If you drive a modern European vehicle, your battery is doing a lot more than just starting the engine. At Battery Brands Warehouse, we specialize in the high-performance AGM and Auxiliary batteries required by Mercedes, Audi, BMW, and Volkswagen.
What is an AGM Battery?
Modern Euro cars use Absorbent Glass Mat (AGM) technology. These batteries are designed to handle the heavy electrical loads of Start-Stop systems and regenerative braking. A standard battery will often fail within months if installed in a car designed for AGM.

The "Secret" Second Battery: Auxiliary Supply & Fit
Most modern Mercedes and BMWs use a dual-battery system. While the main battery handles the heavy lifting, a smaller Auxiliary battery runs your onboard computers, safety systems, and interior electronics. At Battery Brands Warehouse, we stock and fit a full range of Auxiliary batteries to get rid of those "Battery Malfunction" dash lights instantly.
Safe Installation: OBD Scanning & Memory Savers
European cars are "computers on wheels." We take the risk out of battery replacement by using specialized equipment for every fitment:
- OBD Memory Savers: We keep your vehicle powered during the swap so you don't lose your radio codes, seat positions, or clock settings.
- Battery Registration: Many modern BMW, Audi, and Mercedes models require the new battery to be "registered" with the ECU. We provide the scanning and reset services needed to ensure your alternator charges the new battery at the correct rate.
Professional Fit – No Booking Required
We are experts at European installations, including batteries hidden in the rear boot or under the front seats.
- Fast Service: Most installations are completed in 30–45 minutes.
- Walk-ins Welcome: In most cases, no booking is required!
- Expert Advice: For complex under-seat or rear-boot fits, we recommend a quick call ahead to ensure a specialist bay is ready for you.
