What is EN62133 Certification?

en62133 is a safety testing standard for battery products issued by the European Union. However, it cannot be used to issue a ce certificate. Many third-party agencies still issue CE certificates based on EN62133, which is highly unprofessional. (If any laboratory tells you that CE can be issued based on EN62133, it's best not to work with them.) This is because EN62133 is not under the scope of CE directives. It can only be used to issue a TUV-mark certificate and test report.

If a client needs a cb certificate, it should be issued under IEC62133. The test requirements for EN and IEC standards are the same; the only difference is that IEC standards are issued by the International Electrotechnical Commission, while EN standards are issued by the European Committee for Standardization.

IEC62133:2017 Edition Official Release

On February 7, 2017, the International Electrotechnical Commission (IECEE) officially released the updated safety standards for single cells and battery packs with alkaline or non-acid electrolytes used in portable electronic devices:

- IEC62133-1:2017 (Nickel systems)

- IEC62133-2:2017 (Lithium systems)

These replaced the 2012 version of IEC62133 and introduced significant updates. The new standard split IEC62133:2012 into two separate documents based on chemistry type.

Key updates include:

- Button cells are now included

- Clause 5.6 updates on cell-to-battery assembly

- New mechanical tests: Vibration and Shock (7.3.8.1, 7.3.8.2)

- Reference to IEC TR62914 added

Key Differences Between IEC62133:2012 and IEC62133-2:2017 (Lithium Batteries)

1. Standard split:

 - Nickel-based: IEC62133-1:2017

 - Lithium-based: IEC62133-2:2017

2. Button cells are now included in the lithium battery standard.

3. Preconditioning:

 - Old: Cells and batteries conditioned under high/low temperatures.

 - New: Only cells need preconditioning per manufacturer’s charging method.

4. External short circuit test:

 - Old: Cells at 20±5°C, Batteries at 55±5°C

 - New: Cells at 55±5°C, Batteries at 20±5°C

5. Thermal abuse test:

 - Old: 130±2°C, 10 min (large cells 30 min)

 - New: 130±2°C, 30 min

6. Crush test:

 - Old: 13±1 kN, several termination conditions

 - New: 13±0.78 kN, fewer termination criteria

7. Overcharge test:

 - Old: 2C charging up to 5×n (n = series count)

 - New:

 - Single cells: up to 1.4×max voltage (≤6V)

 - Multiple cells: up to 1.2×max voltage × n

8. Forced discharge:

 - Old: Reverse charging at 1C for 90 mins

 - New: Reverse charging to -1×max charge voltage for 90 mins

9. Transport testing:

 - Old: Full IEC62281 transport tests

 - New: Vibration and mechanical shock only

10. New AC internal resistance test for button cells

Labeling Requirements for IEC/EN62133

2. Model designation

3. Polarity

4. Manufacturing date

5. Manufacturer or supplier’s name/trademark

6. Rated capacity

7. Nominal voltage

8. Watt-hour rating
