Fulmen FB704 Formula · Car battery 70Ah 540A

Car battery Fulmen FB704 Formula 70Ah 540A 12V

The Fulmen FB704 from the Formula range delivers 70 Ah and 540 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 270 × 173 × 222 mm format: same 70 Ah capacity and the positive terminal on the right.

In short: the Fulmen FB704 (70 Ah, 540 A, 270 × 173 × 222 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 TB704 and Exide EB704.

• 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.

What the Fulmen FB704 is for

The Fulmen FB704 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 16.10 kg and Korean B1+B6 hold-down.

The Fulmen FB704: Formula range and conventional lead-acid technology

Within the Fulmen catalogue, the Formula series groups the references designed for this use. The FB704 is the 70 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.

Dimensions, polarity and mounting

In terms of format, the Fulmen FB704 measures 270 × 173 × 222 mm (length × width × height) and weighs 16.10 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 Korean B1+B6 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.

What Fulmen does differently

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. All the Fulmen batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

How to make it last longer

Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. 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.

Warranty and coverage

The Fulmen FB704 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.
