Battery Health & lifespan

How can you tell when it’s time to replace a battery.? Age, Charge Cycles, or what? Thanks

The DJI Warranty shows the Phantom 3 battery is covered for 200 cycles. A single cycle is when the battery is charged a total of 100% (which takes at least 2 charges). So, you should get somewhere around 300+ charges out of a battery if you care for it properly.
