Circuit to charge a battery
WebIf adapter is rated 3.7V 300mA, it does not mean it will limit current to 300 mA. It means at >300mA it will overload, overheat, and output voltage will drop. So possibly it will charge your battery with 1A and that is bad. Use a serial resistor to limit current. To charge one battery from 3.7V, calculate voltage difference as V = 3.7V-1.5V = 2.2V. WebThis circuit can be used to charge all type of 12V rechargeable batteries including car batteries. The circuit is nothing but a 12V DC power supply with an ammeter for monitoring the charging current. The two diodes …
