Diy cell batteries

Such a galvanic cell produces roughly 1.5 volt which is why it is necessaiy to insert several diy cell batteries in series to achieve sufficient voltage to run a pocket calculator. The figure below shows the principle of the set-up of such an acid dry cell battery. 

In respect to the acid diy cell battery the life time for the alkaline batteiy is significantly longer as zinc corrodes slower in basic than in an acid environment.
