Car battery Tudor TB451 Technica 45Ah 330A 12V
The Tudor TB451 car battery is rated at 12 V, 45 Ah and 330 A of cold cranking current (EN) from the Technica range, and is designed for passenger cars with conventional starting, without a Start-Stop system. It replaces the original battery without adaptation in cars with a 220 × 135 × 225 mm format: same 45 Ah capacity and the positive terminal on the left.
In short: the Tudor TB451 (45 Ah, 330 A, 220 × 135 × 225 mm, positive terminal on the left). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size. Verified equivalent alternatives: Varta B24 and Exide EB451.
- 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.
Vehicles compatible with the Tudor TB451
The Tudor TB451 is compatible with more than 20 vehicles: it is fitted as original equipment or as a replacement by brands such as Morgan, Talbot, Austin, Reliant, Hyundai and Rover. If you are looking for a battery for a Morgan or Talbot with these dimensions, the TB451 is one of the usual replacement references. The compatibility list also includes models from Morris and Bedford. It covers 17 original-equipment references, one of the widest coverages in its format.
The Tudor TB451: Technica range and conventional lead-acid technology
The TB451 is part of the Tudor Technica range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.
Dimensions, polarity and mounting
It has external dimensions of 220 × 135 × 225 mm and weighs 11.90 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
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. We guarantee that every Tudor arrives new, charged and with the manufacturer's full warranty.
Usage and maintenance tips
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.
Warranty and coverage
The Tudor TB451 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.

Frequently asked questions
How is the Tudor TB451 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 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 (−) 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 — with positive on the left 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.
How long does the Tudor TB451 battery last?
Expected lifespan of the Tudor TB451 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 TB451 battery?
Dimensions (length × width × height) are 220×135×225 mm — also written as 220x135x225 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.
What polarity does the Tudor TB451 battery have?
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 TB451 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 TB451 fits 34 verified vehicle versions in our database.
Which batteries are equivalent to the Tudor TB451?
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.
