What is the Marking Method for Rechargeable Batteries Specified by IEC?

The International Electrotechnical Commission (IEC) specifies a marking method for rechargeable batteries through a set of standards. The marking method typically includes information about the battery's characteristics, specifications, and safety requirements. 

IEC standards are subject to updates and revisions. For example, there is the IEC standard for marking rechargeable batteries is IEC 61960. 

The IEC 61960 standard defines a system for marking secondary (rechargeable) batteries. The marking typically includes:

Manufacturer's name or logo

Battery model or type designation

Nominal voltage of the battery

Capacity, which can be expressed in ampere-hours (Ah) or milliampere-hours (mAh)

Chemical symbol for the battery's chemistry, such as "Li-ion" for lithium-ion batteries

Operating temperature range

Date of manufacture or a batch code

Safety information and compliance with relevant safety standards

There is also the marking method for rechargeable batteries specified by IEC 61851-1:2011. It is a pictogram, which shows the type of the battery. The label can be divided into two parts:

3.2V 20A Low Temp LiFePO4 Battery Cell -40℃ 3C discharge capacity≥70% Charging temperature：-20~45℃ Discharging temperature: -40~+55℃ pass acupuncture test -40℃ maximum discharge rate：3C

- The first part shows the following information:

1) Type of battery (rechargeable, primary batteries etc). This part is illustrated by a pictogram.

2) Name of manufacturer (nameplate). This part is illustrated by two rectangles that are placed on top of each other.

3) Date of production (year and month). This part is illustrated by a rectangle with two lines crossing through it.

4) Total discharge capacity of battery. This part is illustrated by two rectangles pointing upwards and downwards towards each other with a dot in between them.

The marking method for rechargeable batteries specified by IEC is as follows:

The marking shall be applied to the battery by means of a label, a band, or other means.

The mark shall be applied in such a way that it can be seen without any difficulty by the user and without any damage to the battery or its container.

The mark shall be as large as possible and legible with regard to shape, colour, font and size.

Low Temperature High Energy Density Rugged Laptop Polymer Battery Battery specification: 11.1V 7800mAh -40℃ 0.2C discharge capacity ≥80% Dustproof, resistance to dropping, anti - corrosion, anti - electromagnetic interference

What is the IEC code for batteries?

The International Electrotechnical Commission (IEC) does not assign specific codes for batteries. The IEC is an international standards organization that develops and publishes standards related to electrical and electronic technologies. It provides standards for various electrical and electronic components, systems, and equipment, including batteries.

However, the classification and labeling of batteries are typically governed by different standards organizations and regulations. For example, batteries may be classified and labeled according to standards set by organizations like the United Nations (UN) for transportation and safety purposes. These standards include UN numbers and codes for various types of batteries to indicate their characteristics and hazards.

Also, IEC codes are typically not used to identify specific types of batteries. Instead, batteries are often classified and identified by other standards and codes specific to their chemistry, size, and application.

For example, batteries can be classified by chemistry, such as:

Alkaline Batteries

These are commonly identified by their size (e.g., AA, AAA, C, D) and may have an ANSI/NEDA designation.

Lithium-ion Batteries

These are typically identified by their voltage and capacity ratings.

Lead-acid Batteries

These are often classified by their size (e.g., automotive, motorcycle, or deep-cycle batteries) and may follow various industry standards.

Nickel-metal Hydride (nimh) Batteries

These are also usually identified by their size and capacity.

Lithium Polymer (LiPo) Batteries

These are often identified by their voltage and capacity ratings.

What is the IEC in battery testing?

The IEC, or International Electrotechnical Commission, is a global organization that develops and publishes international standards for a wide range of electrical and electronic technologies. In the context of battery testing, the IEC has established standards that define various aspects of battery performance and safety testing. These standards are important for ensuring that batteries meet certain quality and safety criteria.

IEC battery testing standards cover a variety of parameters, including:

Capacity Testing

These standards specify how to determine the capacity of a battery. This is important for understanding how much energy a battery can store and deliver.

Cycle Life Testing

Cycle life testing assesses how many charge and discharge cycles a battery can go through before its performance significantly degrades.

Performance Testing

Performance testing standards may cover parameters like voltage, current, and discharge characteristics under different conditions, including temperature and load.

Safety Testing

Battery safety standards are critical for ensuring that batteries are not prone to hazards like overheating, short-circuiting, or leaking. These standards may involve various safety tests, including thermal stability, crush tests, and overcharge tests.

Environmental Testing

This includes standards for evaluating a battery's performance under various environmental conditions, such as high and low temperatures, humidity, and vibration.

Transportation Testing

These standards address the safety of transporting batteries, ensuring they do not pose risks during shipping.

Labeling and Marking

Standards for battery labeling and marking help in identifying the type of battery, its specifications, and any safety warnings.

These IEC standards are used by manufacturers, regulatory agencies, and testing laboratories to ensure that batteries meet specific performance and safety requirements. Compliance with these standards is important for consumer safety and for the reliability of products that use batteries, ranging from consumer electronics to electric vehicles.

IEC standards typically have a unique code, such as IEC 62133 for rechargeable lithium-ion batteries. It's essential for battery manufacturers and users to be aware of and adhere to relevant IEC standards to ensure the quality and safety of batteries in various applications.

What is the IEC standard for lithium-ion batteries?
