How to Change a BMW M5 Car Battery


1. Open the trunk and lift up on the small, black-looped handle to pull up the luggage compartment carpet and floor.
2. Locate the battery compartment. The battery compartment is located near the right rear wheel.
3. Turn the lock nuts 1/4 turn to loosen and remove them. Then, pull up on the battery cover.
4. Loosen the retaining nuts on the battery brace and pull the brace off the top of the battery.
5. Loosen the retaining nut on the negative battery cable clamp and slide the negative battery cable clamp off the battery terminal.
6. Loosen the positive battery terminal cable clamp retaining nut with a socket wrench and slide the positive cable clamp off the battery terminal.
7. Lift the old battery out of the battery compartment and lower the new battery in.
8. Reconnect the battery cable clamps. Connect the positive clamp first, then connect the negative clamp last. You must connect the negative battery clamp last to avoid a sudden shock or arcing of the power terminal.
9. Put the battery cover back and secure it with the lock nuts, and then lower the luggage compartment floor and carpet.
