Vibration-resistant, withstands long cold-diesel cranks and deep discharges during parking with active loads (tachograph, refrigeration, heater). ### 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 800 A EN-1 πŸ“ Dimensions 518Γ—274Γ—240 mm βš™οΈ Technology GEL 🧭 Polarity Positive on the left βš–οΈ Weight 66 kg 🏷️ Model DETA Endurance+PRO Gel ## Description ## Truck battery Deta DD2103T Endurance+PRO Gel 210Ah 800A 12V 12*V* Voltage 210*Ah* Capacity 800*A* Cold cranking 66*kg* Weight The **Deta DD2103T truck battery** is rated at **12 V**, **210 Ah** and **800 A** of cold cranking current (EN) from the **Endurance+PRO Gel** range, and is prepared for 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. - Better tolerance to deep discharge than a conventional starter battery. - Powers tachograph, fridge and heater during rest stops. - Resistant to constant chassis vibration. - GEL: excellent resistance to deep discharge and long cycle life. ### What the Deta DD2103T is for The Deta DD2103T is designed for trucks, buses, tractors and heavy machinery. In 24 V installations with two batteries in series, replace both at the same time to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 66 kg, 1 terminals and B00 hold-down. ### Size, terminals and hold-down of the Deta DD2103T In terms of format, the Deta DD2103T measures 518 Γ— 274 Γ— 240 mm (length Γ— width Γ— height) and weighs 66 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. 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. ### Deta: the maker behind the DD2103T 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. ### The Deta DD2103T: Endurance+PRO Gel range and GEL technology Within the Deta catalogue, the **Endurance+PRO Gel** series groups the references designed for this use. The DD2103T is the 210 Ah model of that family, with the same performance as its siblings in other sizes. A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime. ### Usage and maintenance tips 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. ### Official warranty The Deta DD2103T 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**. ### Delivery times and returns Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] 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 ### Is this battery GEL? What is the typical use? 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 is the Deta DD2103T 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 long does the Deta DD2103T battery last? Expected lifespan of the Deta DD2103T 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 dimensions of the Deta DD2103T battery? 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. ### Will the Deta DD2103T 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 DD2103T typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Deta DD2103T? 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 - [EXIDE ED2103-T](https://baterias.com/gb/battery-exide-ed2103-t-12v-210ah-800a) - [VARTA N9](https://baterias.com/gb/battery-varta-n9-12v-225ah-1150a) - [VARTA N5](https://baterias.com/gb/battery-varta-n5-12v-220ah-1150a) - [VARTA LFD230](https://baterias.com/gb/battery-varta-lfd230-12v-230ah-1050a) - [VARTA C40](https://baterias.com/gb/battery-varta-c40-efb-12v-240ah-1200a) - [VARTA A1](https://baterias.com/gb/battery-varta-a1-12v-210ah-1200a) - [TUDOR TX2253](https://baterias.com/gb/battery-tudor-tx2253-225ah-1100a) ## 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*
