We often use the type of button batteries is not much, but in the large family of button batteries still have a lot of models and styles, and its features and characteristics are also different.
Button battery model standard
Button batteries in the international use of a more extensive, so there are GB standard models to regulate it, that is, in different markets at home and abroad to buy the button battery as long as the model is universal. Button battery models are generally marked in the battery cathode.
The button battery is composed of positive electrode, negative electrode and electrolyte. The surface is usually made of stainless steel and is used as the positive electrode. The negative electrode is made of stainless steel circular cover. The positive and negative electrodes are sealed with a sealing ring. Button Cell The sealing ring is made of nylon. To the insulation, but also to prevent leakage of electrolyte. It should be noted that, unlike the common No. 5 battery, the button cell side is the negative side, and the flat side is positive.
Button batteries are mainly a battery and secondary batteries, including a battery in accordance with the internal material, there are lithium batteries, alkaline batteries, silver oxide batteries and zinc air batteries, Button Cell these batteries can only be used once and can not charge.
Due to the compact size, the button battery has some other battery does not have the characteristics, but also its advantages and disadvantages of a reason. Its small stature is much smaller than the No. 5 battery, but it also provides much less energy than a large volume of batteries, so that it can be used in the need for small, but the use of space is very limited, especially heart pacing Devices, Button Cell electronic hearing aids in these products, can also provide very long battery life.
Button battery use precautions
1, before the first use of your electrical appliances to check whether the application of 3.0V lithium - manganese dioxide button cell, that is, whether the appliance with the battery match;
2, before installation to check the button battery extreme and the use of appliances and their contacts to ensure clean and good electrical conductivity, the equipment can not cause short circuit;
3, please understand the installation of positive and negative mark. Use, to prevent short circuit and positive and negative wrong;
4, the new button pool Do not mix with the old button batteries, different grades, Button Cell the type of battery do not mix, so as not to affect the normal use of the battery;
5, do not button batteries for heating, charging and thumping, so as to avoid damage, leakage, explosion, etc .;
6, the button battery can not be put into the fire, so as to avoid the risk of explosion;
7, do not put the button battery in the water;
8, do not put a lot of button batteries, long stacked together;
9, non-professionals do not disassemble, break the battery button to avoid danger;
10, do not keep the battery life in the high temperature (60 ℃ above), low temperature (-20 ℃ below), high humidity (relative humidity above 75%) environment, this will reduce the battery life expectancy, electrochemical performance and safety performance;
11, to avoid contact with strong acid, alkali, strong oxide and other strong corrosive substances;
12, properly keep the button batteries, to prevent young people, Button Cell infants and children swallowed the mouth;
13, pay attention to the use of the button battery period, so as not to affect the use of the battery over the use of efficiency, leaving your economy suffered losses;
14, pay attention to the use of button batteries Do not arbitrarily discarded in the river, river, lake, sea, field and other natural environment, but also not buried in the soil, the protection of the environment is our common responsibility.
