### ⭐⭐⭐⭐⭐ Worked as Expected for Dell XPS
*by S***E on September 30, 2020*

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
*by A***R on November 12, 2021*

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
*by B***A on January 19, 2025*

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.
