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 135 Ah C20 πŸ”‹ Cold cranking 1000 A EN-1 πŸ“ Dimensions 514Γ—175Γ—210 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 36 kg 🏷️ Model DETA StartPRO ## Description ## Truck battery Deta DG1355 StartPRO 135Ah 1,000A 12V 12*V* Voltage 135*Ah* Capacity 1,000*A* Cold cranking 36*kg* Weight The **Deta DG1355 truck battery** is rated at **12 V**, **135 Ah** and **1,000 A** of cold cranking current (EN) from the **StartPRO** range, and is prepared for trucks, buses, tractors and heavy machinery. It measures 514 Γ— 175 Γ— 210 mm and the positive terminal on the left, the format sought by anyone replacing a 135 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. ### Will it fit your current battery tray? It has external dimensions of 514 Γ— 175 Γ— 210 mm and weighs 36 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 B03 hold-down, 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. ### What the Deta DG1355 is for Designed for trucks, buses, tractors and heavy machinery, the Deta DG1355 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 36 kg and B03 hold-down. ### The Deta DG1355: StartPRO range and conventional lead-acid technology The DG1355 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. ### 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. ### Warranty and coverage The Deta DG1355 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**. ### How to make it last longer Keep the terminals clean and tight and the battery firmly secured against chassis vibration. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. ### 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 do I fit the DG1355 model in my truck? 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 our blog. 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€” with positive on the left 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 long does the Deta DG1355 battery last? Expected lifespan of the Deta DG1355 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 are the measurements of the DG1355 model? Dimensions (length Γ— width Γ— height) are 514Γ—175Γ—210 mm β€” also written as 514x175x210 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. ### What polarity does the Deta DG1355 battery have? Polarity: positive on the left. 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. ### Will the Deta DG1355 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 DG1355 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Deta DG1355? 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 - [TUDOR TG1355](https://baterias.com/gb/battery-tudor-tg1355-135ah-1000a) - [EXIDE EG1355](https://baterias.com/gb/battery-exide-eg1355-12v-135ah-1000a) - [KRONOBAT HD-135.3](https://baterias.com/gb/best-price-battery-12v-135ah-hd-135_3) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-22*
