Introduction
Go to step 1 ↓It is important to note that removing the memory battery will cause the camera to forget all of your settings. It would be helpful to document your settings before performing these steps. Perform these steps as basic troubleshooting, much like a soft reset.

This Battery for Clock only? or CMos and Personal setting to?
there has to be something to retain all these settings once the main battery pack goes dead and or is removed from the camera?
My User 1 Pictures styles wont Save? it'll save but once i turn off My Canon Eos 5D Mark II and then back on again, my Color /Contrast/Sharpness are all Dead Center/= back to Default AGAIN? :/
Any Help here?
THANK YOU,
I did not write the original post, but I believe once you remove this battery ALL custom changes and time will be gone. You will have to re-create them. Besides the rechargeable battery, the only one keeping track of some settings is this one.

Will doing this reset the shutter count in the camera? Like when you go to an external program to see how many shutter actuations there have been over the lifetime of the camera, will that number be erased?
No, because some faulty behavior i removed my clock battery from my 5D MK2, but the shutter count is still the same, it would be to easy to hack a camera to be sold on a good price. :)
