2017 BMW 750i Auxiliary Battery Location
In the 2017 BMW 750i, the auxiliary battery is typically mounted in the front-left engine bay compartment, adjacent to the main battery but isolated to prevent electrical interference. It is secured with a rubber strap and connected via a dedicated wiring harness for critical systems like lights, infotainment, and climate controls. Access requires removing a protective panel behind the spare tire cover or engine cover, depending on trim, ensuring safe handling and clear identification.
Why Knowing the Location Matters
Accurate knowledge of the auxiliary battery’s position supports timely diagnostics and prevents accidental damage during maintenance. Technicians and owners alike rely on this information to jump-start auxiliary systems or replace faulty units without disrupting main power functions.

When servicing, use a battery terminal wrench and insulated tools; always disconnect the auxiliary battery last during disassembly to avoid short circuits. Refer to the owner’s manual for exact diagrams specific to your 2017 model year.
