The Tudor TG145A truck battery is rated at 12 V, 145 Ah and 1,000 A of cold cranking current (EN) from the Start PRO (Hd) range, and is prepared for trucks, buses, tractors and heavy machinery. Its 360 × 253 × 240 mm make it the exact replacement for the 145 Ah battery fitted as standard to many trucks.
- Resistant to constant chassis vibration.
- Good balance of capacity, cranking power and price.
- Better tolerance to deep discharge than a conventional starter battery.
- Powers tachograph, fridge and heater during rest stops.
What the Tudor TG145A is for
The Tudor TG145A is designed for trucks, buses, tractors and heavy machinery. In 24 V installations with two batteries in series, replace both at the same time to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 38.10 kg.
Dimensions, polarity and mounting
The Tudor TG145A is made in the 360 × 253 × 240 mm format and weighs 38.10 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
Tudor: the maker behind the TG145A
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 TG145A: Start PRO (Hd) range and conventional lead-acid technology
The TG145A is part of the Tudor Start PRO (Hd) range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.
How to make it last longer
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.
Official warranty
The Tudor TG145A 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
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

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 is the Tudor TG145A battery installed in the vehicle?
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 many years does this battery last?
Expected lifespan of the Tudor TG145A is 4 to 6 years in regular truck use without Start-Stop. 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 TG145A battery?
Dimensions (length × width × height) are 360×253×240 mm — also written as 360x253x240 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 TG145A 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 TG145A typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the TG145A 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.
