Video Explanation

Answer 2

The cell which is not primary among the following is the lead accumulator cell.

Detailed answer

As we know a primary cell is a cell that produces current or electricity through an irreversible reaction so there is no turning back.

• This is what we call a use-and-throw battery as it is non-rechargeable.
• The Lead accumulator cell is a secondary cell as the energy is already stored in an external source. They are rechargeable and can be used again and again.
• The energy is stored in the form of chemical energy.
• It uses sulphuric acid as its electrolyte so it is highly corrosive and dangerous.
• All the others are examples of primary cells.
