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.

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.
