Why would a 2007 BMW 335i battery with good charge but have no power?

A 2007 BMW 335i battery with a good charge but no power could indicate a few issues. It may be caused by a faulty connection or corroded battery terminals that prevent power from reaching the electrical system. Alternatively, a malfunctioning alternator or blown fuses could also disrupt power distribution, even if the battery itself is charged. Lastly, issues with the vehicle's ignition system or wiring could prevent the car from starting or functioning properly.
