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.
- 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.
Delivery times and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

How to change the battery
Guide to replace a truck battery in 30-60 minutes. Truck batteries weigh 25-50 kg — we recommend working in pairs and using a carrying strap.
Step 1. Prepare the vehicle
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Step 2. Locate the battery
Open the bonnet. The battery is usually in the engine bay, but in many modern cars it may be in the boot or under the passenger seat. Check the manual if you cannot find it.
Step 3. Disconnect the negative (−) terminal
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery (two people)
Loosen the bottom hold-down clamp. Truck batteries weigh 25-50 kg — lift in pairs with gloves and a carrying strap. Forcing the lift alone risks back injury.
Step 6. Install the new battery
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Step 7. Connect the cables
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Step 8. Verify the engine starts
Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.
Frequently asked questions
How do I change this battery step by step?
In most trucks it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Tudor TF1250 battery last?
Expected lifespan of the Tudor TF1250 is 4 to 7 years in regular use (depends on technology and climate). In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the Tudor TF1250 battery?
Dimensions (length × width × height) are 349×175×285 mm — also written as 349x175x285 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Is the TF1250 valid for my vehicle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The TF1250 typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the TF1250 model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop trucks. See the "Equivalents" section to view recommended options at the same performance level.
