Works Great, But Cable is Long
It works very well and immediately fixed my clock/BIOS setting issues. My only note: The cable is significantly longer than the original.

Nice replacement part that I am unable to fully test.
It's a good fit and the laptop stopped yelling about the CMOS battery, unfortunately, lenovo designed the laptop to basically become a spare parts machine once these go totally dead, but that's a different story I guess.

Great battery to bring back life to my old electronics.
It was great to find a vendor who carried this battery replacement. The value for the money was good and the product was well packaged. The battery seems to me of good quality.

Fixed CMOS battery issues
It works as expected. Fixed my Lenovo X1 Carbon Gen 8’s timestamp issues at start up. It’s been 2 weeks after I replaced the CMOS battery and I’ve not had any issues

Works well
Just a watch battery. Might only need to replace once or twice in your lifetime (average user) but it does it's job.
