With **140 Ah** and **800 A** of cold cranking current (EN), the **Deta DG1406** from the **StartPRO** range is built for professional use in trucks, buses, tractors and heavy machinery. It measures 510 × 175 × 225 mm and the positive terminal on the right, the format sought by anyone replacing a 140 Ah battery in trucks.
- Heavy Duty construction for intensive professional use.
- Conventional lead-acid: the most proven and economical technology.
- Designed for 24 V installations with two batteries in series.
- 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**.

### Shipping, delivery 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.

## Frequently asked questions

### Why does my lorry have two batteries?

Most lorries, buses and tractors run on 24 V with two 12 V batteries connected in series. Always replace both at the same time and with the same model: if one is new and the other old, they become unbalanced and both last less.

### How long does the Deta DG1406 battery last?

Expected lifespan of the Deta DG1406 is 4 to 6 years in normal lorry use. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the dimensions of the Deta DG1406 battery?

Dimensions (length × width × height) are 510×175×225 mm — also written as 510x175x225 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### On which side is the positive of the DG1406 model?

Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Does this battery fit my truck?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DG1406 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Deta DG1406?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop trucks. See the "Equivalents" section to view recommended options at the same performance level.
