12*V* Voltage
62*Ah* Capacity
540*A* Cold cranking
14.40*kg* Weight

With **62 Ah** at **12 V** and **540 A** of cold cranking current (EN), the **Fulmen FB621** from the **Formula** range is a starter battery built for passenger cars with conventional starting, without a Start-Stop system. Its 242 × 175 × 190 mm and the positive terminal on the left make it the exact replacement for the 62 Ah battery fitted as standard to many cars.
- Designed to last several years under normal daily use.
- Low self-discharge: copes with long stops without losing charge.
- Stable voltage for the vehicle electronics (ECU, sensors, climate control).
- Good balance of capacity, cranking power and price.

### What the Fulmen FB621 is for

Designed for passenger cars with conventional starting, without a Start-Stop system, the Fulmen FB621 is the direct replacement when your vehicle uses a 62 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 14.40 kg and B13 hold-down.

### Will it fit your current battery tray?

The Fulmen FB621 is made in the 242 × 175 × 190 mm format and weighs 14.40 kg. 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 B13 hold-down, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

### The Fulmen FB621: Formula range and conventional lead-acid technology

Within the Fulmen catalogue, the **Formula** series groups the references designed for this use. The FB621 is the 62 Ah model of that family, with the same performance as its siblings in other sizes.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

### What Fulmen does differently

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 FB621 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.

### Care and maintenance

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.

### Shipping, delivery and returns

Order **before [[ks:cutoff]]** 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 **[[ks:return_days]] 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 FB621 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.

### How long does the Fulmen FB621 battery last?

Expected lifespan of the Fulmen FB621 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 size is this battery?

Dimensions (length × width × height) are 242×175×190 mm — also written as 242x175x190 mm and correspond to the European L2 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.

### Under which reference is the Fulmen FB621 listed in catalogues?

The manufacturer reference (MPN) is FB621 and its ETN code is 5601270543132 (short form 560 127 054), the European identifier used in spare-part catalogues. The EAN-13 barcode is 3661024044547. It belongs to the Varta Dynamic SLI range. Any of these codes identifies exactly this battery when requesting quotes or comparing prices.

### Is the FB621 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 16:40–18:00 (Spanish time, CET)). The FB621 fits 260 verified vehicle versions in our database.

### What are the equivalents of the FB621 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.
