Battery Care and Maintenance
Battery Firmware
You should always have your batteries on the same firmware version as your aircraft, and both
ideally on the latest official firmware. For drones with dual-battery design, both batteries need to
be on the same firmware version otherwise you cannot take off. You can find the latest official
firmware by navigating to the product page on the DJI website, going to the Downloads section,
and viewing the Release Notes. Within the Release Notes, you can see the latest firmware
versions.
To confirm your aircraft and battery are on the latest firmware you can open the DJI Pilot app,
go into your manual flight camera view, click on the three dots in the top right, then the three
dots in the side menu, scroll down to the “About” option, and click to view current firmware
versions. You can also connect your mobile device (Smart Controller, Crystal Sky, etc…) to the
internet and when you turn on the aircraft and open the Pilot app you will be notified of any
necessary updates.

If you are updating your aircraft using DJI Assistant 2 or the DJI mobile app, the battery that is
powering the aircraft will be updated if the firmware update includes a battery update or if the
battery firmware is not on the latest version. Assuming there was a battery update as part of the
firmware update, when you place a non-updated battery into the drone you will get a notification
stating inconsistent firmware and allowing you to update the battery based on the aircraft’s
current firmware. In this case, no additional connections to the internet or DJI Assistant 2 are
required for this battery update with an already updated aircraft.
You can also update the firmware of your TB60 batteries (used with the M300 RTK), by placing
them in the BS60 Battery Station and connecting the Smart Controller Enterprise to the battery

station. Up to 8 batteries can be updated at once in the health management system of the Pilot
App.
Battery Charging
Always use a DJI approved charger. DJI takes no responsibility if a battery is charged using a
non-DJI charger. DJI batteries are built to communicate with DJI chargers.
One issue with third-party chargers is their charge rate can be greater than 1C. Though the
battery is charged faster, a charge rate >1C will reduce the service life of the battery and cause
damage to the cells due to excessive internal temperatures and/or lithium-plating. You can
calculate the charge rate for a charger by dividing the amps output from the charger by the
capacity of the battery. For example, with the DJI Mavic 2 Enterprise Battery Charger =
(3.41A/3.85A = .88C). Third-party chargers may also damage the terminals of the batteries as
well due to improper alignment, safeguards, and guides.
There is protection built into DJI chargers and batteries in regards to making sure batteries are
not charged at incorrect temperatures. We cannot cannot guarantee this feature will work with
third-party chargers. In some situations, it is critical to get batteries charged as soon as they are
at an acceptable internal temperature, and with a DJI charger it is ok to place a battery on the
charger after a flight as long as the charger and battery are placed in a well-ventilated area (i.e.
not covered or heated). If the charging need is not immediate, it is best practice to allow the
battery to cool down before placing it on the charger.
The intelligent flight batteries are designed to stop charging when full. However, it is best
practice to monitor the charging progress and disconnect the batteries when fully charged.
Battery Storage
The ideal storage temperature for DJI batteries is between 71.6°F and 86°F (22°C to 30°C).
Though this may not always be possible, it is important to avoid habits such as storing batteries
in vehicles that will routinely get very hot or very cold and are outside the recommended storage
temperature. Always store batteries in a well-ventilated place away from direct sunlight and heat
sources. Remove batteries from drones when storing. Do not allow batteries to get wet. Storing
batteries at a proper temperature can help minimize non-recoverable capacity loss.
DJI Intelligent Batteries automatically discharge to protect the integrity of the battery cells. In
most cases, you can set a time from 1 to 10 days in the app for the batteries to start
self-discharging themselves down to 60%. If there is no option present in the app the battery will
default to 10 days. If a battery is below 40-60% it should be charged until it reaches this range
for storage.

For users who require batteries to always be at 100%, it must be understood that this will
negatively affect the life and performance of lithium-ion batteries. When a battery is at 100% it
places stress onto the cells and leaving that stress on the cells will accelerate a decrease in the
batteries’ capacity and operational life cycle.
We understand some operators such as public safety agencies are required to maintain their
drones and batteries in ‘ready to fly’ condition at all times but do encourage teams to explore
options for charging in the field to potentially allow the storage of some batteries at 60% instead
of 100%. If the decision is made to keep a battery at 100%, it can be stopped from discharging
by pressing the power button on the battery. This causes the battery to exit the idle state and
resets the time to battery self-discharge to the previously defined time period i.e. 10 days.
Battery Handling
Take care not to drop batteries even when they are inside cases. Do not stack heavy items on
top of lithium-ion batteries or cases containing lithium-ion batteries. This can damage the casing
surrounding the battery cells which can lead to a short circuit.
Battery Use
Make sure the battery is fully charged before each flight.
Over-discharge can seriously damage the battery. Therefore, it is recommended to land the
drone when the battery level is ~15% or greater to maximize the service life. If battery levels are
depleted past ~15% please charge the battery as soon as possible.

For aircraft with a dual-battery design such as the M300 RTK and M200 Series, mark two
batteries as a pair and continue using them as a pair (charge and discharge them together) to
maximize the service life and ensure flight performance. Using this method the pairs will
maintain very similar internal resistance.
In a low-temperature environment, the TB60, TB55, TB50, and M2E batteries have a
self-heating feature. Once the battery is installed on the aircraft and the power is turned on, if
the battery’s temperature is low, it will automatically self-heat to keep the temperature at about
60.8°F to 68°F (16 °C to 20 °C). However, this self-heating will consume the battery power so
the flight time will be reduced. Therefore, to maximize flight time or when using batteries without
a self-heating feature such as the Phantom 4 models, it is suggested to heat the battery with an
external heat source such as warm air inside a vehicle.
The self-heating function for equipped batteries can also be manually turned on by pressing and
holding the power button (see below chart). This will keep the battery at an ideal temperature
range for 30 minutes. The self-heating function can be turned off by holding the power button.

Battery Maintenance
The steps below are critical to making sure your batteries are ready to go and are properly
calibrated. Specifically, charging and discharging the battery ensures an accurate digital readout
of battery percentage which is a vital metric when operating your drone. If this process is
ignored the battery percentage margin of error will be amplified by continued operations.
Complete the following every 3 months or 50 cycles (whichever comes first)
1. Charge and discharge batteries per instructions below.
2. Make sure the cell voltage difference is less than 0.1V after the battery is fully charged
and left stationary for 6 hours.
3. Make sure the battery is not swollen, leaky, or damaged. See section: “Battery Issues:
Signs to Look For” below.
4. Clean battery terminals with a clean dry cloth and make sure they are clean.
5. Make sure battery firmware is updated to the latest version. See section: “Battery Care
and Maintenance: Firmware”
Charge and Discharge Instructions:
1. Charge the battery to 100% and leave the battery stationary for more than 24 hours.
2. Install the battery into the aircraft. Fly the aircraft and when the remaining power level is
less than 20%, land the aircraft and remove the battery.
3. Leave the battery stationary for more than six hours.
4. Check cell voltage.
5. Charge the battery to 100% power level.
6. Repeat the above steps 1-4.
Battery Retirement
Properly utilizing, handling, and storing batteries will ideally allow for 200 charging cycles before
a battery should be taken out of service. Retirement of batteries based on a cycle count is a
difficult gauge to go by as there is no standard as to what defines a cycle, for the case of a DJI
battery it is any time the battery is charged. It is also important to look for any other issues that
may be present (which we detail in the next section) when making a battery retirement decision.

Battery Issues
Signs to Look For
Batteries should be taken out of service and replaced under the following circumstances:
- Visibly swollen, leaking, or damaged (cracks, dents, etc…).
- Bent terminals (could cause a short circuit)
- There is an in-app notification/prompt regarding battery cell damage or over-discharge
- 200 cycles
- Battery error still exists after performing the standard charge and discharge operations
twice continuously.
- Crash or hard impact.
Communicating with DJI
Reach out to our support team at [email protected] with any battery issues. If your battery is
within warranty (6 months and under 200 cycles) our team will provide instructions for
replacement.
Battery Disposal
Step 1. Place the battery into the aircraft or use the battery to charge a mobile device via a
Battery to Power Bank Adapter, discharging the battery until the battery turns off.
Step 2. Immerse the battery in saltwater with a concentration of 5% (for example, the mixture of
50 grams of salt and 1 kilogram of water) for 8 to 12 hours, to fully discharge the battery. Then
the battery can be regarded as safe. Saltwater must be used to immerse the battery. With
tap water, the battery cannot be fully discharged and such operation may even cause a
potential safety hazard.
Note: If the battery is too swollen to be installed into the aircraft to be discharged, or it just
cannot be turned on, please directly immerse the battery into saltwater with a concentration of
5% or so for 24 to 48 hours to get it fully discharged.
Step 3. After the battery is fully discharged, please dispose of the battery in accordance with
local regulations regarding battery recycling and disposal in your area. DJI will take no
responsibility for any accidents or issues caused by customers continuing to use a swollen
battery.
