Recharging a battery involves the conversion of electrical energy to chemical energy. During recharging, there is movement of electrons from an external power source to the anode, and on the other side electrons are removed from the cathode.
A battery charger is basically a DC power supply source. Here a transformer is used to step down the AC mains input voltage to the required level as per the rating of the transformer.
Working Principle of Lead Acid Battery
When the sulfuric acid dissolves, its molecules break up into positive hydrogen ions (2H+) and sulphate negative ions (SO4тАФ) and move freely. Thus, during charging the lead cathode remain as lead, but lead anode gets converted into lead peroxide, chocolate in colour.

Why sugar cane is sweet?
It allows plants to absorb the sun’s energy more readily. In the same way that animals store fat, the sugarcane plant stores energy that is doesn’t need. This extra energy is sugar and it is stored as sweet juice in the plants’ stalks. When ripe, sugarcane stalks are harvested and converted into raw sugar.
Sugarcane is sweet due to presence of high amount of carbohydrates, which are sweet in nature, It contains carbohydrates namely, sucrose, glucose and fructose.
Thus, high amount of glucose and fructose is responsible for sweet flavour of sugarcane.

Lead Acid Battery is a rechargeable battery developed in 1859 by Gaston Plante. The main advantages of Lead battery is it will dissipate very little energy (if energy dissipation is less it can work for long time with high efficiency).
