CR2450 lithium manganese dioxide button cell battery is named according to IEC standards. Among them, C- is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode. CR- means the battery shape is button shape.
Lithium batteries contain unstable chemical materials, such as lithium, organic solvents and certain chemical components. Improper use of lithium batteries may cause the battery to heat up, fire or explode, which is very likely to cause injury. injury. .
If the CR2450 battery is charged, gas will be produced inside the battery, causing rapid expansion inside the battery, causing an explosion and fire.

Precautions for usesafe use of button batteries.
1. Do not stack batteries together in a messy or exposed manner. When using and storing batteries, avoid direct contact between the positive and negative terminals of the battery and avoid surface contact between the battery and other metallic materials. Because it will cause the battery to short circuit with strong current and generate a large amount of heat, causing the battery to fire and explode.
2. Do not throw batteries into fire. Batteries are extremely dangerous to throw into a fire and can explode and burn.
3. Do not heat the battery. When lithium batteries are heated to 100°C (212°F), the rubber rings and other parts used for sealing are made of materials such as resin, which can melt when heated, causing a leak electrolyte and short circuitsinternal ts. explosion and fire.
4. Do not solder directly on the surface of the battery. The heat generated during welding may damage the rubber sealing ring and other parts, causing electrolyte leakage and internal short circuit, possibly causing explosion and fire.
5. Do not charge the battery. If the battery is charged, gas will be produced inside the battery, causing rapid expansion inside the battery, resulting in explosion and fire.
6. Do not disassemble the battery. When the battery is disassembled, a throat irritating gas is produced. At the same time, the lithium flakes inside the battery can easily react strongly with water and air and cause an explosion.
7. Do not deform the battery. When heavy pressure is applied to the battery, the battery seal ring and other parts of the battery will be deformedand damaged, causing battery leakage and internal short circuit, causing battery heat, fire and explosion.
8. Batteries of different types cannot be mixed. Since different types of batteries, as well as old and new batteries, have different voltages and capacities, mixing them can cause the batteries to overdischarge, leading to the risk of expansion and explosion.
9. Install and use the battery correctly to avoid battery short circuits and incorrect installation of positive and negative poles. Different electrical devices must be equipped with corresponding batteries. When installing, make sure that the positive and negative poles of the battery match the positive and negative polarities of electrical appliances.
