Tudor TG1250 · Truck battery 12V 125Ah 760A

Truck battery Tudor TG1250 Start PRO (Hd) 125Ah 760A 12V

The Tudor TG1250 with conventional lead-acid technology delivers 125 Ah at 12 V and 760 A of cold cranking current (EN): what trucks, buses, tractors and heavy machinery demand. 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 TG1250 (125 Ah, 760 A, 349 × 175 × 285 mm, positive terminal on the right). Verified equivalent alternatives: Varta J1 and Exide EG1250.

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

What the Tudor TG1250 is for

Designed for trucks, buses, tractors and heavy machinery, the Tudor TG1250 withstands constant chassis vibration and discharges during stops with active loads. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 29.50 kg, EN taper post terminals and B0 hold-down.

The Tudor TG1250: Start PRO (Hd) range and conventional lead-acid technology

The Start PRO (Hd) is the Tudor range the TG1250 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.

Dimensions, polarity and mounting

The Tudor TG1250 is made in the 349 × 175 × 285 mm format and weighs 29.50 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 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.

Care and maintenance

During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Warranty and coverage

The Tudor TG1250 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.

Delivery times and returns

Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.
