BMW battery information
Nearly every BMW built since 2008 uses an AGM or EFB battery that must be electronically registered to the vehicle's Intelligent Battery Sensor (IBS) after replacement. Skip the registration and the BMS keeps treating the new battery as if it were old — leading to disabled start-stop, gearbox warnings and premature failure within 18 months.
Our mobile technicians carry professional BMW coding tools (ISTA-compatible) and the full Varta Silver Dynamic AGM and Bosch S6 ranges. Every BMW battery we fit is registered to the IBS on the spot, with a printed confirmation of capacity, CCA, technology and registration date.
Battery types we fit for BMW
- AGM (Silver Dynamic / S6)
- EFB (Blue Dynamic)
- Standard SLI for pre-2008 models
