Car Battery Charger
This charger will rapidly and effectively charge most any lead corrosive battery. The charger conveys full current until the current drawn by the battery tumbles to 150 Mama. As of now, a lower voltage is connected to complete off and keep from over charging. At the point when the battery is completely charged, the circuit switches off and lights a Drove, letting you know that the cycle has wrapped up.
| R1 | 1 | 500 Ohm 1/4 W Resistor | |
| R2 | 1 | 3K 1/4 W Resistor | |
| R3 | 1 | 1K 1/4 W Resistor | |
| R4 | 1 | 15 Ohm 1/4 W Resistor | |
| R5 | 1 | 230 Ohm 1/4 W Resistor | |
| R6 | 1 | 15K 1/4 W Resistor | |
| R7 | 1 | 0.2 Ohm 10 W Resistor | |
| C1 | 1 | 0.1uF 25V Ceramic Capacitor | |
| C2 | 1 | 1uF 25V Electrolytic Capacitor | |
| C3 | 1 | 1000pF 25V Ceramic Capacitor | |
| D1 | 1 | 1N457 Diode | |
| Q1 | 1 | 2N2905 PNP Transistor | |
| U1 | 1 | LM350 Regulator | |
| U2 | 1 | LM301A Op Amp | |
| S1 | 1 | Normally Open Push Button Switch | |
| MISC | 1 | Wire, Board, Heatsink For U1, Case, Binding Posts or Alligator Clips For Output |
NOTE :
A heatsink will be required for U1.
To utilize the circuit, connect it to a power supply/connect it to. At that point, join the battery to be charged to the yield terminals. All you need to do now is push S1 (the "Begin" switch), and sit tight for the circuit to wrap up.
On the off chance that you need to utilize the charger without needing to give an outside power supply, utilize the accompanying circuit.
