EEMB 10-Pack CMOS Battery CR2032 3V Lithium Battery with 2 Pin 2 Wire Cable and MOLEX Connector CMOS Replacement for Alienware M11 Dell E6520 Thinkpad T40 Motherboards

Worked for what I needed. Replaced CMOS battery

After if did my first NUC I got drafted into fixing a number of them. This is a pack of 10 NUC specific CMOS batteries that just as promised tested over 3.35 volts. All the connectors were correct with reverse polarity and fit perfectly. If you’re getting a lot of crazy messages from your NUC it’s probably the CMOS battery. There’s no way to check the battery charge other than to open the machine up and get your meter out. The good news is that if you can figure out how to get to the CMOS battery in a NUC6CAYH (there's a great you tube that will walk you through this painful process)these batteries work great. You have to be careful because on a NUC the polarity on the CMOS battery connector is reversed so make sure you order the correct version. The batteries got here quickly and were charged over 3.35 volts so they should last for another 5 years. Great deal that got my NUC up and running again after I finally figured out how to get to the battery.

Tested all 10 batteries , and each were exactly 3.34v which is excellent, implying that they were likely manufactured recently.

We'll see if these last but they include the adhesive pad and have a generous pig tail (as advertised). The connector fit my Dell laptop perfectly.

these replacement costs batteries worked perfectly for my laptops.

These are well made and work very well. These are polarized for Intel Nucs and that's what I got them for. I'm happy with the way they work.

The polarity pins are reversed for the intel NUC so I had to remove the pins from the connector and swap them around. At first the PC refused to start up and it took me quite a while to figure out what was going on. Very annoying.

I used this to replace the BIOS battery in my Intel NUC5PPYH. It's a perfect replacement, and I no longer have a dead battery warning on power-up. I opened some old netbooks and found that either the polarity or the battery size is different, so you'll want to check your device before ordering. I have a second NUC, so I'll have spares for that in the future. The batteries even have a sticky side to attach to your motherboard. Thanks!

Good

Worked without issue on an old Lenovo laptop. Friendly reminder to those concerned about polarity: the connector pins can be released with a small blade or tweezers and swapped.

便利

Batteries as described and tested 3.3v with a multimeter, my only suggestion would be it would be nice if the yellow plastic cover indicated whether they are Reverse Polarity or not.

Perfekt!
