Not compatible with windows 8.1 & 10. Sometime the os detect the battery. Most of the time nothing detected. I have tried different usb port and cable. I tried with 2 other computer same problem. The battery itself is really good but if a power drop occur the computer will not shutdown because of a software driver problem... I'm not the only one with that problem. Be aware if you buy it.
