❓ What are the signs of a failing drone battery?

Watch for these critical signs of battery deterioration:

• Reduced Flight Time - More than 20% decrease from original duration
• Physical Swelling - Any visible puffing or deformation
• Irregular Behavior - Sudden power drops or voltage fluctuations
• Charging Issues - Difficulty holding charge or unusual heating

If you notice any of these signs, replace the battery immediately. According to NASA research, battery failure is a leading cause of drone incidents. Most manufacturers recommend replacement after 150-200 charge cycles or when capacity drops below 80% of original specifications.
