Introduction: 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.
Step 1: Circuit
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!
Step 2: Print
We prepared this circuit for you,
you can download it from the link below
then print it by any printer,
and use any prototyping electronic circuit after that stick the paper to the board,
Step 3: Video
you can see this video and make step by step with this video
We have a be nice policy.
Please be positive and constructive.
is it applicable to any kind of power source, eg. solar charger or alternator?
Ok. Porém os LED'S não estão invertidos no circuito?
Okay. But the LED's are not inverted in the circuit?
