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. ### Vehicles compatible with the Tudor TB705 This battery appears as compatible in more than 453 vehicles from manufacturers such as Toyota, Nissan, LDV, Mitsubishi, Chevrolet and Dodge. If you are looking for a **battery for a Toyota** or Nissan with these dimensions, the TB705 is one of the usual replacement references. Models from Land Rover, Tata, Lexus, Daewoo, Chery, Pontiac, Ford and Bentley are added to that list. It is checked against 11 original-equipment references from different manufacturers. ### The Tudor TB705: Technica range and conventional lead-acid technology Within the Tudor catalogue, the **Technica** series groups the references designed for this use. The TB705 is the 70 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### 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. All the Tudor batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The Tudor TB705 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. ### How to make it last longer Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. ### Shipping, delivery and returns Order **before 6:00 pm** 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 **14 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 do I fit the TB705 model in my car? Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way (positive on the left) to match the polarity; 6) connect the positive (+) and finally the negative (−). With a 10 mm spanner, swapping in the Tudor TB705 takes 15 to 30 minutes on most cars; if the battery sits in the boot or under a seat, allow up to twice as long. For the detail, read our guide to replacing the car battery and, if in doubt, the owner's handbook or a main dealer. ### How long does the Tudor TB705 battery last? As a guide, you can expect the Tudor TB705 to last 4 to 6 years in regular car use without Start-Stop, although the real figure may be higher or lower. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance, plus the car itself and Start-Stop. Cold demands more at every start and intense heat evaporates the electrolyte. ### What are the measurements of the TB705 model? Measure your car's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 270x173x222 mm. Height is measured to the top of the terminals. ### On which side is the positive of the TB705 model? On the Tudor TB705, the polarity is positive on the left. To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering. ### Will the Tudor TB705 battery fit my car? Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your car is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). If our table and the car handbook disagree, go with what the manufacturer says. ### Which batteries are equivalent to the Tudor TB705? Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the TB705, 70 Ah (540 A cranking). The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop cars an EFB should not be replaced with a conventional battery. ### Tudor TB705 or Tudor TA755: which one to choose? It is the bigger sister of the TB705 in the same Tudor range. Compared with the TB705 it has 5 Ah more and 90 A of cold cranking more. It costs €30.40 more. If the tray takes the size, extra reserve never hurts; for a daily-driven petrol car the extra is not needed. ### Tudor TB705 or Exide EA755: which one to choose? Same case and same fitting as the TB705, from Exide. Compared with the TB705 it has 5 Ah more and 90 A of cold cranking more. It costs €15.80 more. If you want to save or the TB705 is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty. ## Equivalent batteries - [EXIDE EB705](https://baterias.com/gb/battery-exide-eb705-12v-70ah-540a) - [TUDOR TA755](https://baterias.com/gb/battery-tudor-ta755-75ah-630a) - [EXIDE EA755](https://baterias.com/gb/battery-exide-ea755-12v-75ah-630a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-08*
