what is the cell reaction of dry cell?

Dear student,

The dry cell battery is one of the most commonly used types of batteries. A, C, 9-volt, and watch batteries are dry cell batteries. Invented by Sakizou Yai in 1885, the dry cell battery was improved and patented by Dr. Carl Gassner, a German scientist in 1887. A dry cell battery is different from a wet cell battery because its electrolytes are contained in a low-moisture paste. A wet cell battery's electrolytes are contained in a liquid. Wet cell batteries are often used in cars because they are relatively cheap and easily recharged.
