Fulmen FB456 · Car battery 12V 45Ah 330A

Car battery Fulmen FB456 Formula 45Ah 330A 12V

The Fulmen FB456 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. Its 237 × 127 × 227 mm and the positive terminal on the right make it the exact replacement for the 45 Ah battery fitted as standard to many cars.

In short: the Fulmen FB456 (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 TB456 and Varta B31.

• 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 FB456 is for

With 45 Ah, the Fulmen FB456 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.

Will it fit your current battery tray?

The Fulmen FB456 is made in the 237 × 127 × 227 mm format 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

With more than a century of history, Fulmen offers complete ranges for cars, trucks, motorcycles and leisure with the industrial quality of the Exide group. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The Fulmen FB456: Formula range and conventional lead-acid technology

The FB456 is part of the Fulmen Formula range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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.

Usage and maintenance tips

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. 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 FB456 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.
