３ circles
Today's 1X photo.
Two white circles surround the silver circle.
It must be some kind of part.
Or a curling stone.
Is the silver part iron or stainless steel? The surface is surprisingly rough.
Here's a 1X photo.
It's a rechargeable AA battery.
thank you always.
The problem is that there is no way to know when the battery is old and has lost its functionality.
However, cheap and sufficient functions, batteries are amazing technology.
Shooting as usual.
