A DJI drone battery that won't charge is usually in hibernation, outside its charging temperature, or on a charger that can't deliver enough power. Put the battery in the drone or charging hub, keep the drone powered off, and connect a USB Power Delivery charger at room temperature. A hibernating battery wakes up once it charges, and a hot one starts charging once it cools.
1. Wake it from hibernation
Every DJI flight battery ships in hibernation, and it goes back into hibernation if it sits nearly empty. The thresholds vary by model, according to DJI's manuals:
| Battery | Hibernates when |
|---|---|
| Mini 3 | Under 10%, or a cell under 3.0 V |
| Mini 4 Pro | Under 10% while idle |
| Mavic 3 Pro and Classic | Under 5% for six hours |
| Mavic 4 Pro | Sleeps during long storage |
In hibernation the LEDs stay dark when you press the button, so the battery looks dead. Charging wakes it. Give it time on the charger before deciding it's gone.
2. Check the temperature
DJI's batteries only charge between 5° and 40° C (41° and 104° F), and stop if the cells pass 55° C (131° F). The ideal range is 22° to 28° C. Two common traps:
- Right after a flight the battery is too hot. DJI says to let it cool first.
- A cold car or garage leaves it too cold. Bring it inside to warm up.
3. Use a proper charger and setup
- Drone off. DJI says batteries can't charge while the aircraft is powered on.
- USB PD charger. DJI recommends its own chargers or other USB Power Delivery chargers: 30 W for the Mini series, 65 W or 100 W for larger drones. A phone brick may barely charge.
- Good cable. Swap the USB-C cable if charging starts and stops.
- Seated battery. On the Minis, LEDs 3 and 4 blinking together means the battery isn't mounted correctly.
4. Read the blinking lights
The protection codes in the chart above are the same across DJI's current consumer batteries. Unplug and replug the charger to clear overcurrent, short circuit or overcharge. For an over-voltage warning, use a different charger. Temperature codes clear when the battery comes back into range.
All four LEDs blinking together means DJI considers the battery damaged. Stop using it.
Charging hub not charging
Most DJI hubs charge in sequence, so one battery may simply be waiting. The Mini series Two-Way Charging Hub charges the fullest battery first. If all of a hub's LEDs blink in sequence, it doesn't detect a battery: push it in until it clicks. Clean the metal terminals with a dry cloth.
DJI Neo battery not working
The Neo charges inside the drone or in the Neo Two-Way Charging Hub, also between 5° and 40° C, and also can't charge while the Neo is powered on. A battery bought separately may need a firmware update: DJI says to insert it into the Neo and power on, and DJI Fly will prompt you.
When to replace it
- Swollen, cracked, leaking or hot when idle: stop now. See swollen drone battery.
- Won't wake after a long charge on a known-good charger: DJI says to dispose of a battery that can't power on after over-discharging.
- Not charged for months: charge each battery at least once every three months. On some models DJI voids battery warranty after three months without charging.
A spare such as the Mini 4 Pro battery tells you fast whether the battery or the drone is at fault. For storage habits, read drone battery care. If the drone won't power on even with a good battery, see DJI drone won't turn on.
