- 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 TA456 is for
Designed for passenger cars with conventional starting, without a Start-Stop system, the Tudor TA456 is the direct replacement when your vehicle uses a 45 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 11.80 kg.
Size, terminals and hold-down of the Tudor TA456
It has external dimensions of 237 × 127 × 227 mm and weighs 11.80 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.
Why choose Tudor batteries
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. All the Tudor batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
The Tudor TA456: High Tech range and conventional lead-acid technology
The TA456 is part of the Tudor High Tech range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.
Care and maintenance
Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. On batteries with filler caps, check the electrolyte level and top up only with distilled water.
Warranty and coverage
The Tudor TA456 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 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.

How to change the battery
Step-by-step guide to replace your car battery in 15-30 minutes (longer if the battery is under the seat or in the boot) without losing vehicle settings.
Step 1. Prepare the vehicle
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Step 2. Locate the battery
Open the bonnet. The battery is usually in the engine bay, but in many modern cars it may be in the boot or under the passenger seat. Check the manual if you cannot find it.
Step 3. Disconnect the negative (−) terminal
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery
Loosen the bottom hold-down clamp with the same wrench. Lift the battery carefully (it can weigh 15-25 kg). Clean the tray with a brush and baking soda if there is corrosion.
Step 6. Install the new battery
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Step 7. Connect the cables
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Step 8. Verify the engine starts
Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.
Frequently asked questions
How is the Tudor TA456 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 TA456 model?
Expected lifespan of the Tudor TA456 is 4 to 6 years in regular car 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 TA456 battery?
Dimensions (length × width × height) are 237×127×227 mm — also written as 237x127x227 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.
Does this battery fit my car?
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 TA456 typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the TA456 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 — 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.
