---------------------------------------------------------------------------------------

For This Project We Are Going to Need A Few Things
1)12v CAR BATTERY
2)Digital Multimeter
3)Digital Voltmeter
4)Jumper cables(Wires would work but jumpers would be safe)
5) Laptop Charger(10-17v only.)

Now You Need To Follow This Schematic Diagram And Start Charging the Battery
To Be More Safe I Crimped Off The DC jack From The Laptop Charger Though You Can Still Use The Dc Jack As It Is,The Outer Metal surface is negative whereas the Small Hole Inside The Dc Jack Is Positive!
--------------------------------------
The Reason That the positive Wire Is Going through multimeter is because by that it will show us the current reading on multi meter!

Now Our Car Battery Is Charging!
Keep Noting the current and the Voltage!

Now After 4 hours Of Waiting, The Voltage of the battery was near 12.3
I hooked it Up With My Car And Tested It
And YES it started to see the car starting just visit my youtube video embedded in Introduction!
