Why do they lose energy when they are not used for a long time? Well I tried my best to find the best answers for these questions and a little more.
Battery, also called an electric cell, is a device that converts chemical energy into electricity. All batteries contain an electrolyte, a positive electrode, and a negative electrode.

called the dry cell or flashlight battery. The Lechlanche cell is very similar to the dry cell we use today. The positive pole is a rode of carbon embedded in a black manganese dioxide (MnO2) and Carbon particles and the negative electrode is made of zinc. The electrolyte consists of a mixture of ammonium chloride and zinc chloride made into a paste. This sits in between the negative and positive electrodes, which acts as an ionic conductor. When the cell is in use, atoms of the Zinc in the outer case are oxidized, giving up electrons and forming zinc ions.
The electrons are lost by the zinc atoms then flow through the load (the device being powered) and supply energy. They re-enter the cell at the carbon rode that serves as the positive electrode. As this series of events happen, the battery begins to lose pure zinc atoms, and the battery starts to die. This type of cell gives about 1.5 volts of energy. By connecting many cells in a series a rather high voltage can be produced. ...
