Difference between primary cell and secondary cell

1. 

Primary cells are a type of batteries which are not easily recharged after use. Secondary cells are also a type of battery which is easily charge after use. Which means it is rechargeable.

It is discarded after a single use, But secondary cells are used over and over again. By recharge of battery.

2.  It is not disposable

It is disposable

3. Primary cells example, boys, toys, radio cell, and watch cells etc. which are use only one time. Simply we say that use and threw.  

Secondary cells example, automobile field battery, power source battery, power pack etc. which is recharge again and again according to requirement.

  4.  It is usually lack a free-flowing electrolyte; instead, they hold the electrolyte inside solid devices which called separators. Because they lack a significant quantity of liquid electrolyte, such batteries are often called dry cells..

When secondary cells have completely discharged then they can be recharged and used again. By pumping electric current through the cell in the opposite direction that it normally flows, for additional use cell can recharge.

5.   Primary cells life-cycle cost is low.

Secondary cells life-cycle cost is high than primary cells.   it is main difference between primary cell and secondary cell.

6. Primary cells initial cost is lower because it is use only one time .

Secondary cells initial cost is higher than primary cell. Because it is rechargeable.

7. Replacement readily available.

 In this type of cells , Replacements are not available .

8.  It is both type lighter and smaller thus traditionally more suitable for portable application. And longer service per charge and good.

Secondary cell is Traditionally less suited for portable applications, although recent advances in Lithium battery technology have led to the development of smaller/lighter secondary batteries.

It main difference between primary cell and secondary cell.

9. It is not suitable for high load and longer service.

secondary cell are suitable for heavy load and longer service
