Deta DD2103 · Truck battery 12V 210Ah 1030A GEL

Truck battery Deta DD2103 Endurance+PRO Gel 210Ah 1,030A 12V

With 210 Ah and 1,030 A of cold cranking current (EN), the Deta DD2103 from the Endurance+PRO Gel range is built for professional use in trucks, buses, tractors and heavy machinery. Its 518 × 274 × 240 mm and the positive terminal on the left make it the exact replacement for the 210 Ah battery fitted as standard to many trucks.

In short: the Deta DD2103 (210 Ah, 1030 A, 518 × 274 × 240 mm, positive terminal on the left). Verified equivalent alternatives: Tudor TD2103 and Exide ED2103.

• Resistant to constant chassis vibration.
• GEL: excellent resistance to deep discharge and long cycle life.
• Better tolerance to deep discharge than a conventional starter battery.
• Powers tachograph, fridge and heater during rest stops.

Dimensions, polarity and mounting

In terms of format, the Deta DD2103 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. 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 Deta DD2103 is for

Designed for trucks, buses, tractors and heavy machinery, the Deta DD2103 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 63.50 kg, 1 terminals and B00 hold-down.

The Deta DD2103: Endurance+PRO Gel range and GEL technology

The DD2103 is part of the Deta 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.

Deta: the maker behind the DD2103

Deta combines German engineering with Exide's industrial capacity. Its Power, Senator and PowerPRO series cover everything from urban cars to construction machinery. We guarantee that every Deta arrives new, charged and with the manufacturer's full warranty.

Official warranty

The Deta DD2103 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

In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery.
