Secondary cells and batteries

What are Secondary cells and batteries?

In Common Words those batteries are rechargeable are known as secondary batteries.Secondary batteries & Cells are the rechargeable. They have the advantage of being more cost-efficient over the long term.

Applications Secondary cells and batteries:


Power tools

Motor drives

Laptop computers

Mobile phones

For the safe operation or safety purposes IEC ( International Electrotechnical Commission) Introduce the IEC 62133 ( for more info visit our website ( ) the standard for Secondary cells and batteries containing alkaline or other non-acid electrolytes.  This standard covers rechargeable Nickel cells and batteries, as well as lithium ion (Li-Ion) cells and batteries.

About the IEC 62133 Standard

IEC 62133 is the most important standard for exporting Lithium-Ion batteries, including those used in IT equipment, tools, laboratory, household and medical equipment.
