Nope. CMOS memory is either a standalone NVRAM ic or is contained inside SMC (system management controller), it acts similar to system RAM (needs power to maintain memory). The one you link is a BIOS ROM, it does not need power to maintain its content. I believe I wrote it up higher in this thread. It is usually located close to the battery plug but can be anywhere the manufacturer found some room to place it.
Test booting up without the battery - it should load up BIOS defaults every time.
Edit: I do not think the LGA 1150 board is worth the labor in this case.
