Car battery Fulmen FB454 Formula 45Ah 330A 12V
The Fulmen FB454 car battery is rated at 12 V, 45 Ah and 330 A of cold cranking current (EN) from the Formula range, and is designed for passenger cars with conventional starting, without a Start-Stop system. It replaces the original battery without adaptation in cars with a 237 × 127 × 227 mm format: same 45 Ah capacity and the positive terminal on the right.
In short: the Fulmen FB454 (45 Ah, 330 A, 237 × 127 × 227 mm, positive terminal on the right). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size. Verified equivalent alternatives: Tudor TB454 and Varta B32.
- 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.
What the Fulmen FB454 is for
With 45 Ah, the Fulmen FB454 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 11.40 kg and B00 hold-down.
The Fulmen FB454: Formula range and conventional lead-acid technology
The Formula is the Fulmen range the FB454 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.
In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.
Size, terminals and hold-down of the Fulmen FB454
It has external dimensions of 237 × 127 × 227 mm and weighs 11.40 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, 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. All the Fulmen batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
How to make it last longer
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.
Warranty and coverage
The Fulmen FB454 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.
Delivery times and returns
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
How is the Fulmen FB454 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 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.
What is the service life of the FB454 model?
Expected lifespan of the Fulmen FB454 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 measurements of the FB454 model?
Dimensions (length × width × height) are 237×127×227 mm — also written as 237x127x227 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 FB454 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.
Under which reference is the Fulmen FB454 listed in catalogues?
The manufacturer reference (MPN) is FB454 and its ETN code is 5451560333132 (short form 545 156 033), the European identifier used in spare-part catalogues. The EAN-13 barcode is 3661024044370. It belongs to the Varta Dynamic SLI range. Any of these codes identifies exactly this battery when requesting quotes or comparing prices.
Does this 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 FB454 fits 132 verified vehicle versions in our database.
Which interchangeable batteries are there for this one?
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.
