I've had a Blu starter pack lying around my house for a while now and just recently decided to open it and test it out. Both the batteries worked for a little while before needing recharging, so I charged one in that portable recharger pack overnight. The bottom light was red briefly then turned off but I assumed it was charging, but the battery still didn't work even after like 8 hours of being in the recharger pack. Tried the same thing with the other battery, same result. I have the charging pack plugged in and the blue light is on but both batteries have the red light on for a few seconds, then blink red a few times and turn off. I don't know what this means, am I doing something wrong or did I just get screwed with two bad batteries?
