Replacing BMW 3 Series Battery

Model: BMW Serie 3 E91, E90, E92 - Years 2005-2013
Part: Battery

Open the trunk and empty it to work more easily. To your right, looking inside the trunk, you will notice a small panel with a sort of screw that you can unscrew by hand. Once done, unscrew the two 10 mm bolts (this time with a power tool or wrench) that hold the black plastic retainer, as shown in the video. Then unscrew the 10 mm bolts at the negative terminal (first) and positive terminal (next). Remove the battery cover by disconnecting the connectors secured with clips. Using a plastic pry tool, lift the battery out of its seat and finally, remove it.
