Cr2450 button battery holder battery usage and precautions

 

CR2450 button type lithium manganese dioxide battery, named according to IEC standard. Wherein the C-takes the lithium metal as the negative electrode, the manganese dioxide as the positive electrode of the chemical cell system, and the CR-represents the shape of the battery as a button type, so it is also called cr2450 button battery.

 

2450 represents the standard size of the battery, the name of the button cell is the first two digits are the diameter  (less than 10 mm is one digit), the latter two digits are the thickness.24 in 2450 indicates that the diameter is 24.5 mm, and 50 represents the height of the battery is 5.0 mm.

 

Application range:

1. Used as backup power for instruments, instruments, industrial control boards, etc.

2. Light-emitting and sound-emitting electronic products;

 

Mode of use (in connection with the PCB board)

1, a battery seat is used; the battery seat is provided with a plug-in or a foot of a patch, The battery can be soldered on the hole or the pad of the PCB board, the battery is placed in the battery holder

2, spot welding is carried out on the battery, the upper pin is welded, and the battery with the foot is welded on the PCB board. It should be noted that:

(1) The spot welding of the battery will result in high temperature and pressure, which can damage the electrical property of the battery, so the non-professional manufacturer cannot spot-weld the battery.

(2) the spot-welded battery cannot pass wave soldering, which will cause a short circuit of the battery and lead to scrap;

 

Precautions for safe use: The inside of a lithium battery contains a chemically unstable chemical material, such as lithium, an organic solvent and some chemical components, and the use of a lithium battery in an erroneous manner can lead to heat, fire or explosion of the battery, which may cause personal injury. To avoid the use of batteries for accidents, please read the following instructions carefully:

1. Do not clutter the battery and stack together. The use and storage of the battery shall avoid direct contact of the positive and negative poles of the battery and avoid the contact of the battery with the surface of the other metallic material. This will result in a short circuit with strong current in the battery and a large amount of heat to cause the battery to fire and explode. 2. Do not throw the battery in the fire. It is extremely dangerous to put the battery in the fire, and it may cause explosion and combustion.

3. Do not heat the battery. When the lithium battery is heated to 100.degree. (212 F), the rubber ring and other parts for sealing are made of a material such as a resin, which may be melted when heated, resulting in an electrolyte leakage and an internal short circuit, which may cause an explosion to fire.

4. Do not weld directly on the battery surface. The heat generated during welding may damage the gasket and other parts of the seal, resulting in an electrolyte leakage and an internal short circuit, which may cause an explosion to fire.

5. Do not charge the battery. If the battery is charged, a gas is generated inside the battery, causing a sharp expansion of the inside of the battery and an explosion and a fire.

6. Do not split the battery. When the cell is split, a gas that stimulates the throat is created, while the lithium sheet inside the cell is extremely susceptible to a strong chemical reaction with water and air to produce an explosion.

7. Do not deform the battery. When the battery is applied to the strong pressure, 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, thus causing the battery to generate heat, fire and explosion.

8. The batteries of different models can not be mixed. The voltage and capacity of the batteries of different models and the old and new batteries are different, which can lead to the risk of expansion and explosion due to overdischarge of the battery.

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