Car battery Tudor TB505 Technica 50Ah 360A 12V

The Tudor TB505 car battery is rated at 12 V, 50 Ah and 360 A of cold cranking current (EN) from the Technica range, and is designed for passenger cars with conventional starting, without a Start-Stop system. Its 200 × 173 × 222 mm and the positive terminal on the left make it the exact replacement for the 50 Ah battery fitted as standard to many cars.

In short: the Tudor TB505 (50 Ah, 360 A, 200 × 173 × 222 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.

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

What the Tudor TB505 is for

The Tudor TB505 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 13 kg.

Dimensions, polarity and mounting

In terms of format, the Tudor TB505 measures 200 × 173 × 222 mm (length × width × height) and weighs 13 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. 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 TB505: Technica range and conventional lead-acid technology

The TB505 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.

How to make it last longer

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

Official warranty

The Tudor TB505 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.
