Truck battery Tudor TF1250 PRO (Hdx) 125Ah 850A 12V

With 125 Ah and 850 A of cold cranking current (EN), the Tudor TF1250 from the PRO (Hdx) range is built for professional use in trucks, buses, tractors and heavy machinery. Measuring 349 × 175 × 285 mm and the positive terminal on the right, it is the direct replacement for trucks fitted from the factory with a 125 Ah battery of this format.

In short: the Tudor TF1250 (125 Ah, 850 A, 349 × 175 × 285 mm, positive terminal on the right). Verified equivalent alternatives: Varta J1 and Exide EG1250.

• Powers tachograph, fridge and heater during rest stops.
• Better tolerance to deep discharge than a conventional starter battery.
• Good balance of capacity, cranking power and price.
• Resistant to constant chassis vibration.

Will it fit your current battery tray?

It has external dimensions of 349 × 175 × 285 mm and weighs 31 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. It uses a B0 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. 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.

What the Tudor TF1250 is for

With 125 Ah, the Tudor TF1250 cranks large-displacement diesel engines in the cold and powers tachograph, fridge and heater during rest stops. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31 kg, EN taper post terminals and B0 hold-down.

The Tudor TF1250: PRO (Hdx) range and conventional lead-acid technology

Within the Tudor catalogue, the PRO (Hdx) series groups the references designed for this use. The TF1250 is the 125 Ah model of that family, with the same performance as its siblings in other sizes.

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.

Tudor: the maker behind the TF1250

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.

Manufacturer's warranty

The Tudor TF1250 comes with the manufacturer's official warranty against manufacturing defects. An important note for commercial vehicles: most trucks use two batteries connected in series (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace both at the same time.

Usage and maintenance tips

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. On batteries with filler caps, check the electrolyte level and top up only with distilled water.
