I started out with ego batteries and had to google how they act when charged, or when they need charging, lol. I just couldn't remember. Google didn't tell me anything about flashing after it's plugged in to charge, only beforehand. What I do remember, they got me off cigarettes, but they sure didn't last very long. I think I went through 4 of them before stepping up to different types of devices.
I hope you figure it out, soon, though. And I hope you have a back up device. Very very important.
