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 170 Ah C20 πŸ”‹ Cold cranking 950 A EN-1 πŸ“ Dimensions 514Γ—218Γ—210 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 42,5 kg 🏷️ Model DETA StartPRO ## Description ## Truck battery Deta DG1705 StartPRO 170Ah 950A 12V 12*V* Voltage 170*Ah* Capacity 950*A* Cold cranking 42.50*kg* Weight The **Deta DG1705 truck battery** is rated at **12 V**, **170 Ah** and **950 A** of cold cranking current (EN) from the **StartPRO** range, and is prepared for trucks, buses, tractors and heavy machinery. Measuring 514 Γ— 218 Γ— 210 mm and the positive terminal on the left, it is the direct replacement for trucks fitted from the factory with a 170 Ah battery of this format. - Powers tachograph, fridge and heater during rest stops. - Better tolerance to deep discharge than a conventional starter battery. - Good balance of capacity, cranking power and price. - Resistant to constant chassis vibration. ### Size, terminals and hold-down of the Deta DG1705 The Deta DG1705 is made in the 514 Γ— 218 Γ— 210 mm format and weighs 42.50 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 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. ### What the Deta DG1705 is for Designed for trucks, buses, tractors and heavy machinery, the Deta DG1705 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 42.50 kg and B03 hold-down. ### The Deta DG1705: StartPRO range and conventional lead-acid technology The DG1705 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. All the Deta batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Official warranty The Deta DG1705 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 In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. Keep the terminals clean and tight and the battery firmly secured against chassis vibration. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### How do I change this battery step by step? 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 DG1705 battery last? Expected lifespan of the Deta DG1705 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 514Γ—218Γ—210 mm β€” also written as 514x218x210 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. ### Which side is the positive terminal on this battery? 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. ### Is the DG1705 valid for my vehicle? 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 DG1705 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Deta DG1705? 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. ## 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· 2026-10-25*
