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 ⚡ Capacity 210 Ah C20 🔋 Cold cranking 800 A EN-1 📏 Dimensions 518×274×240 mm ⚙️ Technology GEL 🧭 Polarity Positive on the left ⚖️ Weight 66 kg ## Description ## Truck battery Tudor TD2103T 210Ah 800A 12V 12*V* Voltage 210*Ah* Capacity 800*A* Cold cranking 66*kg* Weight The **Tudor TD2103T truck battery** is rated at **12 V**, **210 Ah** and **800 A** of cold cranking current (EN), and is prepared for trucks, buses, tractors and heavy machinery. It replaces the original battery without adaptation in trucks with a 518 × 274 × 240 mm format: same 210 Ah capacity and the positive terminal on the left. - Powerful cold cranking for large-displacement diesel engines. - Designed for 24 V installations with two batteries in series. - GEL technology: gelled electrolyte, fully sealed and maintenance-free. - Heavy Duty construction for intensive professional use. ### Dimensions, polarity and mounting The Tudor TD2103T is made in the 518 × 274 × 240 mm format 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 EN taper post 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 Tudor TD2103T is for With 210 Ah, the Tudor TD2103T cranks large-displacement diesel engines in the cold and powers tachograph, fridge and heater during rest stops. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 66 kg, EN taper post terminals and B00 hold-down. ### Technology inside the Tudor TD2103T Tudor builds the TD2103T to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM. ### Why choose Tudor batteries Tudor has made batteries in Spain for more than a century and remains one of the brands most trusted by Spanish workshops for reliability and value. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Manufacturer's warranty The Tudor TD2103T 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**. ### Care and maintenance Keep the terminals clean and tight and the battery firmly secured against chassis vibration. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. ### 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 TD2103T model a gel battery? Where is it used? 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 — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years. ### How is the Tudor TD2103T 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 (−) 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 — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). 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 TD2103T model? Expected lifespan of the Tudor TD2103T 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 Tudor TD2103T battery? Dimensions (length × width × height) are 518×274×240 mm — also written as 518x274x240 mm — 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 — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The TD2103T typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Tudor TD2103T? 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 — 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 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 — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-28*
