The content about making a auto cut-off lead acid battery charger circuit. Using this circuit, you can charge your 12v battery automatically.
When your battery became full charge, then charger will automatically off. For your battery will not be over charge.
Since, I don't have lead acid battery charger, for that cause I don't show your changed a battery.
in today's video i have shown how to make a simple automatic battery charger circuit with auto cut-off facility. You can use it for any battery. You have to just set the threshold voltage as per your battery.
Normally the relay is OFF and battery charged but when battery voltage increases to the selected voltage the relay energized by the transistor which now disconnect the battery from the charger thus it prevents from over charging.
Parts list:-
12V relay
BC547 or any transistor
1K resistor
3.3K resistor
Red led (To indicate charge complete)
Green led (To indicate charging)
10K preset
4 diode
1000 uf capacitor
1 Step-down transformer as per your battery voltage
