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 🔌 Voltage 12 V ⚡ Capacity 142 Ah C20 🔋 Cold cranking 850 A EN-1 📏 Dimensions 349×175×290 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ⚖️ Weight 35,1 kg 🏷️ Model TUDOR Power Pro (HDX) ## Description ## Truck battery Tudor TF1420 PRO (Hdx) 142Ah 850A 12V 12*V* Voltage 142*Ah* Capacity 850*A* Cold cranking 35.10*kg* Weight The **Tudor TF1420 truck battery** is rated at **12 V**, **142 Ah** and **850 A** of cold cranking current (EN) from the **PRO (Hdx)** range, and is prepared for trucks, buses, tractors and heavy machinery. Measuring 349 × 175 × 290 mm and the positive terminal on the right, it is the direct replacement for trucks fitted from the factory with a 142 Ah battery of this format. - Good balance of capacity, cranking power and price. - Resistant to constant chassis vibration. - Powers tachograph, fridge and heater during rest stops. - Better tolerance to deep discharge than a conventional starter battery. ### Size, terminals and hold-down of the Tudor TF1420 The Tudor TF1420 is made in the 349 × 175 × 290 mm format and weighs 35.10 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. 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 TF1420 is for The Tudor TF1420 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 35.10 kg. ### The Tudor TF1420: PRO (Hdx) range and conventional lead-acid technology The TF1420 is part of the Tudor **PRO (Hdx)** 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 Tudor does differently Tudor is Spain's historic battery brand, today part of the Exide group. Its car, truck, motorcycle and leisure ranges are built with the same technology and controls as the group's original-equipment references. We guarantee that every Tudor arrives new, charged and with the manufacturer's full warranty. ### Warranty and coverage The Tudor TF1420 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 During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. ### When you get it and how to return it Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### How is the Tudor TF1420 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 TF1420 model? Expected lifespan of the Tudor TF1420 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 dimensions of the Tudor TF1420 battery? Dimensions (length × width × height) are 349×175×290 mm — also written as 349x175x290 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. ### Is the TF1420 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 — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The TF1420 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Tudor TF1420? 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. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-09*
