❓ What are the signs that a drone battery needs replacement?

Watch for these key indicators that your drone battery needs replacement:

• Significantly reduced flight time (>20% decrease)
• Physical swelling or deformation
• Difficulty holding charge
• Age exceeding 300-500 charge cycles
• Unusual heating during use or charging

Modern drone batteries typically last 1-2 years with regular use. If your battery shows any of these signs, especially physical damage or swelling, discontinue use immediately. Most manufacturers recommend replacement after 300-500 charge cycles or when capacity drops below 80% of original performance.
