General dry cell is to utilize zinc metal sheet and inner sal-ammoniac generation chemical reaction, make it to form zinc chloride, ammonia and hydrogen, and battery in use, be battery discharge procedure, during battery discharge, on negative pole, carry out oxidation reaction, electronics outwards then is provided, carry out reduction reaction on positive pole, accept electronics from external circuit, electric current flows to negative pole through external circuit from positive pole;

Because inner electrolyte is an ion conductor, the orientation of ion between the both positive and negative polarity of inside battery moves and conducts electricity, cation flows to anodal, anion flows to negative pole, so entire cell has formed a complete discharge system that is made of the ionic system of the electron system of external circuit and electrolyte solution, and then makes it to produce electric energy;

And after powered battery has been used of a specified duration, its outer field zinc metal sheet can become more and more thin, and the carbon-point outer rim at center is then surrounded by ammonia and the hydrogen that reaction generates, so can't continue to make it to produce reaction, because it has consumed the material in the battery, so can't use repeatedly.

In addition, the open circuit voltage of zinc-manganese dioxide dry cell can be because the length in storage time, and the different in kind (electrolytic manganese dioxide, natural manganese dioxide etc. are arranged) of negative electrode manganese dioxide and changing, and the general boundary of scope is between 1.5V～1.8V;

So, these battery limited are in open circuit (startup) the voltage difference of electrical appliance, and can't start the time, in fact, battery still has the surplus chemical reactant, if be used in the electrical appliance of low-voltage, still can use, for example clock, remote controller etc., its cut-ff voltage is below the 0.5V, yet ordinary consumer is thought can't start electrical appliance, just abandoning with being about to it, is quite waste and not environmental protection in fact; Therefore, require further improvement.。
