ESA Battery Replacement

A sticker on the back of my E4402B says the life expectancy of the “processor battery” is 7 years and my unit is now 8 years old.  Looking under the hood, the only battery I can find is a “snaphat” atop the timekeeper chip.  Anyone know if that’s it or is there another “keep alive” battery still lurking elsewhere?
