Changing the CMOS Battery

My many M50s (8189) are old enough that their CMOS batteries are dying. What is the correct way to change and then re-install the battery? The Hardware Maintenance Manual shows a different battery clip that these models have. The HMM shows a single clip to release; these units have a spring going all the way across the battery. The case block the battery on the edge away from the spring clip, the PCI connector blocks one side, and components block the other. A visual aid would be very much appreciated.
