I usually power my Tool AA 2.0 with a NIMH battery without any issue. Just bought an EDC15 and put an unprotected 14500 in it. While playing with it, it got stuck on a high level. Had to remove the cell for a minute or two and it started working properly. Put that cell in the Tool AA and eventually it got โstuckโ on a higher level for several click cycles. Put the NIMH back in and it has worked fine since.
I have not managed to repeat this with the cell so I donโt know if the rate I was cycling the levels had anything to do with it or not. Anybody have similar experiences with either of these lights? It was weird.
