	Method
	1.	Test the voltage and connect leads to the C-cell battery.
	2.	Disconnect the leads from the battery and connect them to the leads.
	3.	Place the electrodes at the 50ml mark in beaker of sulfuric acid, 3 cm apart from each other.
	4.	Hold the electrodes in the acid for 3 seconds.
	5.	Record voltage reading on the voltage meter.
	6.	Remove the electrodes and clean oxidization with steel wool. 
	7.	Repeat steps #1-#7 3 times.
	8.	After 3 tests leave the zinc electrode and remove the other and replace with another electrode.
