Pleasantly surprised
I was skeptical of an after market battery, but I must say, this has done better than expected. Easily installed in my Asus Vivobook 15, charges quickly and holds the charge. Great price too

Great! 45Wh instead of the advertised 42Wh.
Excellent, almost 45Wh actually. Super easy to install. Comes with screwdrivers and plastic tab openers.

Battery Issue
The battery does not go up to 100 percent or anywhere near 100. After using it for multiple weeks, it usually maxes out at 75 percent charge.
