• Powerful cold cranking for large-displacement diesel engines.

What the Deta DG1406 is for

Designed for trucks, buses, tractors and heavy machinery, the Deta DG1406 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 33.50 kg and B03 hold-down.

Dimensions, polarity and mounting

In terms of format, the Deta DG1406 measures 510 × 175 × 225 mm (length × width × height) and weighs 33.50 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, 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.

Deta: the maker behind the DG1406

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. All the Deta batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Deta DG1406: StartPRO range and conventional lead-acid technology

The DG1406 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.

The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

How to make it last longer

During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. Keep the terminals clean and tight and the battery firmly secured against chassis vibration.

Warranty and coverage

The Deta DG1406 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.
