Delivers the cranking amps the engine needs in cold weather and keeps stable voltage for modern car loads (ECU, sensors, climate control, infotainment). ## Why this car battery? - **Original-equipment quality** without dealership prices - **Lasts 4 to 6 years** buy once instead of twice - **Real human tech support** if you have any doubts before buying πŸ”Œ Voltage 12 V ⚑ Capacity 68 Ah C20 πŸ”‹ Cold cranking 650 A EN-1 πŸ“ Dimensions 277Γ—175Γ—190 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 17 kg 🏷️ Model TUDOR HIGH TECH ## Description ## Car battery Tudor TA681 High Tech 68Ah 650A 12V 12*V* Voltage 68*Ah* Capacity 650*A* Cold cranking 17*kg* Weight With **68 Ah** at **12 V** and **650 A** of cold cranking current (EN), the **Tudor TA681** from the **High Tech** range is a starter battery built for passenger cars with conventional starting, without a Start-Stop system. Measuring 277 Γ— 175 Γ— 190 mm and the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 68 Ah battery of this format. - Good balance of capacity, cranking power and price. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). - Low self-discharge: copes with long stops without losing charge. - Designed to last several years under normal daily use. ### Dimensions, polarity and mounting The Tudor TA681 is made in the 277 Γ— 175 Γ— 190 mm format and weighs 17 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 B13 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### What the Tudor TA681 is for The Tudor TA681 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 17 kg, EN taper post terminals and B13 hold-down. ### The Tudor TA681: High Tech range and conventional lead-acid technology The **High Tech** is the Tudor range the TA681 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. ### Why choose Tudor batteries 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Official warranty The Tudor TA681 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 On batteries with filler caps, check the electrolyte level and top up only with distilled water. 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. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### How do I change this battery step by step? 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 our blog. 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€” with positive on the left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Tudor TA681 battery last? Expected lifespan of the Tudor TA681 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 size is this battery? Dimensions (length Γ— width Γ— height) are 277Γ—175Γ—190 mm β€” also written as 277x175x190 mm and correspond to the European L3 case size β€” 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. ### Which side is the positive terminal on this battery? Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ### Is the TA681 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 TA681 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the TA681 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 cars. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [TUDOR TB741](https://baterias.com/gb/battery-tudor-tb741-74ah-680a) - [VARTA E12](https://baterias.com/gb/battery-varta-e12-12v-74ah-680a) - [EXIDE EB741](https://baterias.com/gb/battery-exide-eb741-12v-74ah-680a) - [KRONOBAT PB-74.1B](https://baterias.com/gb/best-price-battery-12v-74ah-pb-74_1b) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-25*
