Car battery Fulmen FA456 Formula Xtreme 45Ah 390A 12V

With 45 Ah at 12 V and 390 A of cold cranking current (EN), the Fulmen FA456 from the Formula Xtreme range is a starter battery built 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 FA456 (45 Ah, 390 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 TA456 and Exide EA456.

• 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.

Dimensions, polarity and mounting

It has external dimensions of 237 × 127 × 227 mm and weighs 11.80 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, 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 FA456: Formula Xtreme range and conventional lead-acid technology

Within the Fulmen catalogue, the Formula Xtreme series groups the references designed for this use. The FA456 is the 45 Ah model of that family, with the same performance as its siblings in other sizes.

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.

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 FA456 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.
