CB Certificated LiPo Batteries

3.7V Rechargeable LiPo Batteries Manufacturer Supplier, CB certificated lithium polymer batteries for your new device.

What is the CB Scheme?

The IEC System for Conformity Assessment Schemes for Electrotechnical Equipment and Components (IECEE) Certification Body (CB) Scheme is the world’s first international system for the mutual acceptance of product safety test reports and certificates for electrical and electronic equipment, devices, and components. Based on the use of internationally-accepted product safety standards, the CB Scheme relies on a global network of CB testing laboratories (CBTLs), who are responsible for testing products to applicable technical standards. Product test results are then submitted to national certification bodies (NCBs) in CB Scheme member countries, who can authorize legal access to CBTL-tested products without additional testing.

The CB Scheme is an international program for the exchange and acceptance of product safety test results among participating laboratories and certification organizations around the world. The CB Scheme offers manufacturers a simplified way of obtaining multiple national safety certifications for their products.

Since May 2012:
– Batteries tested to UL 1642 or UL 2054 will not be accepted
for CB Scheme Certificates
Rechargeable Batteries and cells must be CB Scheme
certified to IEC 62133
– Non-Rechargeable Lithium Batteries and cells must be CB
Scheme certified to IEC 60086-4 (specified in IEC 60601-1)

What are the benefits of the CB Certification Scheme?
Presently, there are more than 50 CB Scheme member countries around the world, including European Union (EU) the Member States, the U.S., China, India, Korea, and Russia. Manufacturers using the CB Scheme can potentially gain access to every CB Scheme member country without the need for expensive, duplicate testing. Further, CB Scheme applicants are often given priority consideration by NCBs since no additional testing is required.

What products are covered under the CB Scheme?
Batteries, cables and cords, capacitors as components, medical equipment, household appliances, installation accessories and connection devices, switches for appliances, automatic controls for electrical household appliances, IT and office equipment, lighting, low voltage and high power switching equipment, portable tools, safety transformers, and similar equipment.

How are national differences handled?
Compliance with national differences may be evaluated either by the NCB issuing the CB Test Certificate and CB Test Report or by the NCB to whom the CB Test Certificate and CB Test Report are presented for recognition and acceptance. However, it may further reduce costs, completion time, sample requirements, and project complexity by having all appropriate national differences evaluated by the NCB who issuing the CB Test Certificate and CB Test Report.

How can I apply for CB Scheme certification?
A manufacturer can apply to any NCB for either a CB Test Certificate or for certification based on an existing CB Test Certificate. The NCB will provide details on fees, samples, documents, and certification procedures applicable in the country of the NCB.

Benzo Energy can help customers to apply for the CB Certification. Each test takes 4-6 weeks after then you will get an official IEC 62133 test report and CB Certificate published by the third-party testing house (TUV).

We perform tests with cells and batteries according to IEC 62133 and can provide you with a CB certificate. The CB-Scheme was initiated by IEC in order to ease approval procedures for products in different countries.

For CB-Certification of products that contain batteries, it can be necessary that these are certified according to IEC 62133.

The standard IEC 62133 distinguishes between Nickel and Lithium-Ion cells and batteries. Depending on the chemistry and type (cell or battery pack) several different tests have to be performed to gain an IEC 62133 CB certificate.

For Lithium-Ion cells and batteries the 62133 contains the following single tests:

8.1.2 Charge
8.2.1 Continuous charge
8.2.2 Moulded case stress
8.3.1 External short circuit
8.3.2 External short circuit
8.3.3 Freefall
8.3.4 Thermal abuse
8.3.5 Crush
8.3.6 Overcharge
8.3.7 Forced Discharge
8.3.8 Transport
8.3.9 Forced Internal Short

Caution!  – LiPo Batteries

In order to prevent the LiPo Battery from possibly occurring leaks, overheating, swollen, please note the preventive measure.

Handling Precautions and Guideline:


When charge please select the LiPo Battery special battery charger.


Strictly prohibits inverting the cathode use LiPo Battery.


Strictly prohibits directly connecting LiPo Battery to power source plug


Please do not throw the LiPo Battery into water or put it into the heater


Strictly prohibits plunging the LiPo Battery in seawater or water, when LiPo Battery does not use, please store LiPo Battery in a cool dry environment.


The prohibition in strong static electricity and strong magnetic field place use otherwise is easy to destroy the LiPo Battery PCBA


The prohibition puts the LiPo Battery nearby the hot high-temperature source, like the fire, the heater, and so on use and leaves alone


The prohibition directly connects the LiPo Battery cathode with the metal to short-circuit.


The prohibition rap or throws, steps on the LiPo Battery and soon


Forbids directly to weld the LiPo Battery and pierces the LiPo Battery with the nail or other sharp weapons


If the LiPo Battery sends out an unusual smell, gives off heat, the distortion or appears any exceptionally, immediately moves the LiPo Battery from the installment or the LiPo Battery charger to and stops using


If the LiPo Battery occurs leaks, the electrolyte enters the eye, please do not have to rub scratches, the application clear water flushing eye and delivers the medical treatment otherwise to be able immediately to injure the eye


When LiPo Battery long-term storage, or assembly in the host, suggest customer should take every 6months carry on one-time charge and discharge and recharge it to half charged state (3.7-3.9V)(the method: 0.2CmA charge and discharge)


Abandon the LiPo Battery to wrap up the electrode using the insulating paper, prevented the LiPo Battery from short-circuits


Do not decompose the LiPo Battery


Keep small LiPo cells and LiPo Batteries which are considered swallowable out of the reach of children


Swallowing may lead to burns, perforation of soft tissue, and death. Severe burns can occur within 2 h of ingestion


In case of ingestion of a LiPo cell or LiPo Battery, seek medical assistance promptly.
