Donning my Sherlock Holmes hat, my guess is that the previous owner of the Mavic Pro that you recently bought used, may have stored the drone for several months, or maybe even several years, without any use , or battery charge cycles. I experienced something similar when I bought a Phantom 3 Standard brand new, way back in 2016, but only got around to using it in 2020, by which time BOTH brand new batteries would not power up, and no longer showed any sign of life when the battery button was pressed.
I had buried both of those dead batteries with full military honors and ordered new non-OEM batteries, before I learnt in a discussion forum that it is in fact possible to "revive" a clinically dead drone battery. Given the enormous explosive potential of these lipo batteries though, I would still opt to dispose of a dead battery, than try my hand at any surgical procedure that carries the risk of blowing up in my face. |
