Precautions for safe use of CR2450 battery

Lithium batteries contain unstable chemical materials, such as lithium, organic solvents and some chemical components. Misuse of lithium batteries may cause the battery to heat up, catch fire or explode, which may cause personal injury. In order to avoid accidents caused by using batteries, please read the following instructions carefully:

1. Do not pile up the batteries in a disorderly and exposed manner. When using and storing the battery, avoid direct contact between the positive and negative electrodes of the battery, and avoid contact between the battery and the surface of other metal materials. Because this will cause the battery to be short-circuited with a strong current and generate a lot of heat, causing the battery to catch fire and explode.

2. Do not throw the battery into fire. It is extremely dangerous for the battery to be placed in a fire, it may explode and burn.

3. Do not heat the battery. When a lithium battery is heated to 100°C (212°F), the rubber ring and other parts used for sealing are made of materials such as resin, which may be melted when heated, causing electrolyte leakage and internal short circuits, This may cause an explosion and fire.

4. Do not solder directly on the battery surface. The heat generated during welding may damage the sealing rubber ring and other parts, resulting in electrolyte leakage and internal short circuit, which may cause explosion and fire.

5. Do not charge the battery. If the battery is charged, gas will be generated inside the battery, causing the inside of the battery to expand rapidly and cause an explosion and fire.

6. Do not disassemble the battery. When the battery is disassembled, a gas that irritates the throat will be produced. At the same time, the lithium sheet inside the battery is very easy to produce a strong chemical reaction with water and air, resulting in an explosion.

7. Do not deform the battery. When a strong pressure is applied to the battery, the sealing ring of the battery and other parts of the battery will be deformed and damaged, resulting in battery leakage and internal short circuit, which will cause the battery to heat up, catch fire and explode.

8. Batteries of different types cannot be mixed. Due to the different voltage and capacity of different types of batteries and new and old batteries, mixing them will cause the battery to over-discharge and cause the danger of swelling and explosion.

9. Correctly install and use the battery to prevent battery short circuit and wrong positive and negative poles. Different electrical appliances should be equipped with corresponding batteries. When installing, pay attention to whether the positive and negative poles of the battery are consistent with the positive and negative polarities of the electrical appliances.
