People appear to be experiencing a problem in which their Mavic Pro and Mavic air’s battery where it does not charge or does not appear to charge even though it is charging.
So I thought I’d compile a list of possible explanations for why it is happening and how you can fix it.
One thing I learned from the past is not to send my drone to a professional because they tend to charge you a lot for a simple fix so
But before we proceed take a look at the precautions you should take when dealing with LiPo batteries first.
- If the charging lights does not appear to be normal, do not leave it unattended.
- Keep flammable materials away from the battery.
- If you notice the battery deforming or expanding, stop the process.
- If the battery is visibly damaged on the outside, throw it away.
- Do not use heat to dispose of a LiPo battery.
Why is your Mavic pro not charging and How do You Fix it?
- The battery is hibernating
- The battery was used until it was flat and then stored for a long time.
- Using a power cable or brick that is not supported
- Battery or charger failure
- piled up dirt in the charging port.
- A faulty piece of hardware inside the drone, such as a frayed wire.
- A software issue that can be resolved with manual update
1. kicking the battery out of hibernation mode
There is a high likelihood that your batteries are not charging simply because they are in hibernation mode, so it is recommended you give it at least 3-4 hours before going further.
You can use a more powerful charger to get it out of hibernation mode faster, the battery supports 12V-1.5A, 9V-2A, and 5V-3A.
Generally, batteries can’t hold a charge if not used and that can decrease their life span, to avoid this problem, DJI introduced hibernation mode.
So, if the battery is not used for a while, it will go into hibernation mode, or different components of the battery will “sleep” to protect the battery from the free flow of charge, which is most likely why your Mavic Pro battery does not appear to be charging.
This is also common when the batteries are still new and haven’t been charged, leading people to believe they received a faulty battery when it is simply in hibernation mode.
Getting the battery out of hibernation mode doesn’t require much energy it just needs patience-
- Switch on battery – one quick press followed by a press that lasts 3 seconds.
- Plug it into your DJI charger.
- The battery will eventually come out of hibernation mode without you needing to do anything, it can take hours.
Note: If you have more than one battery and are charging them with a charging hub, keep in mind that not all batteries will come out of hibernation at the same time; some may take longer, so if some batteries are not responding, give them some time.
2. Flat battery (flat lipo)
Lipo batteries should never be discharged below 3.0V/cell, or they will be permanently damaged.
So if that is the case and your battery is overly discharged it is better to buy a new battery cause it is considered dangerous to try to kick start a lipo battery
3. Clean the charging ports on the Mavic pro
The next step is to clean the ports, to do that grab a small toothpick, or roll a paper or cotton product into a small tip. Carefully insert the tip into the port and jiggle it to loosen dirt or debris. Give the port another burst of compressed air to help remove anything you’ve loosened, do the same for the mini’s port.
4. The battery protecting itself from Overcurrent
DJI smart chargers stop the current from reaching the battery when there is too much current is coming out of your outlet it to avoid damage.
There is no way to fix this problem except to wait until the power outlet returns to normal. You can also try unplugging and replugging the charger after a minute or so. If the amperage still does not regulate, the power outlet could be to blame.
5. Change the charging brick
To get the battery out of hibernation mode you might need more power than usual so if you are not using the charger that came with the drone that can be the issue.
It is preferable to use an authorized DJI charger for this because there is no guarantee that any third-party or phone charger will wake up the battery. You can charge your drone with your iPhone charging brick, but it may require more power than usual to come out of hibernation mode.
The DJI Mavic Pro’s intelligent flight battery supports input of 12V 1.5 A / 9V 2A / 5V 3A.
If you are trying to charge your drone right after it being used is not a good idea and i might not also respond, and that is because the intelligent battery blocks power input if the battery is above a certain temperature, this is done to avoid explosion, swelling, and such.
For this, you don’t have to do anything, unplug it and give it 30 minutes till it cools down then it will start charging normally.
7. Faulty charger
If you are not successful with all the previous steps you might have a faulty charger, how do you check if you have a faulty charger
- Plug the charger into a known-working wall socket and test it by plugging in your phone.
- Turn on the battery and plug it in. Before connecting, the flat on the battery should be flashing red.
- If the battery continues to flash red after red, it means the charger is broken, and there you have it.
Another great way to check if a charger is dead is by using a voltage tester.
8. Dead battery
Battery damage can be caused by age, physical damage, or poor battery maintenance and it might be time to buy another battery
There is no way to check if your battery is dead except when you turn it on if it doesn’t flash red that is a sign it might be dead but you can’t be sure
But if the battery has had a short life for the past weeks or if it discharges randomly it was a sign it is old and needs to be changed.
Mavic pro batteries are sold for about $70 on Amazon, but before you buy a replacement to make sure it is the charger that is not working try different chargers.
9. Refresh the batteries firmware
So if you can somehow get the battery out of hibernation and charge it to 30% you should defiantly do a firmware refresh to prevent this problem in the future
watch the video below which shows you how you can refresh your batteries firmware
If DJI go tells you to update the batteries firmware great if not connect your drone to DJI assistant and do a firmware refresh with every battery you own.
If none of the methods work, you may need to send it to DJI, in which case, if the battery is new and you purchased it from DJI, they will send you a replacement at no cost.
After you return it to DJI, it may take up to 15 days for them to send you a replacement, and it may take longer if you live outside of the United States.
If you live in Armenia, you can start a case and return the unit by emailing the local dealer or DJI’s support.
