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 210 Ah C20 πŸ”‹ Cold cranking 1030 A EN-1 πŸ“ Dimensions 518Γ—274Γ—240 mm βš™οΈ Technology GEL 🧭 Polarity Positive on the left βš–οΈ Weight 63,5 kg 🏷️ Model DETA Endurance+PRO Gel ## Description ## Truck battery Deta DD2103 Endurance+PRO Gel 210Ah 1,030A 12V 12*V* Voltage 210*Ah* Capacity 1,030*A* Cold cranking 63.50*kg* Weight With **210 Ah** and **1,030 A** of cold cranking current (EN), the **Deta DD2103** from the **Endurance+PRO Gel** range is built for professional use in trucks, buses, tractors and heavy machinery. Its 518 Γ— 274 Γ— 240 mm and the positive terminal on the left make it the exact replacement for the 210 Ah battery fitted as standard to many trucks. - Resistant to constant chassis vibration. - GEL: excellent resistance to deep discharge and long cycle life. - Better tolerance to deep discharge than a conventional starter battery. - Powers tachograph, fridge and heater during rest stops. ### Dimensions, polarity and mounting In terms of format, the Deta DD2103 measures 518 Γ— 274 Γ— 240 mm (length Γ— width Γ— height) and weighs 63.50 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 and 1 terminals, 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 DD2103 is for Designed for trucks, buses, tractors and heavy machinery, the Deta DD2103 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 63.50 kg, 1 terminals and B00 hold-down. ### The Deta DD2103: Endurance+PRO Gel range and GEL technology The DD2103 is part of the Deta **Endurance+PRO Gel** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications. ### Deta: the maker behind the DD2103 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. ### Official warranty The Deta DD2103 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. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. ### Delivery times and returns 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 ### Is the Deta DD2103 a GEL battery? What is GEL used for? Yes, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger β€” max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years. ### 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. ### What is the service life of the DD2103 model? Expected lifespan of the Deta DD2103 is 6 to 10 years in cyclic use (marine, caravan, solar) with controlled discharges. 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 DD2103 model? Dimensions (length Γ— width Γ— height) are 518Γ—274Γ—240 mm β€” also written as 518x274x240 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. ### On which side is the positive of the DD2103 model? 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 DD2103 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 DD2103 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Deta DD2103? 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 TD2103](https://baterias.com/gb/battery-tudor-td2103-210ah-1050a) - [EXIDE ED2103](https://baterias.com/gb/battery-exide-ed2103-12v-210ah-1050a) - [EXIDE ED2103-T](https://baterias.com/gb/battery-exide-ed2103-t-12v-210ah-800a) ## 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· 2026-10-21*
