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 142 Ah C20 πŸ”‹ Cold cranking 850 A EN-1 πŸ“ Dimensions 345Γ—175Γ—290 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 35,1 kg 🏷️ Model TUDOR Power Pro (HDX) ## Description ## Truck battery Tudor TF1421 PRO (Hdx) 142Ah 850A 12V 12*V* Voltage 142*Ah* Capacity 850*A* Cold cranking 35.10*kg* Weight The **Tudor TF1421 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. It replaces the original battery without adaptation in trucks with a 345 Γ— 175 Γ— 290 mm format: same 142 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. - Conventional lead-acid: the most proven and economical technology. - Heavy Duty construction for intensive professional use. ### Will it fit your current battery tray? The Tudor TF1421 is made in the 345 Γ— 175 Γ— 290 mm format and weighs 35.10 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. 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 TF1421 is for The Tudor TF1421 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 TF1421: PRO (Hdx) range and conventional lead-acid technology The **PRO (Hdx)** is the Tudor range the TF1421 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use. ### Tudor: the maker behind the TF1421 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. All the Tudor batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The Tudor TF1421 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**. ### Usage and maintenance tips During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### Shipping, delivery 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 ### How is the Tudor TF1421 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 Tudor TF1421 battery last? Expected lifespan of the Tudor TF1421 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 345Γ—175Γ—290 mm β€” also written as 345x175x290 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. ### Is the TF1421 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 TF1421 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the TF1421 model? 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. ## Reviews - **Average rating**: 4.73 / 5 (35 reviews) ## 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· 2026-10-02*
