Truck battery Deta DG1206 StartPRO 120Ah 680A 12V

The Deta DG1206 truck battery is rated at 12 V, 120 Ah and 680 A of cold cranking current (EN) from the StartPRO range, and is prepared for trucks, buses, tractors and heavy machinery. Its 510 × 175 × 225 mm and the positive terminal on the right make it the exact replacement for the 120 Ah battery fitted as standard to many trucks.

In short: the Deta DG1206 (120 Ah, 680 A, 510 × 175 × 225 mm, positive terminal on the right). Verified equivalent alternatives: Tudor TG1406 and Exide EG1406.

• Resistant to constant chassis vibration.
• Good balance of capacity, cranking power and price.
• Better tolerance to deep discharge than a conventional starter battery.
• Powers tachograph, fridge and heater during rest stops.

What the Deta DG1206 is for

Designed for trucks, buses, tractors and heavy machinery, the Deta DG1206 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 31.80 kg, 1 terminals and B03 hold-down.

Size, terminals and hold-down of the Deta DG1206

It has external dimensions of 510 × 175 × 225 mm and weighs 31.80 kg. The positive terminal on the right 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 B03 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.

The Deta DG1206: StartPRO range and conventional lead-acid technology

The DG1206 is part of the Deta StartPRO range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

Deta: the maker behind the DG1206

Deta is the German brand of the Exide group: batteries built with original-equipment technology and a very complete range for cars, Start-Stop, trucks, motorcycles and leisure. We guarantee that every Deta arrives new, charged and with the manufacturer's full warranty.

Warranty and coverage

The Deta DG1206 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

On batteries with filler caps, check the electrolyte level and top up only with distilled water. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery.
