## Description

## Start-Stop battery Tudor TL550 EFB Microhybrid 55Ah 540A 12V

12*V* Voltage
55*Ah* Capacity
540*A* Cold cranking
14.10*kg* Weight

The **Tudor TL550** with EFB technology delivers the **55 Ah** at **12 V** and **540 A** of cold cranking current (EN) that cars with Start-Stop, regenerative braking and heavy electrical loads need. It replaces the original battery without adaptation in Start-Stop cars with a 207 × 175 × 190 mm format: same 55 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.
- EFB technology: reinforced electrolyte for many more start cycles.
- Withstands hundreds of starts a day without degrading.

### Will it fit your current battery tray?

In terms of format, the Tudor TL550 measures 207 × 175 × 190 mm (length × width × height) and weighs 14.10 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. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

### What the Tudor TL550 is for

The Tudor TL550 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 14.10 kg.

### The Tudor TL550: EFB Microhybrid range and EFB technology

Within the Tudor catalogue, the **EFB Microhybrid** series groups the references designed for this use. The TL550 is the 55 Ah model of that family, with the same performance as its siblings in other sizes.
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.

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

### Warranty and coverage

The Tudor TL550 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.

### Care and maintenance

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 [[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 the TL550 model EFB? Which cars need it?

Yes. The TL550 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 this battery compatible with Start-Stop systems?

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 do I fit the TL550 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 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 TL550 battery last?

Expected lifespan of the Tudor TL550 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 size is this battery?

Dimensions (length × width × height) are 207×175×190 mm — also written as 207x175x190 mm and correspond to the European L1 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.

### Will the Tudor TL550 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 TL550 fits 91 verified vehicle versions in our database.

### Which batteries are equivalent to the Tudor TL550?

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.

### When is EFB fitted instead of AGM?

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 TL550 is original and meets EN 50342-6.

### Will my car recognise the new battery automatically?

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 TL550 ships factory-charged at 80-90% so you can use it straight after fitting.
