Withstands constant chassis vibration, supports long cold-engine cranks and keeps auxiliary services running (tachograph, heater, refrigeration, GPS) during driver's mandatory rest stops. ### Why this truck battery? - **True Heavy Duty** built for intensive professional use - **Long cold-diesel cranks** reliable even in extreme cold - **Powers services at idle** tachograph, heater and lights with engine off πŸ”Œ Voltage 12 V ⚑ Capacity 120 Ah C20 πŸ”‹ Cold cranking 680 A EN-1 πŸ“ Dimensions 513Γ—189Γ—223 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 32,5 kg 🏷️ Model DETA StartPRO ## Description ## Truck battery Deta DG1203 StartPRO 120Ah 680A 12V 12*V* Voltage 120*Ah* Capacity 680*A* Cold cranking 32.50*kg* Weight The **Deta DG1203 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. It measures 513 Γ— 189 Γ— 223 mm and the positive terminal on the left, the format sought by anyone replacing a 120 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 DG1203 is for Designed for trucks, buses, tractors and heavy machinery, the Deta DG1203 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 32.50 kg and B00 hold-down. ### Dimensions, polarity and mounting In terms of format, the Deta DG1203 measures 513 Γ— 189 Γ— 223 mm (length Γ— width Γ— height) and weighs 32.50 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, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What Deta does differently 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. ### The Deta DG1203: StartPRO range and conventional lead-acid technology The **StartPRO** is the Deta range the DG1203 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use. ### Usage and maintenance tips Keep the terminals clean and tight and the battery firmly secured against chassis vibration. In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. ### Official warranty The Deta DG1203 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**. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How is the Deta DG1203 battery installed in the vehicle? In most trucks it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (βˆ’) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How many years does this battery last? Expected lifespan of the Deta DG1203 is 4 to 6 years in regular truck use without Start-Stop. 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 size is this battery? Dimensions (length Γ— width Γ— height) are 513Γ—189Γ—223 mm β€” also written as 513x189x223 mm β€” 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. ### 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 β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DG1203 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the DG1203 model? 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 β€” 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. ## Equivalent batteries - [VARTA M11](https://baterias.com/gb/battery-varta-m11-12v-154ah-1150a) - [VARTA LFD140](https://baterias.com/gb/battery-varta-lfd140-12v-140ah-800a) - [VARTA K7](https://baterias.com/gb/battery-varta-k7-12v-145ah-800a) - [VARTA I8](https://baterias.com/gb/battery-varta-i8-12v-120ah-680a) - [TUDOR TF1453](https://baterias.com/gb/battery-tudor-tf1453-145ah-900a) - [TUDOR TE1403](https://baterias.com/gb/battery-tudor-te1403-140ah-800a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-01*
