680*A* Cold cranking
17.90*kg* Weight

Designed for cars with Start-Stop, regenerative braking and heavy electrical loads, the **Tudor TK620** from the **AGM Microhybrid** range combines **62 Ah** and **680 A** of cold cranking current (EN) with AGM construction able to withstand hundreds of starts a day. It replaces the original battery without adaptation in Start-Stop cars with a 242 × 175 × 190 mm format: same 62 Ah capacity and the positive terminal on the right.
- Compatible with regenerative braking and energy management (BMS).
- Up to three times the cycles of a conventional battery.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Withstands hundreds of starts a day without degrading.

### Vehicles compatible with the Tudor TK620

According to our database, the Tudor TK620 equips more than 539 vehicles from brands such as Citroën, Mercedes-Benz, Fiat, Hyundai, Volkswagen and BMW, among others. For anyone who needs to replace the **battery in their Citroën** or Mercedes-Benz, this Tudor TK620 reproduces the original specifications. Models from Kia, Volvo, Peugeot, Renault, Nissan, Seat, Toyota and Audi are added to that list. It is checked against 230 original-equipment references from different manufacturers.

### Size, terminals and hold-down of the Tudor TK620

The Tudor TK620 is made in the 242 × 175 × 190 mm format and weighs 17.90 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 B13 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### The Tudor TK620: AGM Microhybrid range and AGM technology

Within the Tudor catalogue, the **AGM Microhybrid** series groups the references designed for this use. The TK620 is the 62 Ah model of that family, with the same performance as its siblings in other sizes.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

### What Tudor does differently

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 TK620 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.

### Usage and maintenance tips

Do not mix technologies: a conventional battery in a Start-Stop car degrades within months. If the vehicle only does very short trips, a periodic maintenance charge with an AGM/EFB-compatible charger greatly extends its life.

### 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.

## Frequently asked questions

### Is the TK620 model AGM? What does this technology offer?

Yes. The TK620 from Tudor uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for cars with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.

### Is this battery compatible with Start-Stop systems?

Yes. As AGM technology it is designed for Start-Stop vehicles. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. EFB is recommended for basic Start-Stop; AGM is recommended when regenerative braking is also present, thanks to its higher cycle capability. It works straight out of the box — on most modern vehicles registering the battery via OBD is recommended so the alternator automatically applies the optimal charging profile.

### How do I fit the TK620 model in my car?

In most cars 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 our blog. 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 — with positive on the right match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Tudor TK620 battery last?

Expected lifespan of the Tudor TK620 is 5 to 8 years in mild-climate car use with 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 measurements of the TK620 model?

Dimensions (length × width × height) are 242×175×190 mm — also written as 242x175x190 mm and correspond to the European L2 case size — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### What polarity does the Tudor TK620 battery have?

Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Will the Tudor TK620 battery fit my car?

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 TK620 fits 556 verified vehicle versions in our database.

### Which batteries are equivalent to the Tudor TK620?

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 cars. See the "Equivalents" section to view recommended options at the same performance level.

### What advantages does the Tudor TK620 AGM battery offer over an EFB?

AGM (Absorbent Glass Mat) technology uses absorbent fibreglass that retains the electrolyte, eliminating leaks and allowing up to 3× more charge/discharge cycles than a conventional battery. It is the recommended option when the car has advanced Start-Stop with regenerative braking (BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO, Volvo i-Stop). Withstands tilted positions, high vibration and extreme temperatures better than EFB. The Tudor TK620 is fully original and meets European EN 50342-6 standards for advanced Start-Stop.

### Do I need to register the Tudor TK620 on the car after installation?

On most cars it is not strictly necessary — the alternator detects the new battery and adapts the charge automatically. It is recommended to register the battery via OBD so that the alternator applies the optimal charging profile from the first minute and extends the battery life as much as possible (especially on brands with sophisticated BMS: BMW, Mercedes, Audi, Volvo, Land Rover). Any workshop with an OBD scanner (~10-15 € labour) does it in 5 minutes. DIY apps: VCDS / Carista (VAG), Bimmercode (BMW), iCarsoft. If you do not register, the car will still start correctly — the alternator just takes a few days to adjust the profile. The Tudor TK620 ships factory-charged at 80-90% so you can use it straight after fitting.
