With the continued popularity of the consumer electronics market, the lithium battery market has developed rapidly. Not only has its application scope and quantity continued to expand, but the energy of a single battery has also become higher and higher. The continuous lithium battery safety accidents have also made people pay more and more attention to the safety of lithium batteries.

Therefore, a series of certification standards have been formulated around the world to address battery safety issues. So what are the battery certifications?

China Certification

3C Certification (CCC): The full name is the compulsory product certification system. It is a product conformity assessment system implemented by the Chinese government in accordance with laws and regulations to protect consumer personal safety and national security, strengthen product quality management, and implement laws and regulations. If you don’t pass 3C, you can’t circulate in the Chinese market.

International Organization for Standardization Certification

ISO9001: ISO9001 does not refer to a standard, but a general term for a class of standards. It is all international standards formulated by TC176 (TC176 refers to the Technical Committee for Quality Management Systems). It is the best-selling and most common product among more than 12,000 ISO standards. ISO9001 quality assurance system is the foundation of enterprise development and growth.

ISO14001: Environmental management system certification refers to the assessment of the environmental management system of the supplier (producer) by a third-party notary agency based on the publicly released environmental management system standards (ISO14000 environmental management series standards). The qualified ones will be issued with an environmental management system certification by a third-party agency, and registered and announced to prove that the supplier has the environmental assurance ability to provide products or services in accordance with the established environmental protection standards and regulations. Through environmental management system certification, it can be confirmed whether the raw materials, production processes, processing methods used by the manufacturer, and the use and post-use disposal of the products meet the requirements of environmental protection standards and regulations.

Transport certification

UN38.3: UN38.3 refers to Part 3, Section 38.3 of the “United Nations Manual of Tests and Criteria for the Transport of Dangerous Goods” specially formulated by the United Nations for the transportation of dangerous goods. That is, before the transportation of lithium batteries, they must pass high-altitude simulation, high and low temperature cycles, vibration tests, impact tests, 55°C external short circuits, impact tests, overcharge tests, and forced discharge tests to ensure the safety of lithium battery transportation. If the lithium battery is not installed with the equipment, and each package contains more than 24 battery cells or 12 batteries, it must also pass a 1.2-meter free fall test.

MSDS: MSDS is a comprehensive legal document on the characteristics of chemicals provided to customers by chemical production or sales companies in accordance with legal requirements. It provides sixteen items such as the physical and chemical parameters of chemicals, flammability and explosion performance, health hazards, safe use and storage, leakage disposal, first aid measures, and relevant laws and regulations. MSDS can be compiled by the manufacturer in accordance with relevant rules. However, in order to ensure the accuracy and standardization of the report, you can apply to a professional organization for compilation.

EU Certification

CE Certification: It is limited to the basic safety requirements that the product does not endanger the safety of humans, animals and goods, rather than general quality requirements. The coordination directive only stipulates the main requirements, and the general directive requirements are standard tasks. Therefore, the accurate meaning is: the CE mark is a safety certification mark rather than a quality certification mark. It is the “main requirement” that constitutes the core of the European directive. The “CE” mark is a safety certification mark and is regarded as a passport for manufacturers to open and enter the European market.

In the EU market, the “CE” mark is a mandatory certification mark. Whether it is a product produced by an enterprise within the EU or a product produced in other countries, if it wants to circulate freely in the EU market, it must be affixed with the “CE” mark to indicate that the product meets the basic requirements of the EU’s “New Approach to Technical Harmonization and Standardization” directive. This is a mandatory requirement for products imposed by EU law.

RoHS certification: RoHS is a mandatory standard established by EU legislation. Its full name is “Restriction of Hazardous Substances”. This standard has been officially implemented on July 1, 2006. It is mainly used to regulate the materials and process standards of electronic and electrical products to make them more conducive to human health and environmental protection. The purpose of this standard is to eliminate a total of 6 substances, including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers, in electrical and electronic products, and focuses on stipulating that the cadmium content cannot exceed 0.01%.

US certification

FCC certification: It is a standard certification established by more than 50 states, Columbia and the United States to ensure the safety of radio and wired communication products related to life and property. The FCC’s Office of Engineering and Technology is responsible for the technical support of the committee and is also responsible for equipment approval. Many radio application products, communication products and digital products require FCC approval to enter the US market. The FCC committee investigates and studies each stage of product safety to find the best way to solve the problem. At the same time, the FCC also includes the inspection of radio devices, aircraft, etc.

UL certification: UL certification is a non-mandatory certification in the United States. It is mainly for the inspection and certification of product safety performance. Its certification scope does not include the EMC (electromagnetic compatibility) characteristics of the product. It is mainly engaged in product safety certification and business safety certification business. Its ultimate goal is to provide the market with goods with a considerable safety level and contribute to the guarantee of personal health and property safety. As an effective means of eliminating technical barriers to international trade, UL also plays an active role in promoting the development of international trade.

Japan Certification

PSE certification: PSE certification is a mandatory safety certification in Japan, which is used to prove that electrical and electronic products have passed the safety standard test of Japan’s Electrical and Material Safety Law (DENAN Law) or international IEC standards. Japan’s DENTORL Law (Electrical Devices and Materials Control Law) stipulates that 498 products must pass safety certification to enter the Japanese market. Among them, 165 Class A products should obtain the diamond-shaped PSE mark, and 333 Class B products should obtain the circular PSE mark.

Korean Certification

KC Certification: In order to enable consumers to more clearly understand the certification marks marked on the products they purchase and reduce the various certification fees borne by product manufacturers, the Korea Institute of Technology and Standards (KATS) announced on August 20, 2008 that it will implement a new certification system KC) certification on January 1, 2009.

Theoretical introduction to the naming of button battery models and specifications:

1. CR button battery models: Commonly used are CR2016, CR2032, and CR2025, where CR indicates lithium manganese dioxide battery, and the last four digits indicate the size. For example, CR2032 refers to a 3V button battery with a diameter of 20mm and a height of 3.2mm.
2. Zinc-silver oxide battery: The size of the silver oxide battery can be made the same as that of the alkaline zinc-manganese button battery, but the zinc-silver oxide battery has a relatively higher voltage platform and a more stable working voltage. Its naming method is basically the same as the LR series, such as “SR44” for zinc-silver oxide battery, which is the size of both LR44 and AG13. At first, AG13 referred to SR44, but now it sometimes refers to LR44 and sometimes to SR44. Because zinc-silver oxide batteries are more expensive than alkaline zinc-manganese batteries, the latter have replaced part of the former’s market.
3. AG series button battery models: AG batteries are essentially alkaline zinc-manganese batteries, with 14 product series from AG0 to AG13, but in the IEC standard, they are still marked in the same way as alkaline batteries, with the letters “LR”, where L stands for alkaline and R stands for round.

The Japanese standard is marked as “L” followed by three or four digits. If it is followed by three digits, the first digit represents the diameter (mm) in integers; if it is followed by four digits, the first two digits represent the diameter (mm) in integers; the last two digits are 1/10 of the height (mm).

For example, the IEC logo of the AG13 button battery is LR44, and the Japanese logo is L1154. Because the design diameter of this battery is 11.6mm and the height is 5.4mm, the diameter is taken as an integer “11”, and 1/10 of “54” represents the height of 5.4mm.

4. In the button battery family, there are also zinc-air batteries and mercury batteries (also called mercury batteries). Rechargeable batteries also have LIR, ML, and LV series. These button battery models are just different battery systems represented by English, and the size is also represented by four digits. For example, LIR3032 represents a lithium-ion battery with a working voltage of 3.6V, a diameter of 20mm, and a height of 3.2mm. ML2032 and LV2032 represent the same battery size, but they represent lithium manganese batteries and lithium vanadium batteries respectively.

The most commonly used CR series in our daily life is manganese dioxide battery. Do you understand it?

1. Correct classification and recycling

Correct classification and recycling is the basic method for handling harmful substances in batteries. At present, many places have set up battery recycling stations, through which batteries can be recycled. The recycled batteries will be reprocessed and treated by professional organizations to avoid the pollution of harmful substances to the environment. Therefore, battery recycling should be taken seriously, and waste batteries should be uniformly placed in recycling stations to protect the environment.

2. Correct storage of batteries

Correct storage methods can also reduce the harm of harmful substances in batteries to the environment. Many people are accustomed to stacking waste batteries at will. This practice not only affects hygiene, but also causes great pollution to the surrounding environment. The correct storage method should place the battery in a dry and ventilated place, avoiding direct sunlight and high temperature, so as to extend the battery life and reduce the number of waste batteries.

3. Correctly handle damaged batteries

How should we properly handle some damaged batteries? Generally speaking, it is not easy to handle batteries that have been mixed with other garbage separately. We should avoid mixing batteries with other items by mistake during use. For damaged batteries, special attention should be paid to taking measures to handle them, such as wrapping with insulating tape, storing them separately, etc., to prevent the leakage of harmful substances inside the batteries.

4. Do not discard batteries at will

Many people will directly discard or handle them at will when there are too many used batteries. This practice not only causes great pollution to the environment, but also harms the health of people around them. Therefore, citizens should develop a good habit of not discarding batteries at will, take used batteries seriously, and avoid irreparable losses to the environment.

5. Treatment through scientific and technological means

In modern society, scientific and technological means can also be used to treat harmful substances in batteries. In recent years, many waste incineration plants have begun to use high-tech means to professionally treat waste such as batteries as hazardous waste, effectively avoiding their harm to the environment. However, this method is costly and requires professional institutions to operate, so it is not a generally available method.

Batteries have become a must-have item for modern people’s lives. Whether it is daily life or work and study, they are indispensable. However, with the continuous development of battery technology, the problem of waste battery disposal has become more and more prominent. Unprofessional waste battery disposal methods will cause great pollution to the environment, so we need to pay attention to the disposal of waste batteries.

For batteries used in daily life, we should pay attention to properly dispose of waste batteries and never throw them away. Some professional institutions and supermarkets will set up waste battery recycling bins. We can put waste batteries into these recycling bins and add them to the classified garbage.

NOORI uses advanced production technology and environmentally friendly materials, which is more friendly to the environment. Choosing NOORI means getting along with the earth in a friendly way.

Mercury is a toxic substance that is not friendly to the environment and will have an adverse effect on the soil. If no intervention is made, it will take a long time for nature to recover. By using mercury-free batteries, you can reduce the risk of environmental pollution.

At the same time, mercury will slowly affect people’s physical health, which is harmful to human health. Long-term contact can cause mercury poisoning. By using mercury-free batteries, you can avoid the risk of contact with this toxic substance.

For environmental protection reasons, many countries and regions have enacted regulations that restrict or prohibit the use of mercury in batteries. Using mercury-free batteries ensures that you comply with these regulations and get along with the environment more friendly.

Compared with traditional batteries, mercury-free batteries are designed to give products a longer shelf life. This means that you can store them for longer without worrying about them losing power. At the same time, mercury-free batteries can usually be more stable in power output and service life, giving the product itself a more advantageous performance.

Overall, choosing mercury-free batteries is a more sustainable and responsible choice, which is good for the environment and human health. At the same time, the performance of the product itself is also improved accordingly. It is an all-round good choice.

NOORI uses advanced production technology and environmentally friendly materials, which is more friendly to the environment. Choosing NOORI means being friendly to the earth.

It should be stored in a dry, ventilated, room temperature environment, avoiding high temperature, high humidity and direct sunlight, otherwise it may cause battery leakage, failure or shorten the service life. When not in use for a long time, it is recommended to remove the battery from the device to prevent battery leakage from damaging the device.

2. Precautions for use:

Carbon batteries of different models and brands should not be mixed as much as possible, because their performance and power may be different, and mixing may affect the use effect and life of the battery. Pay attention to the direction of the positive and negative poles when installing the battery. Reverse installation may damage the device or even cause the battery to explode. Avoid mixing new and old batteries. The old battery has a low power and may become a load for the new battery, affecting the overall power supply effect.

3. Applicable equipment:

Carbon batteries are suitable for low-power, intermittently used equipment, such as remote controls, electronic clocks, flashlights, toys, etc.

For high-power, long-term continuous use equipment, such as digital cameras, MP3 players, etc., it is recommended to use large-capacity batteries or rechargeable batteries.

4. Battery level judgment:

When the device is slow to respond, the sound becomes smaller, the light becomes dim, etc., it may be a sign of low battery.

5. Environmental protection treatment:

Carbon batteries contain harmful substances. Do not discard them at will after use. They should be recycled in accordance with local environmental protection regulations.

For example, in the home, if carbon batteries are placed in a bathroom with high humidity for a long time, chemical reactions may occur inside them, causing the batteries to rust or even leak. For another example, mixing different types of carbon batteries in a toy may cause the toy to run unstably or run out of power quickly.

NOORI uses advanced production technology and environmentally friendly materials, which is more environmentally friendly. Choosing NOORI means getting along with the earth in a friendly way.

The voltage of dry cells is commonly 1.5V (such as noori R6/R03/R14/R20) and 9V (such as NOORI 6F22). Among them, 1.5V is the most common dry cell voltage, which is widely used in various small electronic devices such as flashlights, remote controls, digital cameras, etc. Dry cells of this voltage are generally composed of multiple single cells, and the voltage of each single cell is 1.5V. The 9V dry cell battery is usually used in some high-power devices, such as smoke alarms, burglar alarms, microphones, etc. It is composed of multiple 1.5V single cells connected in series.

In order to ensure the normal use of dry cells, we need to pay attention to the following points.

First, the voltage of the dry cell battery will gradually decrease with the extension of the use time. When the voltage drops to a certain level, the battery power will decrease and cannot meet the normal working requirements of the equipment. At this time, the battery needs to be replaced in time.

Secondly, during storage and use, the dry cell battery should be kept away from moisture and high temperature environment, otherwise it will cause the battery performance to deteriorate or even be damaged.

In addition, the dry cell battery should be installed correctly, avoiding reverse installation or short circuit to avoid battery short circuit, heating, leakage and other problems.

The correct selection of the dry cell battery voltage is essential for the normal operation of electronic equipment. Generally speaking, the battery slot of the device will indicate the required battery voltage. We only need to select the dry cell battery of the corresponding voltage according to the slot mark. If the wrong battery voltage is selected, it may cause the device to not work properly or even damage the device.

In addition to voltage, the capacity of the dry cell battery is also one of the factors that need to be considered. Capacity refers to the amount of electrical energy that the battery can store, generally expressed in units of ampere-hours (Ah). The larger the capacity, the longer the battery can be used. When choosing a dry cell battery, we can determine the required battery capacity based on the power consumption and usage time of the device. Generally speaking, devices with higher power consumption require batteries with larger capacity to ensure that the battery can continue to supply power.

In short, the voltage of dry batteries is one of the important knowledge that needs to be understood in daily life. Correctly selecting dry batteries with appropriate voltage and capacity can ensure the normal operation of the equipment and extend the service life of the battery. During use, we should also pay attention to the storage and use environment of the battery, as well as the correct installation method, so as not to cause harm to the equipment and personal safety.

Carbon batteries are cost-effective and are mainly used in children’s toys. Carbon batteries are light in weight and will not significantly increase the weight of toys, making it convenient for children to play with them. NOORI carbon batteries are strictly inspected before leaving the factory, with advanced process flow and good reliability. No leakage was found during use (remote control, quartz clock, electronic scale). Even if carbon batteries leak, they will be less corrosive to the positive and negative contacts of the battery compartment, springs and other hardware. Even if the leaked electrolyte gets on the circuit board, it will not easily cause it to be scrapped. Cleaning the leaked electrolyte will not affect normal use. The leaked electrolyte is less corrosive and will not cause problems if it gets on the skin, cloth, plastic parts, etc. Please wash it in time.

Carbon batteries have low “self-discharge”. Many expired carbon batteries still have power. Many expired carbon batteries that have not leaked can still be used. Carbon batteries are also safer, and the short-circuit current is not too high (no obvious heat). Carbon batteries have “good” compatibility and “high” internal resistance, and can be well compatible with some household appliances, such as: quartz clock movements, remote controls, flashlights, electronic scales and other small appliances.

Determine power requirements: Calculate the power or energy requirements of the device or application that requires a battery. Consider factors such as voltage, current, and operating time.

Understand the different types of batteries: There are various types of batteries, including carbon batteries, (e.g. 1.5v AA R6 carbon battery, 1.5v AAA R03 carbon battery, 1.5v D R20 carbon battery, 1.5v R14 carbon battery) alkaline batteries (e.g. 1.5v AA LR6 alkaline battery, 1.5v AAA LR03 alkaline battery, 1.5v LR14C alkaline battery, 1.5V LR20 D alkaline battery, 6LR61 9V alkaline battery, 12V MN21 23A alkaline battery, 12V MN27 27A alkaline battery), lithium-ion batteries (e.g. 18650 rechargeable 3.7V lithium-ion battery, 16340 rechargeable lithium-ion battery, 32700 lithium-ion rechargeable battery, etc.), lead-acid batteries, AA AAA NiMH batteries (e.g. AAA NiMH battery, AA NiMH battery, NiMH battery pack), etc.

Each type has different characteristics and is suitable for different applications.

Consider Environmental Conditions: Consider the environmental conditions in which the battery will be used. Some batteries perform better in extreme temperatures or high humidity (NiMH battery packs, 18650 rechargeable 3.7V Li-ion batteries), so it is important to choose a battery that can handle the environmental conditions of the application.

Weight and Size: If the battery will be used in a portable device, consider the weight and size of the battery to ensure it is suitable for your needs.

Cost: Consider your budget and the long-term cost of the battery, including factors such as lifespan and maintenance requirements (e.g. 1.5v AA Dual A Type C USB Rechargeable Li-ion Battery).

Safety and Reliability: Make sure the battery you choose is safe and reliable for your specific application. Look for a reputable brand and check for relevant certifications or standards compliance.

Rechargeable vs. Non-Rechargeable: Decide whether you need a rechargeable or non-rechargeable battery based on your usage patterns and whether frequent charging is appropriate for your application.

Seek Expert Advice: If you are unsure which battery is best for your needs, consider seeking advice from a battery expert or manufacturer.

By considering these factors, you can make an informed decision about the most appropriate battery for your specific needs.

The originator of dry batteries was born in the mid-19th century. In 1860, George Leclanche of France invented the carbon-zinc battery, which was easier to manufacture, and the initial wet aqueous electrolyte was gradually replaced by a viscous paste-like method, so when it was placed in a container, the “dry” battery appeared. In 1887, the British Wilhelm Hellesen invented the earliest dry battery. Compared with liquid batteries, the electrolyte of dry batteries is in a paste state, which will not leak and is easy to carry, so it has been widely used.

Today, dry batteries have developed into a large family with more than 100 types. Common ones include ordinary zinc-manganese dry batteries, alkaline zinc-manganese dry batteries, magnesium-manganese dry batteries, etc. However, the earliest invented carbon-zinc battery is still the most widely used type of modern dry batteries. In the continuous development of dry battery technology, new problems have emerged. People have found that although dry batteries are easy to use and cheap, they are useless after use and cannot be reused. In addition, since metals are used as raw materials, it is easy to waste raw materials, and discarded batteries will also cause environmental pollution. Therefore, NOORI uses more environmentally friendly materials and processes to manufacture, which has become a new direction.
