In short: the Tudor TB455 (45 Ah, 330 A, 237 × 127 × 227 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 B34 and Exide EB455.

• 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.

What the Tudor TB455 is for

Designed for passenger cars with conventional starting, without a Start-Stop system, the Tudor TB455 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 11.40 kg.

Will it fit your current battery tray?

The Tudor TB455 is made in the 237 × 127 × 227 mm format and weighs 11.40 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. 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.

The Tudor TB455: Technica range and conventional lead-acid technology

The Technica is the Tudor range the TB455 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.

The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

What Tudor does differently

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. 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 TB455 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.

Usage and maintenance tips

In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. 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.
