I just received my new Micromall(TM) CMOS Memory Battery. It worked fine once I got it installed on my Lenovo 430s. I noted that the plug was just very slightly different than the factory original causing it to bind when I tried to plug it in. I was fearful of forcing it because the connection plug on the 430s is really delicate (flimsy).. I removed a very tiny bit of the locking tab from the plug with an X-acto knife it it slid right in. Other than that small drawback it seems to have solved my problem with losing clock setting when ever the main battery was low and the unit was turned off. I would definitely recommend this battery for this model of laptop, just be prepared to do a small bit of easy modification to the plug.

Used it in an odroid c1+ and it seems to do what is required.Good build quality.No complaints.

Lasted 2 days --- BOOOO

Good product, speedy delivery, easy to do business with. What more can one expect?

Direct replacement for the battery on my Thinkpad T20.

It worked ok.
