Car battery Tudor TB442 Technica 44Ah 420A 12V

With 44 Ah at 12 V and 420 A of cold cranking current (EN), the Tudor TB442 from the Technica range is a starter battery built for passenger cars with conventional starting, without a Start-Stop system. Measuring 207 × 175 × 175 mm and the positive terminal on the right, it is the direct replacement for cars fitted from the factory with a 44 Ah battery of this format.

In short: the Tudor TB442 (44 Ah, 420 A, 207 × 175 × 175 mm, positive terminal on the right). 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 B18 and Exide EB442.

• 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 TB442

This battery appears as compatible in more than 290 vehicles from manufacturers such as Ford, Renault, Opel, Vauxhall, Nissan and Westfield. For anyone who needs to replace the battery in their Ford or Renault, this Tudor TB442 reproduces the original specifications. Models from Volkswagen, Suzuki, Lotus, Rover, Chevrolet, Seat, Fiat and Citroën are added to that list. It is checked against 102 original-equipment references from different manufacturers.

Dimensions, polarity and mounting

It has external dimensions of 207 × 175 × 175 mm and weighs 10.60 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 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. All the Tudor batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Tudor TB442: Technica range and conventional lead-acid technology

The Technica is the Tudor range the TB442 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.

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.

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. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Official warranty

The Tudor TB442 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.
