Fulmen FB504 Formula · Car battery 50Ah 360A

Car battery Fulmen FB504 Formula 50Ah 360A 12V

The Fulmen FB504 from the Formula range delivers 50 Ah and 360 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 200 × 173 × 222 mm format: same 50 Ah capacity and the positive terminal on the right.

In short: the Fulmen FB504 (50 Ah, 360 A, 200 × 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 TB504 and Exide EB504.

• 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

The Fulmen FB504 is made in the 200 × 173 × 222 mm format and weighs 12.90 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 hold-down and 1 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

What the Fulmen FB504 is for

With 50 Ah, the Fulmen FB504 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 12.90 kg, 1 terminals and Korean B1 hold-down.

The Fulmen FB504: Formula range and conventional lead-acid technology

The Formula is the Fulmen range the FB504 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.

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.

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.

Warranty and coverage

The Fulmen FB504 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

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

Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe.
