12Vdc mobile battery charger circuit diagram can delivers up to 20 V output from the 12V car power supply, allowing a constant current charging […]

This is a car nicd battery charger circuit that can charge any Ni-Cd battery between 4.8 and 4.4 volts from a classic 12 Volts car battery. The charging current is constant it can be selected from the values ​​of 50 to 120 mA by the selector S.

The solar battery charger circuit is nothing but a dual comparator that connects the solar panel to the battery when the voltage at the latter terminal is low and disconnected if exceeding a certain threshold. Since it is only by measuring the battery voltage, it […]

Description of the 12V battery charger electronic scheme : Below is a very simple circuit that can be used to charge 12v car battery. In this circuit there is installations to control the charging current and voltage. The circuit is based on the circuit MC78T12ABT IC from […]

This high performance battery charger circuit allow quickly charges gelled lead-acid batteries, and automatically turns off at full charge. First, the charge current is […]

This mobile battery charger is designed primarily in order to give model enthusiasts the opportunity of charging their Nicad batteries from a car battery […]

This Lithium battery charger circuit is dedicated to charge lithium batteries. It uses 2 chips, voltage regulator LM317T and ICL7665 warns microprocessors (μPs) of overvoltage and undervoltage conditions.
