Troubleshooting a Non-Working DJI Drone Battery

Encountering issues with your DJI drone’s battery after a few years of inactivity can be frustrating. This article will guide you through the troubleshooting process, focusing on common issues and solutions. Whether the battery or the charging equipment is the problem, we’ll walk you through the steps to ensure your drone is ready to fly again.

Common Issues with DJI Drone Batteries

If your DJI drone battery is not working after a period of disuse, the primary culprits are usually the battery itself, the charger, or the charging cable. Here’s how to identify and resolve these issues:

Step 1: Check the Battery

One of the first things to check is the battery. Newer DJI drone batteries are designed to be relatively durable, but they still need proper maintenance. Allow a discharged battery to rest for about 25% charge before the next use to ensure its internal chemistry is well-maintained.

Step 2: Assess the Charger and Charging Cable

Using a basic multimeter to test the charger and charging cable is an easy way to determine if they are functioning correctly. A general rule of thumb is that if you can’t get the battery to charge, the charger or the cable could be the problem.

Step 3: Check the Battery’s Smart CPU Function

DJI drones use “smart” batteries with a CPU that will automatically discharge the battery to a ‘storage charge’ level (

Preventative Maintenance for LiPo Batteries

Lithium Polymer (LiPo) batteries, commonly used in drones, require special care to prevent damage and maintain performance.

Practice Regular Use and Storage

LiPo batteries can’t sit in a discharged state for extended periods. Ideally, they should be used regularly and kept at around 25% charge before storage. This helps to avoid the risk of permanent damage or permanent low capacity. Regular use also prevents the battery’s internal components from deteriorating.

Handle with Care

LiPo batteries are made up of hazardous chemicals and can be dangerous if mishandled. Do not allow the battery to sit fully discharged, and avoid overcharging or over-discharging. Overcharging can lead to a catastrophic failure of the battery, while over-discharging can reduce its lifespan significantly.

Store Batteries Properly

When storing a LiPo battery, it’s recommended to leave it at a 50% charge. Avoid exposing the battery to extreme temperatures and keep it in a fireproof container, such as a battery box.

Special Considerations: Resuscitating a Discharged Battery

There are special balancing chargers that might be able to revive a completely discharged LiPo battery. However, it’s important to note that using these chargers comes with inherent risks. Incorrect use can lead to a fire or explosion. It’s crucial to follow the manufacturer’s instructions meticulously and to exercise caution when dealing with LiPo batteries that have been discharged completely.

Conclusion

In summary, if your DJI drone’s battery isn’t working, follow these steps to troubleshoot the issue. Check the battery, charger, and cable, and ensure proper storage and maintenance to keep your LiPo batteries in top condition. Remember, proper care can significantly extend the lifespan of your drone’s battery and ensure safe and reliable performance.
