How Can I Wire Two 9 Volt Batteries Together?
Hey everyone im making an electric igniter and i installed a momentary push button, toggle switch, and a 12V Direct Current LED. Basically one 9V Battery is not enough power i need at least two! Can some one help me figure this out! I have plenty of wire and Other 9v BATTERY related materials HELP WOULD BE APPRECIATED! ESPECIALLY A DIAGRAM.
You cannot get 12 volts from two 9v batteries in either series or parallel.
If you hook 2 batteries in series to get 18 volts, you could light the LED but you would also need to install a resistor in the circuit that will use 6 volts or the diode will likely burn out..
Better yet, go to radio shack and find a 9v diode and just use one battery.
