Fulmen FD2103 · Truck battery 12V 210Ah 1030A GEL

Truck battery Fulmen FD2103 Endurance+PRO Gel 210Ah 1,030A 12V

The Fulmen FD2103 truck battery is rated at 12 V, 210 Ah and 1,030 A of cold cranking current (EN) from the Endurance+PRO Gel range, and is prepared for trucks, buses, tractors and heavy machinery. It replaces the original battery without adaptation in trucks with a 518 × 274 × 240 mm format: same 210 Ah capacity and the positive terminal on the left.

In short: the Fulmen FD2103 (210 Ah, 1030 A, 518 × 274 × 240 mm, positive terminal on the left). Verified equivalent alternatives: Tudor TD2103 and Exide ED2103.

• GEL technology: gelled electrolyte, fully sealed and maintenance-free.
• Heavy Duty construction for intensive professional use.
• Powerful cold cranking for large-displacement diesel engines.
• Designed for 24 V installations with two batteries in series.

Dimensions, polarity and mounting

In terms of format, the Fulmen FD2103 measures 518 × 274 × 240 mm (length × width × height) and weighs 63.50 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. 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 the Fulmen FD2103 is for

The Fulmen FD2103 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 63.50 kg, 1 terminals and B00 hold-down.

The Fulmen FD2103: Endurance+PRO Gel range and GEL technology

The FD2103 is part of the Fulmen Endurance+PRO Gel 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 GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications.

Fulmen: the maker behind the FD2103

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.

Manufacturer's warranty

The Fulmen FD2103 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.

How to make it last longer

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.
