# EXIDE AGM > Exide AGM batteries for Start-Stop cars with regenerative braking: 60-105 Ah, 680-950 A. EK600 to EK1050 with Dispatched within 24h, 14-day returns. **Category:** [Start](https://baterias.com/gb/) → [Battery brands](https://baterias.com/gb/battery-brands) → [EXIDE batteries](https://baterias.com/gb/batteries-exide) - **Canonical URL**: https://baterias.com/gb/exide-agm - **Language**: en-GB ## Description **Exide AGM batteries** in the EK series are Exide's top range for cars with **regenerative-braking Start-Stop**: sealed, maintenance-free AGM (Absorbent Glass Mat) technology from 60 to 105 Ah with 680 to 950 A of cranking power (CCA). It is the direct counterpart of Tudor AGM Microhybrid and Varta Dynamic AGM. If you need an **Exide battery for a Start-Stop car** with high electrical demand — BMW, Mercedes, Audi and large SUVs that recover energy while braking — this series replaces the factory-fitted AGM with the same technology and cranking power. ## Exide AGM: power and cycle life for demanding Start-Stop cars In an **AGM battery** the electrolyte is absorbed in glass-mat separators: the battery is fully sealed, maintenance-free and accepts fast charging, so it can store the energy recovered under **regenerative braking** and withstand far more start cycles than a conventional battery. That is why cars with advanced Start-Stop and heavy electrical equipment are fitted with AGM at the factory — and why it must only be replaced with another AGM. ### Models in the Exide EK series - **Exide EK600** — 60 Ah, 680 A: compact AGM for superminis and hatchbacks with Start-Stop. - **Exide EK700** — 70 Ah, 760 A: D-segment saloons with regenerative braking. - **Exide EK800** — 80 Ah, 800 A: premium SUVs with high electrical demand. - **Exide EK920** — 92 Ah, 850 A: large premium saloons and SUVs. - **Exide EK1050** — 105 Ah, 950 A: Porsche Cayenne, Range Rover and similar 4x4s. ### How to choose a compatible Exide AGM battery Replace like for like: same technology, equal or higher capacity than the original. Enter your vehicle in our [battery comparator](https://baterias.com/gb/comparator) or find it instantly with the [battery finder by number plate](https://baterias.com/gb/battery-finder-by-plate) to see only the Exide AGM batteries that fit your car. On BMW, Mercedes, Audi and VAG-group cars the new battery must be coded via OBD after fitting. ## Frequently asked questions about Exide AGM batteries ### **What is the difference between an Exide AGM and an EFB battery?** AGM is designed for **Start-Stop with regenerative braking** and high electrical loads; EFB covers basic Start-Stop. An AGM can replace an EFB, but never the other way round: downgrading from AGM to EFB shortens battery life. ### **Which battery does my Start-Stop car take?** The same technology it left the factory with: check the label on the current battery (AGM or EFB) or enter your number plate in our finder and we will show you the exact Exide model. ### **Does the AGM battery need coding after replacement?** On BMW, Mercedes, Audi and VAG-group cars, yes: the new battery must be registered via OBD after fitting so the charging management works correctly. ### **Is an Exide AGM compatible with my original Varta or Tudor?** Yes, as long as case size, capacity and technology match: the Exide EK series is the direct counterpart of Tudor AGM Microhybrid and Varta Dynamic AGM.
