8.Product procedure:

1	Zinc can	The zinc can is the negative terminal and anode material
2	Inserting the separator	The separator and the bottom paper are inserted to prevent battery short-circuit between the positive and the negative electrode.
3	Filling cathode material	The mixture of manganese dioxide, electrolyte and others are filled as the cathode material
4	Inserting carbon rod	The carbon rod for collecting electricity is inserted into the middle of the battery
5	Sealing	The plastic gasket for sealing is fitted to prevent leakage and water evaporation
6	Fitting tinplate bottom and PVC jacket	The tinplate bottom is placed on the bottom of zinc can and PVC jacket is shrinked
7	Finished product	The batteries are packed by shrink after inspecting the voltage, current and appearance
