I have a new EDC15 and a slightly older Tool 2.0 and normally use them with NIMH batteries. I decided to pop an old UltraFire 14500 in them to test. On one occasion with both lights, they were stuck on one of the higher levels and did not cycle through the steps until I removed the cell for a minute or so. Never had this happen on NIMH or Alkaline cells. Anyone have this happen?
