Fulmen FB621 · Car battery 12V 62Ah 540A

Car battery Fulmen FB621 Formula 62Ah 540A 12V

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.

In short: the Fulmen FB621 (62 Ah, 540 A, 242 × 175 × 190 mm, positive terminal on the left). 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 TB621 and Varta D43.

• 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.
