Found: an 18650 Li-ion battery at Spider Lake

Hey All, While out snow-shoeing this past Sunday I found an 18650 Li-ion battery near the middle of Inner Peace trail at Spider Lake. If you lost this battery out there recently, please identify the model and case it was found in, and I’ll arrange for you to get it back.

edit Not mine. Thought my spare might have fallen out of my pack when I went to grab my saw last ride.
