Hi there, everyone knows that most DJI drones are powered by intelligent flight batteries, so what are we talking about when we call a drone battery as “intelligent”? Let's have a closer look into DJI’s intelligent flight batteries, and this guide walks you through some details, including a brief introduction, common error messages and malfunctions, and battery maintenance and after-sales services. Hope this guide helps in even a little way to better use and service your drone batteries.

A Brief Introduction to Intelligent Flight Batteries
  
For the sake of transportation safety, new intelligent flight batteries are set in Sleep mode before shipment. Therefore, when receiving a new battery, it is required to charge it to wake it up.

Insert the battery into your drone and get started after the battery is fully charged. Connect your drone to the related app, enter the Battery Info page, and you will see the related battery information, including Battery Cell Status, Battery Voltage, Battery Temperature, Battery SN, and Battery Cycle Counts.

Battery Cell Status shows the current number of cells and whether these cells are in a good state. The battery icons on the app change into different colors, from green to yellow and then red, according to the current battery level. If no error messages are prompted on the app, the battery can be used normally.

Battery Voltage is a significant indicator measuring the performance of a battery. On a DJI app, the “Battery Voltage” field displays the sum of cells voltage. You can fly the drone normally as long as no error message is prompted on the app. In case of a prompt saying “Battery voltage difference too large”, it is necessary to fully charge and discharge the battery. If the problem still exists after going through the above step, and your battery is within the warranty, send it back to DJI for after-sales service. If the battery is out of warranty, it is recommended to use other normal batteries.

Battery Temperature displays the current temperature of the battery. If the battery temperature is over 65℃ (149°F), it is suggested to lower the flight speed. If it is higher than 70℃ (158℉), the battery will probably catch fire or even explode. You should check the battery temperature at any time in midflight. If the temperature is too high, land and cool the battery down in time. When the ambient temperature is low, warm up the battery before takeoff. If it is a consumer drone battery, it can be operated at 0° to 40℃ (41° to 104°F).

Battery SN is unique to each battery, also known as the ID card of a battery. If you have multiple batteries, you can distinguish the batteries by their SN. When requesting an after-sales service for a battery, it is required to submit the battery SN.

Battery Cycle Count is the number of times that a battery has gone through a cycle. A battery cycle count is not the times that you charge a battery, but simply refers to the times that the battery consumption accumulates to 75% of the battery capacity. When the battery cycle count is over 200 times, battery performance will decline. In this case, it is recommended to replace the battery with a new one.
Note: For the DJI FPV, it is recommended to replace the battery once the battery cycle count reaches 100.
For the specifications of different intelligent flight batteries, as in, capacity, voltage, and max charging power, please refer to this article “Intelligent Flight Battery Technical Specifications” for help.
*Applicable Products: DJI Mavic 3, DJI Air 2S, Mavic Air 2, DJI Mini 3 Pro, DJI Mini 2, DJI Mini SE,  Phantom 4 Pro series, and DJI Avata.

Common Error Messages and Malfunctions
  
Although intelligent flight batteries cannot speak like a real person, you can also read its status through the status indicators. The indicators can not only tell the current battery level and the on/off state of a drone, but can also be used for prompting error messages. We all know that when a battery is charging, the indicators are blinking in sequence. What if the indicators are not blinking in sequence, or only a certain indicator is blinking, and the device cannot be charged?
ClickAbnormal LEDs Status While Charging and Solutions for details.
*Applicable Products: DJI Mavic 3, DJI Air 2S, Mavic Air 2, DJI Mini 3 Pro, DJI Mini 2, DJI Mini SE, Mavic Mini Phantom 4 Pro, Phantom 4 Pro V2.0, DJI FPV, Spark, and DJI Avata.

DJI’s intelligent flight batteries can not only report an error during charging, but also prompt an error message on the related app if an error is detected when connected to the drone. Check the details below for some common app error messages and solutions.
  
Overcurrent During Discharge
When the discharge current exceeds the maximum discharge capacity of the battery, do not fly aggressively.

Overheating During Discharge
If the battery overheats during discharge, the drone will automatically reduce the power to ensure better battery performance.

Low Temperature During Discharge
If the battery is in an extremely low temperature during discharge, land the drone in time to ensure better battery performance.

Abnormal or Damaged Battery Cell
Stop using the battery, and replace it with a normal one.

Users have reported some battery charge failures on DJI Forum, which were probably caused by the following reasons.
Power Cable/Adapter Malfunctioning: Replace the power cable or battery, and run a cross test to troubleshoot.
Poor Connection Between Battery and Battery Charging Port: If the charging port is dirty, wipe it clean with a dry cloth, and try again.
Battery Over-Discharge: After left idle with a low battery level for a long period of time, the battery may over discharge, and therefore cannot be powered on and charged.
If the battery indeed has a charging failure, and is within warranty, send it back to DJI for after-sales services. If it is out of warranty, it is recommended to replace it with a new one, and properly dispose it.

Swollen batteries were mentioned by users on the DJI Forum as well. As batteries are made up of chemicals inside, improper maintenance, over-discharge, collision, and water-damaged may lead to this problem. If you find that your battery is slightly swollen soon after a flight and it will return to its normal state after left idle, it is a normal phenomenon, please feel assured to use it.
  
However, if the battery is swollen and cannot be restored, do not use it any more. If it is within warranty, send it back to DJI for further diagnosis. If it is out of warranty, replace it with a functioning battery.

Battery Maintenance and After-sales Service

As we all know, batteries are consumables. Due to the chemical characteristics of lithium-ion batteries, the capacity and performance of lithium-ion batteries will naturally decrease as the use time and cycle counts increase. However, if such batteries are properly serviced, its service life can still be extended. Here are some battery maintenance tips. Hope these will help.
1. Always store Intelligent Flight Batteries in a well-ventilated place.
2. Charge and discharge the battery about every three months to maintain good conditions of the battery active materials and extend lifetime of the battery.
3. Cool down the battery after a flight, and then charge it. Otherwise, it may cause damage to the battery.
4. If the battery is stored after completely drained, it may over-discharge and be damaged. The battery will enter Hibernation/Sleep mode if depleted and stored for a long period of time. Recharge the battery to bring it out of Hibernation/Sleep mode.
5. If a battery will not be used for 10 days or longer, discharge it to 40%-65% state of charge (until LED 3 lights up or blinks) for storage.

Note: The remaining part of this article will walk you through the auto-discharge function of DJI's intelligent flight batteries. By saying Battery Auto-Discharging, we mean that the battery will discharge itself to a preset battery level within a specified time. Take DJI Mavic 3 Intelligent Flight Battery as an example, the battery automatically discharges to 96% of the battery level when it is idle for three days, and automatically discharges to 60% of the battery level when it is idle for nine days. To learn more about the auto-discharging function of DJI’s intelligent flight batteries, refer to the following article.

Introduction to DJI Intelligent Flight Battery Auto-Discharging Rules to have a better look into the rules.
*Applicable Products: DJI Mini Series, DJI Mavic Series, DJI Air Series, Spark,
Phantom Series, Inspire Series, and DJI FPV.

Careful maintenance is of course necessary, but accident happens. In case of a battery failure, just feel free to contact
DJI Support for further help. DJI warrants batteries damaged due to non-user errors within warranty. Currently, intelligent flight batteries of most DJI consumer drones, with less than 200 charge cycles, are warranted for 12 months. As the warranty period varies among different products, please refer to the after-sales policies specified on DJI Official Website.

I got a new battery and accidentally turned it on when I meant to just see if the light came on by pressing the button.  It must have used the small amount of power that was in it because when I went to put it on the charger I wasn't getting any light when pressing the button. Now I can't even get it to do anything I'm guessing because I don't have the small amount of power in the new battery for the charger to recognize it.  What can I do?

I've found that my new DJI batteries and RCs will not charge for the first time on any kind of fast/quick charger. They will only charge for the first time on regular, old usb charger. After that, they will charge on a fast charger.
