- Low self-discharge: copes with long stops without losing charge.
- Designed to last several years under normal daily use.
- Good balance of capacity, cranking power and price.
- Stable voltage for the vehicle electronics (ECU, sensors, climate control).

### Vehicles compatible with the Tudor TB450

The Tudor TB450 is compatible with more than 33 vehicles: it is fitted as original equipment or as a replacement by brands such as Piaggio, Marcos, Renault, Hyundai, Nissan and Rover. For anyone who needs to replace the **battery in their Piaggio** or Marcos, this Tudor TB450 reproduces the original specifications. The compatibility list also includes models from Mazda and Suzuki. It is checked against 31 original-equipment references from different manufacturers.

### Dimensions, polarity and mounting

It has external dimensions of 220 × 135 × 225 mm and weighs 11.90 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. 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.

### 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 TB450: Technica range and conventional lead-acid technology

The **Technica** is the Tudor range the TB450 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.

### Care and maintenance

Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. 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.

### Warranty and coverage

The Tudor TB450 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.

### Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### How is the Tudor TB450 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 TB450 model?

Expected lifespan of the Tudor TB450 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 size is this 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.

### Is the TB450 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 TB450 fits 33 verified vehicle versions in our database.

### Which batteries are equivalent to the Tudor TB450?

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.
