Rome TechCR1220W CMOS Battery for Medion Akoya P2212T S2218 MD99595 - Laptop Backup BIOS RTC 3V CR 1220 Battery with 2 Wire Cable FI Connector (1-Pack)

Got this to replace the depleted CMOS battery in my Intel Compute Stick STK1AW32SC. The connector was a match to the original battery; the lead wires are a bit longer but I was able to coil them up and make it fit, and everything went back together without issues.(I'm sure there are instructions elsewhere but briefly: remove any installed SD card; undo the one screw on the bottom of the unit; use a spudger tool to carefully pry open the case, being mindful that the cooling fan is attached to the top half of the shell and connected by very thin wires; undo the 3 screws securing the CPU heatsink and lift off the heatsink; use a spudger to gently keep the battery end of the main circuit board pried up slightly; detach the battery and unplug the battery; install new battery; clean and reapply CPU thermal paste if needed; reinstall heatsink; snap housing back together; replace screw.)

It took forever to find a new CMOS battery for my HP Mini 311, that being this product. It fits perfectly and works perfectly!

I noticed the date/time in my mini NUC box started showing the date/time that it was last turned off. I turn off my UPS at night and I guess that caused the CMOS battery to run down/go bad. Sure I could just tick "auto date/time" off and back on every time I turned it on, but that would get annoying quickly. This little battery is just what I needed to correct that problem. Easy to install and my mini NUC keeps correct date/time again. Fit was perfect!
