I don't know why my batteries aren't charging! I recently bought a tesla mod and it came with two Dishy 3.7v 2200MaH batteries and a single cell charger and when the batteries read 3.4v I put one in the charger and the red light became green and not blinking, if I put it in the opposite way it goes brighter red, I left it in the charger when it was green light for 6 hours and the voltage didn't go up! Ugh!

**UPDATE**

I just bought a trustfire charger and it works marvellously.
