Got the BR-1206W (the green one). At first the light stayed green and gave off a faint buzzing sound when I had a drained batt in it. Then I flipped the switch to 4.7 (I think) and the light turned red, then after a while started flashing and turning a kind of orange color. It turned back to green after a while, and the batt appears to be charged. Wondering if anyone else has this charger and if this sounds normal. Charging cr-123s and 14500s both 3.7v.
