One of the most important factors of a drone is the flight time, which heavily depends on the drone battery. Drone batteries play a significant role, and therefore, knowing how to take care of them is important to prevent any accidents or malfunctions. If not maintained properly, drone batteries can overheat and cause fires.

Drones have a lot of small parts, and each part has a specific function. The motors are responsible for the movement of the drone; propellers provide lift, and batteries supply power to the motors and other electronics. Just like any other battery-powered device, drones need regular maintenance to function properly.

The batteries of drones can easily be damaged if not used or stored properly. There are certain things you should do to ensure the longevity and safety of your drone batteries.

From storing the batteries in a cool and dry place to regularly checking them for any damage, here is a detailed care guide on how to maintain drone batteries.

Tips and Tricks To Maintain Drone Batteries

Some simple tips and tricks can help you maintain your drone batteries in tip-top condition. By following these tips, you can extend the life of your drone batteries and make them last longer.

Here are some maintenance tips for drone batteries

Only Charge a Day Before Flying

Charging a drone battery days or weeks before you actually need to use the drone can damage the battery. The battery will slowly discharge over time, and this can cause it to form crystals on the electrodes. These crystals will prevent the battery from holding a charge in the future.

If you know you won’t be flying your drone for a while, it’s best to remove the battery and store it in a cool and dry place. The best practice is to charge the battery the day before you plan on flying.

Do Not Overcharge or Discharge

Overcharging and discharging a drone battery can damage it and reduce its lifespan. When a battery is overcharged, the voltage level exceeds the limit, and this can lead to electrolyte leakage and degradation of the separator.

On the other hand, if a battery is discharged below 2.5 volts per cell, it can cause irreparable damage to the battery. It’s important to keep an eye on the voltage level of the battery and stop charging or using it once it reaches the full charge or discharge level.

Store in a Cool and Dark Place

When not in use, it’s important to store drone batteries in a cool and dark place. Batteries are especially susceptible to damage in extreme weather, which can cause the battery to swell or leak. Store the battery in a temperature-controlled environment and make sure it’s not exposed to direct sunlight.

The ideal storage temperature for drone batteries is between 15 and 25 degrees Celsius. Problematic temperatures are below freezing or above 80 degrees Celsius.

Check for Damage Before Each Flight

Before each flight, it’s important to check the battery for any damage. Inspect the battery for any swelling, leaking, or discoloration. If you notice any of these signs, do not use the battery and contact the manufacturer.

It’s also a good idea to check the terminals for any dirt or corrosion. Clean the terminals with a cotton swab dipped in vinegar if necessary.

Keep The Firmware Update

Firmware updates are important for the proper functioning of any device, including drones. New firmware updates can improve the performance of your drone and make it more efficient.

Many manufacturers release new firmware updates on a regular basis, and it’s important to install them as soon as possible. You can usually find the latest firmware updates on the manufacturer’s website.

Charge The Battery At Once

The best way to charge a drone battery is to charge it all at once. This might seem like a time-consuming task, but it’s actually the best way to prolong the life of your battery.

When you charge the battery in stages, it can damage the cells and reduce the overall capacity of the battery. So, if you have the time, it’s best to charge the battery all at once. The reason for this is that charging in stages can cause what is called voltage depression.

Use The Brand's Original Chargers and Cables

It’s important to use the original charger and cables that came with your drone. Using third-party chargers can damage the battery and void the warranty. If you need to replace the charger or cables, make sure you buy them from the same manufacturer.

The reason behind this is that each manufacturer has its own charging specifications. Using the wrong charger can damage the battery and reduce its lifespan. Different chargers have different flow rates, and this can cause the battery to overheat.

So, make sure you use the right charger for your drone. Charging batteries is a complex process, and it’s important to follow the manufacturer’s instructions to prevent any damage.

Do Not Charge Batteries Instantly After Flying

It’s important to let the battery cool down before you charge it. This is because charging a hot battery can damage the cells and reduce the overall capacity of the battery. So, if you have been flying for a while, it’s best to wait for the battery to cool down before you start charging it.

If you are in a hurry, you can charge the battery but make sure you don’t exceed 80% of the battery's capacity because this can also damage the battery. Batteries get heated while charging, which is why it’s important to charge them in a cool and well-ventilated area.

Balance The Cells Before Storing

If you are not going to use the battery for a while, it’s important to balance the cells before you store it. This helps to maintain the health of the battery and prevents any damage. You can use a balancing charger to balance the cells.

Many manufacturers offer balancing chargers as an accessory. If you don’t have a balancing charger, you can also use a standard charger, but it will take longer to charge the battery.

Use a Storage Case

If you are not using the battery for a while, it’s important to store it in a storage case. This helps to protect the battery from any damage. Many manufacturers offer storage cases as an accessory. You can also use a standard case but make sure it’s well-ventilated.

Do Not Fully Charge Batteries That are To Be Stored

If you are not going to use the battery for a while, it’s important to store it at 50% of its capacity. This helps to prolong the life of the battery. When you store a battery at 100% of its capacity, it can damage the cells and reduce the overall capacity of the battery.

So, if you are not going to use the battery for a while, make sure you charge it to 50% of its capacity before you store it.

Keep Using The Batteries Every Once in a While

If you are not going to use the battery for a while, it’s important to keep using it every once in a while. This helps to maintain the health of the battery and prevents any damage.

You can use the battery to fly your drone, or you can charge it to 50% of its capacity and then discharge it completely. Doing this once a month is enough to maintain the health of the battery.

Hi, my name is Richard J. Gross and I’m a full-time Airbus pilot and commercial drone business owner. I got into drones in 2015 when I started doing aerial photography for real estate companies. I had no idea what I was getting into at the time, but it turns out that police were called on me shortly after I started flying. They didn’t like me flying my drone near people, so they asked me to come train their officers on the rules and regulations for drones. After that, I decided to start my own drone business and teach others about the safe and responsible use of drones.
