Watch for these warning signs that indicate your drone battery needs replacement:
- Reduced Flight Time: More than 20% decrease from original duration
- Physical Changes: Swelling, deformation, or damage to casing
- Charging Issues: Difficulty holding charge or unusual heating
- Performance Problems: Voltage sags or power fluctuations during flight
If you notice any of these symptoms, immediately discontinue use and properly dispose of the battery. Most batteries should be replaced after 150-200 charge cycles or when capacity drops below 80% of original specification.
