The storage battery or secondary battery is such a battery where electrical energy can be stored as chemical energy and this chemical energy is then converted to electrical energy as and when required. The conversion of electrical energy into chemical energy by applying external electrical source is known as charging of the battery. Whereas conversion of chemical energy into electrical energy for supplying the external load is known as discharging of the secondary battery.

During charging of the battery, current is passed through it which causes some chemical changes inside the battery. This chemical changes absorb energy during their formation.

When the battery is connected to the external load, the chemical changes take place in the reverse direction, during which the absorbed energy is released as electrical energy and supplied to the load.

Now we will try to understand the principle working of leadacid battery and for that, we will first discuss about leadacid battery which is very commonly used as storage battery or secondary battery.
