This is a 3rd party Lenovo battery with the part number L22C3PF2. It's brand new in box, the anti static bag has never been opened.I will leave it up to you to figure out if your laptop is compatible with this battery. I really don't know much about these. Amazon inexplicably sent me this without me buying it and they don't seem to want it back, so here it is for cheap.Feel free to message me with questions. Thanks for looking.
