The **Tudor TL800** with EFB technology delivers the **80 Ah** at **12 V** and **800 A** of cold cranking current (EN) that cars with Start-Stop, regenerative braking and heavy electrical loads need. Measuring 315 × 175 × 190 mm and the positive terminal on the right, it is the direct replacement for Start-Stop cars fitted from the factory with a 80 Ah battery of this format.
- EFB: the evolution of the conventional battery for basic Start-Stop cars.
- Fast recharge on the move thanks to low internal resistance.
- Keeps comfort loads running with the engine off at the lights.
- Direct replacement for the original Start-Stop battery.

### What the Tudor TL800 is for

In Start-Stop cars the battery works far harder than in a conventional car; the Tudor TL800 is built for that intensive cycling and to recharge quickly on the move. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 22.10 kg.

### The Tudor TL800: EFB Microhybrid range and EFB technology

The **EFB Microhybrid** is the Tudor range the TL800 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.
EFB (Enhanced Flooded Battery) technology reinforces the conventional lead-acid battery with a polyester separator and carbon additives in the plates. It withstands many more start cycles and partial discharges, making it ideal for basic Start-Stop and intensive use.

### Will it fit your current battery tray?

The Tudor TL800 is made in the 315 × 175 × 190 mm format and weighs 22.10 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.

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

### Care and maintenance

A charger with an EFB or smart conventional mode is enough; avoid the high-voltage modes intended for AGM. 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.

### Manufacturer's warranty

The Tudor TL800 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.

### Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### Is this battery EFB? When is it used?

Yes. The TL800 is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. Withstands more cycles than a conventional but fewer than an AGM. Fitted to cars with basic Start-Stop (no regenerative braking). More affordable than an equivalent AGM, lifespan 4-6 years.

### Is the Tudor TL800 battery suitable for Start-Stop?

Yes. As EFB technology it is designed for Start-Stop vehicles. EFB batteries cover basic Start-Stop (no regenerative braking). 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 is the Tudor TL800 battery installed in the vehicle?

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 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 cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Tudor TL800 battery last?

Expected lifespan of the Tudor TL800 is 4 to 6 years in basic Start-Stop car use. 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 TL800 battery?

Dimensions (length × width × height) are 315×175×190 mm — also written as 315x175x190 mm and correspond to the European L4 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.

### Is the TL800 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 TL800 fits 47 verified vehicle versions in our database.

### Which batteries are equivalent to the Tudor TL800?

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 exactly is an EFB battery like the Tudor TL800?

An EFB (Enhanced Flooded Battery) is a flooded lead-acid battery reinforced with plate additives (carbon and polyethylene) and thicker grids. It withstands twice the cycles of a conventional battery and handles deep discharges better, but less than an AGM. It is the original fitment on cars with basic Start-Stop (no regenerative braking): Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG, Ford EcoBoost. If your car came with EFB from the factory, this is the correct battery — upgrading to AGM is optional (marginal improvement). If it came with AGM, EFB may fall short: better fit AGM. The Tudor TL800 is original and meets EN 50342-6.

### Do I need to register the Tudor TL800 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 TL800 ships factory-charged at 80-90% so you can use it straight after fitting.
