Mavic 3 Battery Care & Maintenance

Maintaining the battery health of your DJI Mavic 3 is crucial for optimal performance and longevity. This guide will walk you through the best practices for battery care and maintenance, ensuring you get the most out of your intelligent flight batteries.

Understanding the Mavic 3 Intelligent Battery

The DJI Mavic 3 uses a 4S LiHV (Lithium Polymer High Voltage) intelligent battery, featuring 5000 mAh capacity and an overall voltage of 15.4V. Fully charged, each cell reads 4.35V, totaling 17.4V.

This advanced battery system includes an auto-discharging function, which helps to prevent overcharging and swelling by discharging to safe levels when idle.

Long-Term Storage Tips

For extended storage (more than four days), keep the battery at 50-65% capacity. This corresponds to a voltage of approximately 3.85V per cell (50%) to 4V per cell (65%).

Here’s how you can check and manage this:

• Manual Check: Press the battery button once. Two solid LEDs and a blinking third LED indicate the battery is at the optimal storage level.
• DJI Fly App: Navigate to Settings > Safety > Battery Info to monitor the exact voltage levels.
• Avoid storing the battery at full charge for long periods, as it can degrade the battery by around 5% over 30 days. Similarly, keeping it below 20% can also be harmful.

Calibration for Optimal Performance

To ensure accurate battery readings and optimal performance, calibrate each battery every 10 partial charges or at least once every three months.

Here’s how to do it:

• Full Discharge: Perform a hover flight to rapidly discharge the battery until the drone auto-lands and powers off.
• Full Charge: Charge the battery fully before the next use.
• Regular calibration helps maintain the battery’s health and accuracy in reporting the remaining charge.

Warning Signs and When to Discard a Battery

Be vigilant for signs of battery degradation:

• Physical Signs: Puffed, leaking, or broken batteries, and corroded contacts.
• Performance Issues: Sudden drops in power, especially below 30% charge, and significant voltage deviations between cells (check via Settings > Battery Info in the DJI Fly app).
• If you notice any of these issues, it’s time to replace and recycle the battery to ensure safe and reliable operation.

Auto-Discharging Function

The Mavic 3 intelligent battery includes an auto-discharging function, designed to prevent swelling and extend battery life.

Here’s how it works:

• After 3 Days: The battery discharges to 96% of its capacity if idle.
• After 9 Days: It further discharges to 60% if it remains unused.
• This controlled self-discharge helps maintain the battery’s health by preventing overcharging and swelling. It's normal for the battery to emit moderate heat during this process.

Proper care and maintenance of your DJI Mavic 3’s intelligent battery are essential for ensuring long-lasting performance and safety. 

By following these guidelines, storing at optimal levels, regular calibration, monitoring for warning signs, and understanding the auto-discharging function, you can maximize the lifespan and reliability of your drone’s batteries.

FAQs on Mavic 3 Battery Care Best Practices

How often should I calibrate my Mavic 3 battery?

Calibrate your battery every 10 partial charges or at least once every three months to maintain accurate readings and optimal performance.

What is the optimal storage level for my Mavic 3 battery?

Store the battery at 50-65% capacity, which corresponds to approximately 3.85V to 4V per cell, for extended periods.

What should I do if my Mavic 3 battery becomes puffed or leaks?

If you notice any physical damage, such as puffing or leaking, it’s time to replace and recycle the battery to ensure safety and reliability.

How does the auto-discharging function of the Mavic 3 battery work?

The battery automatically discharges to 96% after three days of inactivity and to 60% after nine days to prevent swelling and overcharging.

Why is it important to avoid storing my Mavic 3 battery at full charge?

Storing the battery at full charge for extended periods can degrade its health by around 5% over 30 days, reducing its overall lifespan.
