I picked up a used spare battery with only 1 charge cycle. It charges and discharges fine but the battery will cause the front loading screen on the DJI app to state that it needs an update.  When I click the update it appears to work and then the update button shows up again.  If I go back to the main screen it still requests and update.  My original 2 batteries do not do this.  

Battery: 3QFPHBHCA404AT

The battery information in the DJI fly app all appears proper.  Is it possible that this is a fake battery or is it not functioning properly?

Hi there. Kindly check the suggestions posted in this post. Thank you, and have a nice day.
