Smoke and fire accident!What should I be aware of, storing and disposing of "mobile batteries"?

Mobile batteries, when not using?

　"Mobile battery" is useful for charging smartphones when going out, but in recent years the number of smartphones equipped with large -capacity batteries has increased, so many people may not use it as before.Some of them seem to keep them at home, thinking, "It's a waste to throw it away because I haven't used it so much, so it may be useful in the event of a disaster.However, for mobile batteries, there have been accidents such as smoke and ignition when use, and care must be taken when handling.[Video] Flame from garbage collection trucks!rupture!What should I be aware of when storing or disposing of mobile batteries that are no longer using mobile batteries?We asked a mobile battery manufacturer and an independent administrative agency Product Evaluation Technology Institute (NITE) Product Safety Center.

At least 40-50 % of the remaining amount

　First, we asked an anchor Japan (Chiyoda -ku, Tokyo) public relations representatives, developing, manufacturing, and selling digital products such as mobile batteries.Q.Please tell us about the service life of a mobile battery.Also, if the battery has expanded or the smartphone cannot be charged as before, is it better to stop using it and dispose of it?The person in charge "I will talk based on our products. Depending on the usage environment and conditions, the use of a built -in device with a lithium -ion battery installed in the mobile battery has been charged to about 300 to 500 times (100 %.Later, it is said that the battery is completely run out of the battery. If it exceeds that number, we recommend that you replace it with a new product. "The battery has expanded" "As before, smartphoneIf you can't charge ", it's evidence that the lithium -ion battery is deteriorating. Especially if the battery bulge can be confirmed, discontinue use immediately and dispose of it properly." Q..Please tell us about the precautions when using a mobile battery.The person in charge "Generally, lithium -ion batteries are sensitive to heat, so it tends to deteriorate when the battery temperature rises 45 degrees or more. As deterioration progresses, the power stored is reduced, which affects the life of the battery.It comes out. In addition, use in a cold environment that is less than 5 degrees, and storage also has an incredible effect on the battery. On the other hand, the battery can be charged without problems in 5 to 45 degrees.It is desirable to use and storage in "Q.How do you manage your product when storing a mobile battery with less than 300 times?The person in charge "When the mobile battery is stored for a long time, it should avoid high -temperature and humid places and charge about once every three months, and maintain the remaining battery level of at least 40 to 50 %.It is. If you leave it for a long period of time in a completely discharged state (the remaining amount is 0 %), the battery itself will be loaded and there is a risk that you will not be able to charge it when it is important.In the case of a lithium -ion battery that is not used, the battery level decreases (natural discharge) in a ratio of about 2 % per month (natural discharge) for a mobile battery of 10,000 Mille, Amper..It seems that some people buy not only dry batteries but also mobile batteries as disaster prevention supplies.Is it okay to store unused mobile batteries for a long time?The person in charge "There is no problem. However, even if it is unused, when stored for a long time, it avoids hot and humid as described above, and is charged about once every three months, at least 40-50.Please maintain the remaining battery level of about %. In order to prepare for a disaster, there are more types of ports (terminals) than mobile batteries, and many people have a large capacity and high -power portable power supply.However, the precautions regarding the use and storage of portable power are the same as a mobile battery. In order to prevent accidents and problems, it is recommended to choose a reliable manufacturer or brand product when purchasing a mobile battery or portable power supply."Masu" Then, we asked the Nite Product Safety Center about the dangers of an accident due to a mobile battery and the precautions for disposing of it.Q.Please tell us about the precautions when handling mobile batteries in your daily life.The person in charge "Use and storage in a high temperature environment will result in the deterioration of the battery. Also, it is possible that the impact will be added during use, which may lead to an accident with smoke and fire, so carrying and storing it.Please be careful when handling it. In the case of a mobile battery, the built -in lithium -ion battery may deteriorate if stored in a full charge or a complete discharge state, so about 80 % of regular charging.We recommend that you maintain a charging state. Some products have a storage method in the instruction manual, so please check it..What is the danger if a mobile battery is thrown away as a general garbage?Please tell us about the correct disposal method of a mobile battery.Person in charge "If a product equipped with a lithium -ion battery, such as a mobile battery, is discarded as a general garbage, the battery is compressed by a garbage collection vehicle causes fire and burst of products, causing burning and cleaning staff.The injuries may cause fire spread to nearby houses and fire in the incineration facility. Never discard them as general garbage. When discarding products equipped with lithium -ion batteries such as mobile batteries and smartphones.Please discard according to the instructions of local governments, including the sorting methods. In the general incorporated association that promotes the recycling activities of small rechargeable batteries, the lithium manufactured or sold by the member company based on the Effective Utilization Promotion Act.We collect small rechargeable batteries including ion batteries. The small rechargeable battery to be collected has a recycling mark on the surface of the battery. Small rechargeable batteries that are no longer needed are consumer electronics retailers.Please bring it to a cooperating store such as a home improvement store or to a cooperating municipality. Cooperation shops and cooperative municipalities can be checked on the JBRC website. "
