It's because of the revival when the battery is turned around ...?

　A battery that moves a little home appliances around you. There are a wide variety of types and sizes, but there are many people who usually use it without worrying about it, and at the timing of replacement, and many people are lost in size, type, and disposal method. In 1963, I asked Katsuhiko Ikeda, a consumer product representative of Maxel Co., Ltd., who produced alkaline batteries for the first time in Japan. [Image] "Ochi → Ryo" seems to express "understanding" for his older teens -what is the difference between manganese batteries and alkaline batteries? "Mangan batteries are long history and are used all over the world. It has the characteristic that the voltage recovers when used on vacation, and is used in small power, such as clocks and toys. Alkaline batteries are powered. It is strong, and it has about twice as much as the same size manganese battery. Use it for those that require power such as model vehicles, electric toothbrushes that require large current, and those that require power. Will be done -is there a difference in standards, such as AA -2, etc., besides the size of the battery? "In the case of the same type, the ingredients used in any standard are the same, but the amount is different. A single type is maximum, and as the number increases, the content and power become smaller. By the way, in the case. The word "single" is an abbreviation of "unit bases". It is not a battery that summarizes several, but it is called a single battery, and it is called a single 1, a single 2. From 1942, it seems that only Japan uses this name. "And what you want to be careful about when replacing batteries. The terminals at both ends of the battery are made of metal, so if you touch other metals and batteries, you may be short and cause accidents such as fever, ignition, and rupture. According to Mr. Ikeda, "Wrap both ends of the battery so that it is wrapped with cellophane tape or vinyl tape, be sure to insulate it, and then throw it away according to the instructions of your home." By the way, is the tricks such as "Rubbing both ends when the battery runs out" is true? When I asked a question, after saying, "I can't recommend it because of the various theories, but it is affected by the environmental temperature because the battery creates electricity in a chemical reaction. Especially in winter. In a cold environment, holding the battery by hand will warm the contents of the battery that still remained a little, making it easier to react to chemical reactions, and may temporarily revive. " However, if the remaining battery is left as it is, it may cause problems such as liquid leakage, so please replace it with a new one as soon as possible. We want to handle the batteries familiar to us and to dispose of them correctly. (Coverage / sentence = Chiaki Murakawa)
