Worked as Expected for Dell XPS
Purchased as a replacement for the factory CMOS battery in my Dell XPS 13 9370. It has worked as expected since I installed it two months ago. My only complaint is that the wiring harness is slightly long, but that varies upon your laptop.

Worked perfectly
Cable is not as long as it looks in the picture, but still longer than the original battery cable. Replaced it without issue and comes with adhesive like the original battery.

Does exactly what it is supposed to
I used this to replace the CMOS battery on a 2018 Dell XPS 13 9365 All-in-One folding laptop. The cable is slightly longer than the OEM, but this was not really an issue. The replacement was very easy.

Cable lead is a bit longer than OEM
Works as intended as a replacement for the dead cmos I have on my 9560 XPS 15. However the cable is a bit longer than the OEM cable so you might need to get creative with cable management inside the laptop to make it fit.

An Odd but Necessary Item
If you don't know what a CMOS battery is, that's because you've been fortunate to have not needed on yet. If you do need a CMOS, you know that the web is full of pages to change yours. Generally speaking, changing this battery is not hard and most people can handle one. This one makes it super easy because of its quality and design. I highly recommend.
