Why is an auto shut off battery charger needed? The main reason to get an auto shut off battery charger is to protect the battery from overcharging and consequently reducing its useful life. Can a car battery be overcharged? Yes, you can overcharge a car battery. Car batteries take whatever voltage is sent to them, regardless of whether […]
12V Auto Turn-off Battery Charger
This 12V Auto Turn-off Battery Charger with current limiter, uses only 4 transistors, will stop charging the battery when it has 14 volts between its terminals and limits the charging current to a maximum of 2 amps.
12V Auto turn-off battery charger
This 12V auto turn-off battery charger automatically disconnects from mains to stop charging when the batteries are fully charged. It serves to charge the battery of our car, using the 120/240 VAC
Car Battery Monitor Circuit
This Car battery monitor circuit is very simple and very interesting. How many times have you found that the car does not start because the battery is discharged?
Car battery monitor circuit using 4 LEDs
This simple Car battery monitor, allow us to know the voltage of the battery at all times. To achieve this 4 leds are placed somewhere on the dash of the car. Each LED has a label indicating the battery voltage at that time.
