on video How To Make Simplest 12v Automatic Cut-Off Battery Charger, or 12 Volt Battery Charger Circuit.


 How to make simplest 12v automatic cut off battery charger at home. Basic auto cut or full charge circuit. Battery charger circuit. 14V cut off battery charger circuit for 12v battery. Basic automatic battery charger. Battery full charge indicator for 12 volt battery.12v automatic battery charger circuit.

12v Automatic Charger (Auto Cut OFF)

what is auto cut off battery charger?


some off charger maybe can't stop charging when the battery is fully charged.

so we want to show you a simple circuit for the charger when the battery is fully charged, the charging automatically stopping,


this is a circuit of the auto cut off battery charger, it has only:-

- one NPN transistor such as c1815 for controlling the charging,

- relay for cutting off this current path through the battery after fully charged,

- 10 kilo-ohm variable resistor connected to the base of the transistor,

the variable resistor used for restricting the voltage from how many volts you want to stop charging!
