DJI Mini 2 Charged Batteries Not Working

Your battery may be rendered dysfunctional for a number of reasons. Possible causes include:

• The drone has flown in damp conditions or areas, including fog.
• The drone has been kept in an area that's too hot or too cold.
• The drone has been left plugged in for too long.
• The batteries were not given a proper “cooling time” before being charged again.
• If you left the batteries in the charging hub or the drone, they would not discharge. And as you probably already know, storing the batteries when fully charged could damage them. You had to remove the batteries from the hub or the drone for them to discharge.

If a battery is broken, it must be replaced. To replace a battery please refer to our battery replacement guide.

If you’ve not updated your firmware, this could be one of the reasons your drone is not powering up. Connect the drone to the DJI Fly app and the app should notify you that an update is needed. The app will guide you through the updating process.

If the charger is unable to be used on any device, the charger may be broken and will need to be replaced. Here is the link to our main board replacement guide.

Once you’re sure the batteries are okay, the issue could be dirt and debris in the battery port. To clean the connects spray them with compressed air from a compress air can. Or worse, some of the pins could be damaged. If the pins are damaged, seek a professional for help.
