Precautions for button type battery

　　1. The diameter and thickness (height) of the button type battery shall be noted when selecting the button type battery, which shall be selected according to the requirements of the installed electrical products.

　　2. Because the types of materials used for button type batteries are different, it depends on the electronic products. For example, silver oxide or silver peroxide batteries can be selected for pointer watches, and for digital watches; Due to the lighting and noise functions, the silver oxide battery with large capacity of potassium hydroxide (KOH) as electrolyte should be selected.

　　3. The use of button type battery in high temperature environment shall be avoided as far as possible to reduce the discharge loss of battery. 4) It is strictly forbidden to burn the used battery in a big fire because it will raise the temperature of the battery and cause it to burst.

　　4. It is not allowed to use electricity to weld leads on the battery during use. 6) Unless otherwise indicated, button type batteries are basically disposable batteries, so they cannot be charged to avoid bursting.

　　5. The positive and negative pole positions shall be prevented from being reversed during use. The appearance of button battery (anode tank) is generally marked with "+", that is, the positive pole. The round cover (cathode cover) without the mark is the negative pole.

　　6. Try to avoid holding the certificate and negative pole of the button battery with two fingers for a long time, or short circuiting the positive and negative poles of the battery with metal conductors, which will cause short circuit and damage to the battery.
