  • Single T, could you please help?
    I’m using the charger to charge a new 900mAh 3.7V battery. Well when I connect the battery the “status” light doesn’t come on. After an hour, I measure the voltage of the battery and it’s still at 0.05V. It doesn’t seem to work…what could be the problem?

No public wish lists :(
