How to check compatibility
Verify your laptop model matches one in our compatibility table above. Check the label on your current battery for “Medion-A31-M15-42Wh20mm” or “40068772”. You can also find your model number on the bottom case of your laptop or in system information (type “msinfo32” in Windows search).
