Step 3: Wrap the Aluminium Foil
Wrap the aluminium foil around the rod such that there is no direct connection between the graphite rod and the aluminium foil
Step 4: Test the Continuity Between the Rod and Outer Foil
It's is much important to check the continuity between rod and outer foil so there would be no continuity between the rod and outer foil.
Step 5: Dissolve the Cell
Dissolve the rod/cell into the acidic solution/vinegar or rain water and this sol will act as a electrolyte.
Step 6: Your Battery Is Ready
Remove the battery from the solution. And check the voltage around it with the help of a multimeter and is your choice to connect it in series with more similar battery to increase the net voltage.
