I purchased my Mavic 2 Zoom in 2020 with battery #1. Over the years we had many happy flights together. Today as I was getting ready for a Real Estate shoot, I put batter #1 into the charger, and, nothing. No lights, no indication of charging, nothing. Pushing the on/off button repeatedly did not revive it. It just stood there, silent and dead. I remember looking at the battery's stats on the controller - it was charged 81 times. During its last mission it worked gallantly as we few over an apartment complex, filming for a promo video. Rest easy in chemical heaven, battery #1.
