I want to charge mobile battery of 3.7 v directly by connecting 2 terminals of charger(5 v output) to two terminals of battery. My questions are
- Is IT POSSIBLE?
- what must be voltage adjusted to charge 3.7 v battery?
- Is there any circuit inside mobile phone charger already that will stop charging, when battery become fully charged?
- Is there any additional circuit required?
- Is there any risk/precaution ?
