Fenix TK-21...18650 problem

CRS · Mar 7, 2013

Hey all. I was going to use an extra Orbtronic 3100mAh in an older Fenix TK-21. However, it appears the the + contact on the battery does not make contact inside the flashlight. Do any on you know a workaround for this?....a way to perhaps modify the contact?
Thanks in advance for any advice

A very thin magnet or other spacer. Watch out for s horts to the body or circuit. Flat top batteries are trouble.
