Electrical Batteries
Definition
Electrical batteries are devices that store and release electrical energy through chemical reactions. They consist of one or more electrochemical cells, which convert chemical energy into electrical energy.
Analogy
Think of an electrical battery like a rechargeable water bottle. When you fill it up with water (charge the battery), you can use it to quench your thirst (power your devices). Once the water runs out (battery is discharged), you need to refill it again to keep using it.
