It replaces the original battery without adaptation in cars with a 306 × 173 × 222 mm format: same 90 Ah capacity and the positive terminal on the left. - Direct replacement for the original battery in size and terminals. - Original-equipment build quality without the dealership price. - Conventional lead-acid: the most proven and economical technology. - Reliable cold starts, even after weeks without driving. ### What the Tudor TC905 is for With 90 Ah, the Tudor TC905 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 19.90 kg, EN taper post terminals and Korean B1 hold-down. ### The Tudor TC905: Standard range and conventional lead-acid technology Within the Tudor catalogue, the **Standard** series groups the references designed for this use. The TC905 is the 90 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### Size, terminals and hold-down of the Tudor TC905 In terms of format, the Tudor TC905 measures 306 × 173 × 222 mm (length × width × height) and weighs 19.90 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 Korean B1 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 Tudor does differently 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. ### Care and maintenance In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. ### Manufacturer's warranty The Tudor TC905 comes with the **manufacturer's official warranty** against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge. ### 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 TC905 battery installed in the vehicle? In most cars 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 cars 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 TC905 model? Expected lifespan of the Tudor TC905 is 4 to 7 years in regular use (depends on technology and climate). 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 TC905 battery? Dimensions (length × width × height) are 306×173×222 mm — also written as 306x173x222 mm — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Is the TC905 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 TC905 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Tudor TC905? 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 cars. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [EXIDE EC905](https://baterias.com/gb/battery-exide-ec905-12v-90ah-680a) ## 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 · 2026-10-12*
