What the Fulmen FJ1805 is for

The Fulmen FJ1805 is designed for trucks, buses, tractors and heavy machinery. In 24 V installations with two batteries in series, replace both at the same time to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 43 kg, 1 terminals and B03 hold-down.

Dimensions, polarity and mounting

The Fulmen FJ1805 is made in the 510 × 218 × 225 mm format and weighs 43 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 B03 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.

Fulmen: the maker behind the FJ1805

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 FJ1805: PowerPRO y Construction range and conventional lead-acid technology

The PowerPRO y Construction is the Fulmen range the FJ1805 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.

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.

Care and maintenance

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing.

Warranty and coverage

The Fulmen FJ1805 comes with the manufacturer's official warranty against manufacturing defects. An important note for commercial vehicles: most trucks use two batteries connected in series (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace both at the same time.
