Worked Perfect for M17 Alienware
Worked as expected. Good fit and glad it included a 3M sticky on the back to stick to motherboard.

Works on my old Alienware laptop. Lasts around 2 years.
Is your PC kicking off one of those dreaded CMOS errors that sounds serious but only means the battery needs to be swapped out? This will fix it. The last one i bought lasted about 2 years. My Alienware had zero issues recognizing it.

CMOS Battery replacement for Alienware M15
Had to replace the CMOS battery in my son's Alienware M15 and this worked perfectly. Couldn't ask for anything else.

It just works
It is exactly what it says it is, and is far cheaper than the OEM version.

Battery was stuck to tape!!!
Battery was stuck to adhesive tape, therefore when slicing through the thin layer of tape alone I cut the wires going to the battery right in half and didn't even know it. One strip of tap securing the battery could have prevented this from happening. I am skilled enough to have soldered the wires together, provided insulating tape and installed the battery anyway, works fine but more work than needed.
