## Questions & Answers

**Q: What are the dimensions: thickness and diameter.?  not package dimensions (useless information).**
A: Hi, cable is 4.5cm. Battery dims are 12.5mm in diameter and 2mm in height.

**Q: Do the metal pins go up or down and are you supposed to hold on button while installing**
A: 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.

**Q: Will this work for a XPS 9550?**
A: Hello,

Yes, this RTC CMOS battery work,

**Q: Will this work in an XPS 15 9530?**
A: Yes, it worked fine in mine.
