Tudor TD2103T · Truck battery 12V 210Ah 800A GEL

Truck battery Tudor TD2103T 210Ah 800A 12V

The Tudor TD2103T truck battery is rated at 12 V, 210 Ah and 800 A of cold cranking current (EN), 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.

• 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.

Dimensions, polarity and mounting

The Tudor TD2103T is made in the 518 × 274 × 240 mm format 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 EN taper post 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 the Tudor TD2103T is for

With 210 Ah, the Tudor TD2103T cranks large-displacement diesel engines in the cold and powers tachograph, fridge and heater during rest stops. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 66 kg, EN taper post terminals and B00 hold-down.

Technology inside the Tudor TD2103T

Tudor builds the TD2103T to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.

Why choose Tudor batteries

Tudor has made batteries in Spain for more than a century and remains one of the brands most trusted by Spanish workshops for reliability and value. 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 Tudor TD2103T 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.

Care and maintenance

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.

Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.
