Haven’t tesearched it, but none of my other 18650’s work in this and I have a variety of them protected an unprotected ect this one that came with the light is longer than them all I believe. An no micro usb on the battery either as was discussed. Dissapointed that it doesn’t feel like it’s compa with my other batteries but otherwise like the light.
DamCamThe ONLY issue I have had with any of my 18650s is a few that are flat tops and dont make contact with the positive lead. I have resolved that issue with a Aluminum spacer (no clue where I got it from TBH) that works without issue. Maybe I got lucky with mine but I carry and use it daily without any issues.
I have even had a few people try to "forget" to return it to me.
DamCamI've taken one of those tiny button magnets that have become readily available, and topped a couple of the buttonless 18650s that I have laying around, and it fits perfectly. The battery pocket on the carrying pouch holds an extra, and I've not had any problems making a connection.
ddornYeah I had to order more of those small magnets for that exact reason. I have a lot of salvaged cells and it seems that somehow a lot of my magnets all mysteriously went on walkabout without their battery friends.
