Fulmen FD2103T Endurance+Pro GEL · Truck battery 210Ah 800A

Truck battery Fulmen FD2103T Endurance+PRO Gel 210Ah 800A 12V

The Fulmen FD2103T truck battery is rated at 12 V, 210 Ah and 800 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 FD2103T (210 Ah, 800 A, 518 × 274 × 240 mm, positive terminal on the left). Verified equivalent alternatives: Exide ED2103-T and Exide ED2103.

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

What the Fulmen FD2103T is for

The Fulmen FD2103T 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 66 kg, 1 terminals and B00 hold-down.

Dimensions, polarity and mounting

It has external dimensions of 518 × 274 × 240 mm and weighs 66 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. 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.

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. We guarantee that every Fulmen arrives new, charged and with the manufacturer's full warranty.

The Fulmen FD2103T: Endurance+PRO Gel range and GEL technology

Within the Fulmen catalogue, the Endurance+PRO Gel series groups the references designed for this use. The FD2103T is the 210 Ah model of that family, with the same performance as its siblings in other sizes.

A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.

How to make it last longer

In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.

Warranty and coverage

The Fulmen FD2103T 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.
