Watch for these critical warning signs of battery deterioration:
- Significantly reduced flight time (>20% reduction)
- Physical swelling or puffing
- Unusual heating during use or charging
- Difficulty holding charge
- Voltage instability during flight
If you notice any of these signs, immediately discontinue use of the battery. Modern drones often include battery health monitoring through their apps. Regular voltage testing of individual cells can help detect imbalances early. According to battery safety guidelines, any physical deformation is an immediate sign to retire the battery.
