What are the dimensions: thickness and diameter.? not package dimensions (useless information).

Hi, cable is 4.5cm. Battery dims are 12.5mm in diameter and 2mm in height.

Do the metal pins go up or down and are you supposed to hold on button while installing

I installed my CMOS on a Dell XPS-15 Model 9570. CONDUCT YOUR RESEARCH VIA GOOGLE SEARCH! Some very-explicit instructional monologues and YouTube videos, which I did access, for my removal and installation. You do know, you must-LITERALLY-disassemble the entire computer. AND YOU MUST HAVE ON HAND, FOR REASSEMBLY, 1) high-quality grease, to reattach the heat sink, to the CPU, and, 2) a good, safe solvent, as 91% isopropyl alcohol, to COMPLETELY remove the old grease, and, 3)some super-fine grit sandpaper or emory cloth, to remove old grease residue, AND POLISH THE HEAT SINK AND CPU CONTACT SURFACES, TO A MIRROR FINISH---NO JOKE! And it is only a grease, not a glue or adhesive, you will remove, and reapply. Male plug only inserts into female receptacle one way, as a security feature, to prevent reverse-polarity mistake. There is no physical reset "button" to actuate; you must reset the Real Time Clock (RTC) via settings---easy task for the RTC set. AGAIN, FIND YOUR MONOLOGUES AND VIDEOS.

Will this work for a XPS 9550?
