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.
