Why is my drone battery not charging?

The problem may be due to an outdated firmware, a damaged battery, or a faulty internal connection. There are simple solutions for most of the problems. You need to check the charging cable or battery, and if nothing works, seek professional help. They will help you identify the problem and fix your drone.

8 Tips To Fix the Drone Battery Not Charging Issue

1. Check the charging cable and adapter

A faulty charging cable or adapter is the major cause of drone charging issues. Over time, the cables can become frayed, and the adapters can stop working because of a power surge or any type of internal fault.

Steps to perform:

Check the charging cables for any broken pins
Try using a different USB cable or changing the adapter to resolve the issue.
Make sure that the adapter has the correct voltage and current, which is recommended by the drone manufacturers.

Note: Never use uncertified third-party cables as they may not deliver correct power and can damage the device.

2. Remove dirt from battery connectors

Dirt, dust, or any kind of small debris on the battery terminal can damage the connection between the charger and battery, which prevents it from charging.

Steps to perform:

Use a soft cloth or any cotton swab, and put a little rubbing alcohol to clean the battery terminals.
Avoid using excessive liquid when cleaning the controller, and check that the battery is moisture-free before charging it again.
Inspect the battery terminals and the connectors of the drone, and also the charging dock.

3. Cool down the battery

If your battery is swollen or damaged, never charge it. These types of batteries, which are lithium-ion or lithium-polymer, are so sensitive and at a high risk of fire or explosion. It is very important to handle them with care.

Steps to perform:

Remove the battery and let it cool down in a dry place for 30 minutes.
Before charging the battery again, wait for the battery to return to normal temperature fully.

Note: Do not place the battery in the fridge because a sudden temperature change can harm it.

4. Try a different power source

Sometimes the battery or charger is perfectly fine because the power outlet or strip can be faulty.

Steps to perform:

Plug the charger directly into the wall socket and avoid using USB ports on laptops or power banks.
Try all the different outlets to remove any faulty power sources.
If you are using any smart charger with a display on it, check if it shows any error signs, such as overheating, low voltage, cell imbalance, or connection errors.
If any of these problems appear, instantly unplug the charger if it is overheating, cool it down properly, and thoroughly check the battery and the charger for any type of damage.
Never use the battery when overheated. Make sure that the issue is resolved before using it again. If the problem persists, then consult the charger manual or the support center.

5. Update drone firmware

Many drones have a smart battery management system, which is controlled by firmware. If the firmware of your drone is not working or outdated, it may not recognize or charge the battery properly.

Steps to perform:

Connect your drone to its app or the software with your mobile device or computer.
Check for any available firmware updates and install them.
Follow the instructions carefully to avoid damaging your drone.

6. Inspect for battery damage

You should never charge your battery if it is swollen or damaged because these types of batteries, such as lithium-ion or lithium polymer batteries, are very sensitive and at risk of fire or explosion. It is therefore important to handle them carefully.

Steps to perform:

Check for signs of swelling, leakage, or puncture.
If the battery feels soft, discard it immediately.

Note: Dispose of this type of damaged battery at an e-waste or battery recycling center; never throw these batteries in the trash.

7. Try in-drone charging

Some drone models have a feature that allows for in-drone charging. In this feature, the battery is charged while inserted into the drone. This method can help in resetting the connection between the battery and the drone.

Steps to perform:

Insert the battery properly into the drone.
Plug the charger into the drone and then plug it into the wall outlet.
Ensure that all lights and indicators act normally during this process.

8. Seek professional repair

If you have tried all of the above steps but the drone battery still won’t charge, it is time to consider getting professional help. Technicians can test the battery’s voltage and assess any internal issues. Then, they will recommend a solution, which can either be repaired or replaced.

Steps to perform:

Contact the manufacturer of the drone’s support team
Visit a professional and certified drone repair center. If your drone is under warranty, check whether the battery replacement or repair is covered.
Sometimes the drone battery reaches the end of its life. Like all other electronics with batteries, drone batteries also have a limited number of charge cycles, which is usually between 200 and 300 cycles for most lithium batteries.

Signs It’s Time To Replace Your Drone Battery

Below are some of the signs your battery gives when it’s time to replace it:

The battery finishes quickly, even if it is fully charged.
When it is unplugged, it dies at the moment and never holds a charge for more than a second.
You notice an unusual burning smell from the battery area.
The battery swells, which makes it difficult for the case to close.
During charge or light use, the battery overheats fast.
The battery is older and has been used for many years.
The battery is charged very often and is used heavily.

By regularly inspecting and maintaining your battery, you can extend your battery’s lifespan, but when any signs of aging appear, replacing it is the first and safest method.

Conclusion

When your battery is not charging, you should start by inspecting the basic points, such as your charging cable, an adapter, or a power source. You need to make sure that the battery connectors are clean and cool down the batteries after use.

If the problem still exists, you can try updating the firmware of your drone or its battery and try in-drone charging. When you try all these steps but still fail to charge the battery, seek professional drone repair. By following the steps, you can check and fix almost every charging issue, and your drone will be ready for flight.
