Difference Between Primary Cell and Secondary Cell
|Primary Cell||Secondary Cell|
|Have high energy density and slow in discharge and easy to use||They are smaller energy density|
|There are no fluids in the cells hence it is also called as dry cells||There are made up of wet cells (flooded and liquid cells) and molten salt (liquid cells with different composition)|
|It has high internal resistance||It has low internal resistance|
|It has an irreversible chemical reaction||It has a reversible chemical reaction|
|Its design is smaller and lighter||Its design is more complex and heavier|
|Its initial cost is cheap||Its initial cost is high|
