I have cleaned the contacts thoroughly and yes I have have my roommates eGo charger and it is giving me the same results. When it is unplugged completely, even pressing the button does nothing. (Normally, the button would turn white while holding the button.) And yes, I have hit the button 5 times to "turn the battery on or off."
When the battery is plugged in, the white light just flashes and flashes and the green light on the USB charger stays green. All of this is very new to me, as I have never seen the button just flash over and over again whilst plugged in, but show absolutely no signs of life whilst not plugged in. The only thing I have ever really used on this battery was my Vision ViVi Nova STV and I have never had any of these issues before. It was working only an hour or two ago while I watched the Pittsburgh Penguins get stomped out. Sometime during the game, everything with the battery just stopped firing. I have plugged the STV into an 1100 mah Riva-T VV battery and also a 510 manual battery and that still works perfectly on both of those.
This Spinner battery is practically brand new, but now does not work at all with anything that I have screwed into it; ie. STV, Vision Nanos, 510-T atomizers, etc.
