the Fulmen FB450 battery?

Dimensions (length × width × height) are 220×135×225 mm — also written as 220x135x225 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.

Will the Fulmen FB450 battery fit my car?

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 FB450 fits 105 verified vehicle versions in our database.

Which batteries are equivalent to the Fulmen FB450?

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.
