Drone batteries typically last 200-300 charge cycles when properly maintained. To maximize lifespan:
Most LiPo drone batteries will show signs of degradation after 150-200 cycles, with capacity dropping to about 80% of original. Never store fully charged batteries for extended periods, as this significantly reduces lifespan. For storage longer than 2 weeks, use your drone's storage charge mode or manually discharge to ~3.8V per cell. Regular visual inspection for swelling or damage is essential for safety.
