Fulmen FB450 · Car battery 12V 45Ah 330A

Car battery Fulmen FB450 Formula 45Ah 330A 12V

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.

In short: the Fulmen FB450 (45 Ah, 330 A, 220 × 135 × 225 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 TB450 and Varta B23.

• 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.

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.
