• Designed for 24 V installations with two batteries in series.

What the Fulmen FJ1723 is for

Designed for trucks, buses, tractors and heavy machinery, the Fulmen FJ1723 withstands constant chassis vibration and discharges during stops with active loads. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 48.80 kg, 1 terminals and B00 hold-down.

Size, terminals and hold-down of the Fulmen FJ1723

The Fulmen FJ1723 is made in the 513 × 223 × 223 mm format and weighs 48.80 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 B00 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 FJ1723

Fulmen is the historic French brand of the Exide group: batteries made on the same lines and with the same technology as original equipment, widely used by workshops across Europe. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The Fulmen FJ1723: PowerPRO y Construction range and conventional lead-acid technology

The FJ1723 is part of the Fulmen PowerPRO y Construction range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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.

Usage and maintenance tips

During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Warranty and coverage

The Fulmen FJ1723 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.
