| help me about my research in charging
friends today i tried to do research about china charging circuit. i took two or three well working chinese sets . after inserting charger i measure voltage on battery connector , it is showing app. 1.3 v. i am confused because i thought that well working set should have to provide app. 3.7v on battery connector.
how can a battery is charging well on 1.3v.
if anyone knows about this plz help
thanks in advance |
