Car battery Tudor TB504 Technica 50Ah 360A 12V

The Tudor TB504 from the Technica range delivers 50 Ah and 360 A of cold cranking current (EN) at 12 V: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It measures 200 × 173 × 222 mm and the positive terminal on the right, the format sought by anyone replacing a 50 Ah battery in cars.

In short: the Tudor TB504 (50 Ah, 360 A, 200 × 173 × 222 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.

• Original-equipment build quality without the dealership price.
• Direct replacement for the original battery in size and terminals.
• Reliable cold starts, even after weeks without driving.
• Conventional lead-acid: the most proven and economical technology.

What the Tudor TB504 is for

The Tudor TB504 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.

Will it fit your current battery tray?

In terms of format, the Tudor TB504 measures 200 × 173 × 222 mm (length × width × height) and weighs 13 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.

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. We guarantee that every Tudor arrives new, charged and with the manufacturer's full warranty.

The Tudor TB504: Technica range and conventional lead-acid technology

Within the Tudor catalogue, the Technica series groups the references designed for this use. The TB504 is the 50 Ah model of that family, with the same performance as its siblings in other sizes.

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.

Usage and maintenance tips

Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Warranty and coverage

The Tudor TB504 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.
