If I remember correctly, and if I’m incorrect, hopefully someone will fix that, if you push the power button on one that’s in hibernation mode, no lights would appear.
It exits hibernation mode the first time it’s charged.
Again, let’s wait on...
Guessing the answer is no but is there a way to tell if a battery is in hibernation mode without activating? I recently bought an open box Mavic 3 battery from camrise. Mine had zero cycles on it so it was probably in hibernation until I put it...
It covers everything except the bottom rear sensor. So not completely, I guess, but it's still pretty decent coverage without needing to rig up anything extra.
