Case 1: Let The Batteries Cool Down
One of the major reasons you might be experiencing this is due to the batteries getting heated up. In other words, when you fly the DJI Mavic 3 for some time, the batteries remain heated for quite some extra time.
Meanwhile, if you try to put them on charge just after flying, you will see the LED binks three times, but the batteries won’t charge. In that case, you need to let the batteries cool down and try charging after a while.
Many users have already tried this and have gotten fruitful results. As they mention, you should take the batteries out of the drone or even from the charging hub. Keep them in the open for some time (at least 5 hours recommended). Now, try charging them again; it will probably work out for you.
However, this is just a trial and error method that has proven effective in many cases. But there are no official resolves to it until now. So, we won’t guarantee the same will also fix your issue.
Case 2: New Firmware For DJI Drones
As per the DJI developers team has mentioned, they are already aware of the issue. If the trial and error method does not help you, you might have to wait for extra time.
The developers are working on new firmware, for now, that will focus on optimizing the performance of the device and resolving such issues. There is no fixed date to when this firmware will be launched, but we can only hope it drops out soon.
Case 3: Battery Not Working At All
In the worst scenario, you might face situations when your battery stops working. If you see all the LEDs flashing three times while charging instead of just one, it might indicate some serious issue per a few users’ concerns.
In this case, try connecting the battery to the airplane and take a normal flight. If the battery still works, it is fine; if it doesn’t, chances are your battery might have stopped working.
Case 4: Check Hardware Damage
If none of the above methods help, then your DJI battery might be faulty or have hardware damage. At this point, you have to contact DJI customer care and ask for a battery replacement.
Simply get a picture of the battery serial number showing the problem and mail it as an attachment to support@dji.com. The support team will investigate the issue and provide the required assistance. In case of a technical fault, you might even get a replacement.
Conclusion
Since there are neither any clear fixes nor many alternatives with batteries, you must stick to the same trial and error method for now. However, if your battery does not work, you might also contact the service team and ask for repair or replacement under warranty.
Hopefully, the release of the new firmware will take care of this issue soon. Let us know if it has been helpful or if there are any further queries.
