The DJI Spark is a great little drone that has been around for a long time now. I can still see people flying it around.
Lately, people have been experiencing issues with DJI Spark battery not charging. There are a number of reasons for that and we are going to troubleshoot the issue in this article.
The most common reason for DJI Spark battery not charging is because it was stored for a long time without intermitent charging and now it is completely depleted. Other resons might be hibernation mode, faulty chargers and damaged pins.
Let’s look at the possible causes of unresponsive DJI spark battery and see how we can fix it.
DJI Spark battery not charging – Reasons
Below are 8 reasons your DJI Spark battery is not charging and unresponsive. I have arranged the list from most likely to least likey so that you can start with the most common fix first.
1. Battery is fully depleted
Most of the users I have talked to about this issue during my research for this article have stored their batteries for a prolonged time without intermitent charging & maintenance.
LiPo batteries are very sensitive to low and high charge. If you store them for a long time in either state, they are going to permanently degrade. That’s just the physics of it.
The DJI smart batteries (like the ones in your Spark) have internal smart circuitary to protect the cells from high and low charge status. But that feature too has limitations.
If you store your battery with a 100% charge level, the smart feature in your battery will automatically discharge it to a safe 65% charge level meant for long storage.
However, most people keep their spare batteries on shelf and forget about them for years. During such prolong time, the battery will discharge to critical level and its cell chemistry is destroyed.
When that happens, its almost impossible to revive your battery.
If you are picking up such a battery that has been on the shelf for more than a year, chances are it will not wake up.
- When you push the battery power button, nothing will happen. You won’t see any LED flashing or any kind of life. That’s because there is no charge left even to light up the LEDs.
- When you plug in the charger, the LED 1 and 2 will flash for a few times, turn off and than repeat the same. That’s the charging circuit trying to give your dead battery cells CPR albiet unsuccessfully.
I talked to the DJI support team and they just told me that my batteries are dead due to incorrect storing for a prolonged time and that I should buy new batteries.
I also searched the forums to see if anyone has any unofficial “hack” that can be used to revive dead batteries. I did find a few ways people have been able to revive such batteries.
Although these methods worked for some and not for others, you can still try and see if you can revive your batteries
- Use a high ampare charger to revive the dead battery. You can go up to 3A 5V charger and see if that is able to power it up.
- Connect the battery to your laptop and leave it for charging. This might sound weird but a few users were able to revive their batteries this way.
- Leave your battery for charging overnight even if it doesn’t show any signs of charging. If the battery is not completely dead but in hibernation mode, it will spring back to life.
If none of the above method work, you can assume that your battery is dead beyond repair.
But if you are a DIY person, you can carefully take the battery apart and check the 3 cells inside.
One user who did this found out that 1 out of 3 cells was swollen and the rest of the 2 cells were fine. He just disconnected the swollen cell terminals and the battey started charging.
2. Battery in hibernation mode
Hibernation mode is a protective feature inside DJI Intellegent Flight Battery that puts the battery in ‘sleep’ when it is not used for sometime. In hibernation mode, the battery circuit will not draw any current to prevent overdischarge.
Specially during shipment, all DJI batteries are put in hibernation mode. This helps prevent overdischarge during long shipments.
When a battery is in hibernation mode, you won’t see any LED flashing when you press the power button. It might seems pretty much dead to you.
But it isn’t. Its just sleeping.
To get the battery out of hibernation mode, all you have to do is connect it with the charger and leave for a good 6-8 hours to wake up.
During this time, you might not even see any charging activity on the battery. But do not remove it and let it be for atleast 8 hours.
Once out of the hibernation mode, it will wake up and behave normally.
3. Outdated battery firmware
Another reason for an unresponsive battery is outdated firmware. If your battery has some power left but is not charging, this might be the reason.
Solution is pretty simple. Put your battery inside the drone, connect your drone with your phone and see if it has a firmware update available. If it prompts you for update, update it.
But of course if the battery is completely dead, you can’t use this method.
4. Charger is not providing enough current
It is always recommended to use DJI official charger for DJI Spark and other drones. But if you are using a third-party charger to try waking up your battery, this could be the problem.
It is possible that the charger you are using is either damaged or not rated for high current high voltage required for DJI Spark.
If you have the official DJI Spark charger, use that else try using a compatible charger that can provide 3A current at 5V to your drone.
5. USB cable is damaged
If the charger is compatible, the next thing you should check is your USB cable. If you are using a cheap USB cable, that can also hamper your DJI Spark charging.
Since USB cables are pretty common in any household, you can try a few cables and check if any of them work. Else, just order a new one from Amazon and try with that.
Since the Spark uses microUSB which is something that has been replaced largely by USB C connectors, some people tend to use a USB-C to microUSB converter and that can also cause problems.
DJI Spark will draw a larger current (5A) so make sure the USB cable you are using is of high quality and avoid connectors if possible as they tend to heat up and can be damaging to your drone.
6. Physical damage to drone or battery
If you have crashed your drone and have physically damaged the drone or the battery, that can also be the reason for your DJI Spark battery not charging.
Inspect your drone carefully and try to assess the extent of the damage. If. you see clear signs of deformation on the battery pack, I would assume disposing it safely as it is not safe to use anymore.
Even if you don’t see clear signs of damage on the body of the drone or the battery, there might be damage to the internal circuitary.
If your drone is in warranty, you can contact DJI else seek out a local repair shop that can have a look at your drone.
7. Temperature too high or too low
Charging a battery that is too hot or too cold is a bad idea. At extreme temperatures, the cell chemistry is unpredictable and can lead to permanent damage. To avoid this, there are temperature sensors built into your battery pack.
Your DJI Spark battery will only charge when the cell temperature is above 5°C (41°F) and below 40°C (104°F). If you are trying to charge outside of this range, your battery will simply refuse to charge.
If you check the DJI Spark LED status table, you will see that the last LED bliking is indication of extreme temperature range. If it blinks twice per second, your battery is too cold. If it blinks 3 times per second, your battery is too hot.
Some people try to charge their battery right after a flying session when the battery is all heated up. Tha’ts a bad practice and should be avoided. Always charge your battery when it is rested for a good few hours after flying.
8. Dirty charging port
Last but not least, if your battery is not reponding to the charger, do check your charging port terminals. Sometimes, its just dirt that is preventing a good surface contact between the terminals.
You can use a connector cleaner like DeoxIT Gold to clean the connector surfaces and try charging again.
DJI Spark battery not charging – Final thoughts
If you try all the above solutions but still couldn’t revive your dead battery, its perhaps time to order a new one from DJI or from their Amazon store.
- 16 min flight time.*
- 12 intelligent protection functions.
- Check flight time left in real-time.
Batteries are critical components and need great care. It is always best to follow the manufacturer’s recommendation specially when it comes to storing your batteries properly.
I hope this guide was helpful. If any of the above method helped you revive your battery, do mention it in the comments and let other people know as well.
