Rome Tech CR2025 CMOS BIOS Battery for Lenovo Yoga 720-12IKB - Laptop Backup 3V RTC CR 2025 Battery with 2 Wire Cable

After tearing down my old HTPC after 5 years of loyal use, I upgraded the CPU to find that every time I unplug it I lose my OC settings. I was a little peeved when I realized this was a soldered CMOS instead of the standard button in a holder on the board. Then after research I found out my Asrock B450 itx Mobo also needed reverse polarity which made it even more of a needle in the haystack.This did the trick, over night shipping combined with wiring as promised, it solved my issue. Can't speak to longevity of course, but for $10 by the time I replace this again, it will be time for a new mobo anyway.Added plus, the double sided tape made it suuuuper easy to remount this right where the old battery was attached. No complaints from me.

This worked perfectly to replace a dead BIOS battery in my Intel NUC computer!

Worked for ASRock Z490M-ITX/AC. The polarity matched. If you have graphics card with the motherboard, you will have to remove it to replace the battery.

I ordered two of the same ones and the polarity was reversed on one of them. Thankfully we checked it before installing it. Other than that, they seem to be working okay.

I receive the battery very quicky and the replacement were very fast. Instructions and data for the replacement were very clear.I will buy again

Saw some reviews about reversed wiring, however, that was not the case for me. I received the battery plugged it in and computer functioned perfectly fine. No issues at all.

I feel stupid trusting the seller and/or the manufacture.Now my NUC motherboard seems to be dead now. It can no longer boot up.Whoever manufactured this piece of cxxp, please check the pictures.The black battery on the left is the original battery on my NUC.The yellow piece of cxxp is yours and the polarity is inverted!Amazon, please stop selling this!!!

Worked perfectly with Asrock B550i Phantom Gaming motherboard. Polarity was correct.
