Review: Worked for what I needed. - Worked for what I needed. Replaced CMOS battery
Review: Awesome deal on some high quality NUC6CAYH batteries. 3.35+ volts - 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.
