In a lead-acid battery the energy is stored in the form of

charged ions
chemical energy
electrostatic energy
electromagnetic energy

The correct answer is: A. charged ions.

A lead-acid battery is a type of secondary battery that uses a lead-acid chemical reaction to store energy. The energy is stored in the form of charged ions, which are able to move between the positive and negative plates of the battery. When the battery is discharged, the ions move from the positive plate to the negative plate, and when the battery is charged, the ions move back to the positive plate.

The other options are incorrect because:

  • Chemical energy is the energy stored in the bonds between atoms. This type of energy is released when the bonds are broken.
  • Electrostatic energy is the energy stored in an electric field. This type of energy is released when the electric field is discharged.
  • Electromagnetic energy is the energy of electromagnetic waves. This type of energy is released when electromagnetic waves are emitted or absorbed.
