Fulmen FB442 · Car battery 12V 44Ah 420A

Car battery Fulmen FB442 Formula 44Ah 420A 12V

The Fulmen FB442 from the Formula range delivers 44 Ah and 420 A of cold cranking current (EN) at 12 V: the usual specification for passenger cars with conventional starting, without a Start-Stop system. Its 207 × 175 × 175 mm and the positive terminal on the right make it the exact replacement for the 44 Ah battery fitted as standard to many cars.

In short: the Fulmen FB442 (44 Ah, 420 A, 207 × 175 × 175 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 TB442 and Varta B18.

• Stable voltage for the vehicle electronics (ECU, sensors, climate control).
• Good balance of capacity, cranking power and price.
• Designed to last several years under normal daily use.
• Low self-discharge: copes with long stops without losing charge.

Will it fit your current battery tray?

It has external dimensions of 207 × 175 × 175 mm and weighs 10.60 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 B13 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.

The Fulmen FB442: Formula range and conventional lead-acid technology

The Formula is the Fulmen range the FB442 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 FB442

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Official warranty

The Fulmen FB442 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.

How to make it last longer

On batteries with filler caps, check the electrolyte level and top up only with distilled water. In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge.
