Drone or camera battery is swollen

Symptoms

• Battery case appears puffed up or bulging
• Battery doesn't sit flush in its compartment anymore
• Battery cover is difficult to close or has popped open
• Battery feels warm even when not in use

Likely causes

• CommonBattery aging and naturally degrading with charge cyclesLithium batteries can swell as their internal chemistry breaks down over time.
• CommonRepeated full discharges or overchargingPoor charging habits accelerate cell degradation and swelling.
• PossiblePhysical damage or puncture to the batteryImpact can compromise the internal cells and cause gas buildup.
• PossibleExposure to extreme heat or direct sunlightHigh temperatures accelerate chemical breakdown inside the cells.
• Less commonManufacturing defect in the battery cellsSome batteries fail prematurely due to a defect.

What to do

1. Stop using the battery immediately and do not attempt to charge or discharge it further.
2. Move it to a fireproof or non-flammable surface, away from anything combustible.
3. Do not puncture, crush, or attempt to open the swollen battery.
4. Keep it away from heat sources and direct sunlight while awaiting disposal.
5. Contact your local hazardous waste or battery recycling program for safe disposal, since swollen lithium batteries can't go in regular trash.
6. Do not attempt to fly the drone or use the camera again with that battery.
7. Order a genuine replacement battery rated for your specific device once the old one is safely disposed of.
