950*A* Cold cranking
29*kg* Weight

The **Tudor TK1050** with AGM technology delivers the **106 Ah** at **12 V** and **950 A** of cold cranking current (EN) that cars with Start-Stop, regenerative braking and heavy electrical loads need. It measures 392 × 175 × 190 mm and the positive terminal on the right, the format sought by anyone replacing a 106 Ah battery in Start-Stop cars.
- Up to three times the cycles of a conventional battery.
- Compatible with regenerative braking and energy management (BMS).
- Withstands hundreds of starts a day without degrading.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.

### What the Tudor TK1050 is for

The Tudor TK1050 is designed for cars with Start-Stop, regenerative braking and heavy electrical loads. If your car was fitted with an AGM or EFB battery, always replace it with the same technology: a conventional model would degrade within months. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 29 kg.

### The Tudor TK1050: AGM Microhybrid range and AGM technology

The **AGM Microhybrid** is the Tudor range the TK1050 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.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

### Dimensions, polarity and mounting

The Tudor TK1050 is made in the 392 × 175 × 190 mm format and weighs 29 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### Why choose Tudor batteries

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### How to make it last longer

In a Start-Stop car the battery is controlled by the ECU; after replacing it, the new battery may need to be registered so the system adjusts charging. If the vehicle only does very short trips, a periodic maintenance charge with an AGM/EFB-compatible charger greatly extends its life.

### Manufacturer's warranty

The Tudor TK1050 comes with the **manufacturer's official warranty**. To keep it valid, always fit the same technology as the original battery (AGM or EFB) and register the replacement if your vehicle requires it.

### Shipping, delivery 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.

## Frequently asked questions

### Is the Tudor TK1060 an AGM battery and what are the benefits of AGM?

Yes. AGM (Absorbent Glass Mat) technology, 106 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance. It is also required in cars with advanced Start-Stop and regenerative braking.

### Is the TK1060 model suitable for Start-Stop cars?

AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. The Tudor TK1060 is AGM, so yes, it is designed for Start-Stop cars. Basic Start-Stop: EFB. Start-Stop with regenerative braking: AGM, which withstands more cycles. Check the handbook for the technology the car manufacturer requires. It works once fitted; on most modern cars, registering it via OBD is advisable so the alternator applies the optimum charging profile.

### How is the Tudor TK1060 battery fitted in a Start-Stop car?

On cars with Start-Stop or BMS, registering the battery via OBD makes the alternator charge with the correct profile. Mind the IBS sensor on the negative terminal too: loosen the cable nut, not the sensor. And the replacement must be the same technology (AGM or EFB) or higher: a conventional battery fails within months. Tool: a 10 mm spanner. Time: 15-30 minutes on almost every car, and up to double if the battery is not under the bonnet but in the boot or under a seat. Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way (positive on the right) to match the polarity; 6) connect the positive (+) and finally the negative (−). Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog.

### How long does the Tudor TK1060 battery last?

As a rough estimate, the Tudor TK1060 typically lasts 5 to 8 years in mild-climate car use with Start-Stop; it is a guide figure, not a guaranteed period. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance; the type of car and Start-Stop also count.

### What are the measurements of the TK1060 model?

It measures 392×175×190 mm in length × width × height, with the terminals included in the height; that is the European L6 case size. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close.

### Which side is the positive terminal on this battery?

Polarity of the Tudor TK1060: positive on the right. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit.

### Is the TK1060 valid for my vehicle?

The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). In every case, the car manufacturer's specifications (owner's handbook) take precedence. The TK1060 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which interchangeable batteries are there for this one?

Technology matters too: in Start-Stop cars, an EFB cannot be replaced with a conventional battery. The options at the same level are in the "Equivalents" section of this page. To replace the Tudor TK1060 without modifications, the other battery must be identical in size (L6 case), polarity, Ah and CCA.

### Tudor TK1050 or Varta LA105: which one to choose?

It is the verified Varta equivalent for the TK1050 tray. Compared with the TK1050 it has 1 Ah less. It costs 33,60 € more. Decide by price, brand preference and availability: both fit and crank the same.

### When do I need an AGM battery like this one?

Hence it is recommended for advanced Start-Stop with regenerative braking, such as BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO or Volvo i-Stop, and it handles tilting, vibration and extreme temperatures better than an EFB. AGM means Absorbent Glass Mat: the electrolyte soaks a glass-fibre mat (no spills), and an AGM battery lasts many more cycles than a conventional one. This TK1060 delivers 950 A cold cranking (EN).

### Is there anything to do after replacing a Start-Stop battery?

The alternator detects the new battery and adapts the charge automatically, so on most cars it is not compulsory. Even so, it is advisable to register it via OBD so charging is optimum from the first minute and the battery lasts longer, particularly on BMW, Mercedes, Audi, Volvo or Land Rover, with more sophisticated BMS. Any workshop with an OBD scanner does it in a few minutes; DIY, with VCDS or Carista (VAG group), Bimmercode (BMW) or iCarsoft. If you do not register the TK1060, it will keep starting fine while the alternator adjusts the profile over a few days.
