on video Auto cut off 12v Battery charger circuit using Relay, Simple 12 volt Battery Charger

 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

We prepared this circuit for you,
