Deta DD2103T · Truck battery 12V 210Ah 800A GEL

Truck battery Deta DD2103T Endurance+PRO Gel 210Ah 800A 12V

The Deta DD2103T 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. 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 DD2103T (210 Ah, 800 A, 518 × 274 × 240 mm, positive terminal on the left). Verified equivalent alternatives: Exide ED2103-T and Exide ED2103.

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

What the Deta DD2103T is for

The Deta DD2103T 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.

Size, terminals and hold-down of the Deta DD2103T

In terms of format, the Deta DD2103T measures 518 × 274 × 240 mm (length × width × height) 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. 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.

Deta: the maker behind the DD2103T

Deta combines German engineering with Exide's industrial capacity. Its Power, Senator and PowerPRO series cover everything from urban cars to construction machinery. All the Deta batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Deta DD2103T: Endurance+PRO Gel range and GEL technology

Within the Deta catalogue, the Endurance+PRO Gel series groups the references designed for this use. The DD2103T 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.

Usage and maintenance tips

In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. Keep the terminals clean and tight and the battery firmly secured against chassis vibration.

Official warranty

The Deta DD2103T 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.
