This morning I found out that my replacement battery was left in the rain over the night.
It is for GoPro 7 Hero Black.
Is it still safe to use? Would it work? I have not put it into the camera yet. I would like to know what you suggest first.
Try to check the contact points of the battery and see if there are signs of corrosion.
If there's none, you may have it tested with the camera.
Please make sure that it is all dried up before testing.
Let us know how it goes.
