CMOS Battery for Dell Latitude E5440 E5450 E6440 E6420 E7440 E7240,CMOS battery for Dell AlienWare M11x R1 R2 Area-51 M9700 M9750 laptop BIOS RTC CR2032 Battery with 2 Wire Cable and connector.

After some research this looked like it would work with a Intel nuc 9 extreme compute element and it did.

This battery fit perfectly. Dell changed the connector in the later models slightly and reversed the polarity, so I was thankful this one matched the battery i was replacing exactly. Thanks you for the accurate descriptions of which models this battery applied to.

Fit perfectly in my dell laptop with easy plug and play installation!

Fit perfectly and arrived on time. Would purchase again if needed.

Arrived quickly and seems to be working well!

Revives Old Dell Laptops with a Simple FixThis little CMOS battery turned out to be exactly what my older Dell Latitude needed. My laptop had started giving the dreaded "time/date not set" message at every startup and sometimes struggled to get past the BIOS screen. Swapping in this replacement solved the issue right away—boot times are normal again, and no more BIOS clock resets.The battery came pre-wired with the right two-pin connector, which made installation straightforward. On my Latitude E7440, it was just a matter of opening the back cover, locating the old CMOS battery, and plugging this one in. The fit was snug and secure, no soldering required.A couple of things to keep in mind: this is not a universal fit for all laptops—it’s wired specifically for certain Dell models. Be sure to double-check compatibility before ordering. Also, while the battery cable is long enough for the Dells I’ve worked on, the wire is fairly thin, so take care not to tug too hard during installation.Bottom line: If you’ve got an aging Dell Latitude or Alienware throwing BIOS errors, this affordable CMOS replacement can breathe new life into it without a trip to the repair shop.

Plugged right into my laptop’s, motherboard and works great
