Car battery Fulmen FB505 Formula 50Ah 360A 12V

With 50 Ah at 12 V and 360 A of cold cranking current (EN), the Fulmen FB505 from the Formula range is a starter battery built for passenger cars with conventional starting, without a Start-Stop system. Measuring 200 × 173 × 222 mm and the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 50 Ah battery of this format.

In short: the Fulmen FB505 (50 Ah, 360 A, 200 × 173 × 222 mm, positive terminal on the left). 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 TB505 and Exide EB505.

• Good balance of capacity, cranking power and price.
• Stable voltage for the vehicle electronics (ECU, sensors, climate control).
• Low self-discharge: copes with long stops without losing charge.
• Designed to last several years under normal daily use.

What the Fulmen FB505 is for

Designed for passenger cars with conventional starting, without a Start-Stop system, the Fulmen FB505 is the direct replacement when your vehicle uses a 50 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. 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.

Will it fit your current battery tray?

The Fulmen FB505 is made in the 200 × 173 × 222 mm format and weighs 12.90 kg. The positive terminal on the left 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. 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 FB505: Formula range and conventional lead-acid technology

The Formula is the Fulmen range the FB505 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.

How to make it last longer

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. 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.

Official warranty

The Fulmen FB505 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.
