Designed for the auxiliary network of cars with advanced Start-Stop and heavy electronics, the **Exide EK013** stabilises the voltage with **1.2 Ah** with AGM technology. Its 97 × 43 × 58 mm and the positive terminal on the right make it the exact replacement for the 1.2 Ah battery fitted as standard to many vehicles with an auxiliary battery.
- Protects the main battery and the alternator.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Direct replacement for the original auxiliary battery.
- Supports advanced Start-Stop systems.

### Vehicles compatible with the Exide EK013

The Exide EK013 is compatible with more than 14 vehicles: it is fitted as original equipment or as a replacement by brands such as Mercedes-Benz. If you are looking for a **battery for a Mercedes-Benz** with these dimensions, the EK013 is one of the usual replacement references. It is checked against 3 original-equipment references from different manufacturers.

### Dimensions, polarity and mounting

In terms of format, the Exide EK013 measures 97 × 43 × 58 mm (length × width × height) and weighs 0.50 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 B00 hold-down and Faston S (4,8) terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

### What Exide does differently

With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty.

### Technology inside the Exide EK013

The EK013 is one of the Exide references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.
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.

### Care and maintenance

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. The auxiliary battery works alongside the main one: if a support-network fault warning appears, check both.

### Warranty and coverage

The Exide EK013 comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.

### When you get it and how to return it

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 EK013 model AGM? What does this technology offer?

Yes. The EK013 from Exide 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 the Exide EK013 battery suitable for Start-Stop?

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 EK013 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 Exide EK013 battery last?

Expected lifespan of the Exide EK013 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 EK013 model?

Dimensions (length × width × height) are 97×43×58 mm — also written as 97x43x58 mm — 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 EK013 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 EK013 fits 14 verified vehicle versions in our database.

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

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 Exide EK013 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 Exide EK013 is fully original and meets European EN 50342-6 standards for advanced Start-Stop.

### 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 Exide EK013 ships factory-charged at 80-90% so you can use it straight after fitting.
