Customized Solutions


Customized on demand

According to the different needs of customers, OEM is different


Card processing

In order to keep the CR battery to meet the needs of users, the CR battery is processed by card mounting.


Coin Cell Battery of PIN

According to the needs of different customers, it can ensure the normal connection of different angles, and can process the welding line and the welding foot.

With the advent of the 5G era, a variety of intelligent products have entered every aspect of life, including many tags now also intelligent, such as electronic Bluetooth tags, through the cell phone connection can change the content of the tag, but also in the promotion of the tag color change, electronic Bluetooth tags are integrated molding, the battery capacity directly determines the service life of the tag, choose CR2032 specifications of the button battery A good choice.

3V button type lithium manganese battery CR2032, it is functional constant current 9mA discharge time extension, using sealed structure and manufacturing technology, with excellent leak-proof, lasting power, high energy, smooth voltage, mercury-free environmental characteristics, etc., capacity up to 240 mAh, size: 20 * 3.2mm.

The special production process and internal structure we use have a variety of integrated functions above, will be your ideal solution.

It has obvious advantages in the application of one-touch start module. A suitable battery needs to be selected for the power supply module of the key end of the one-touch start. Considering the light weight and portability of the product design, a coin cell battery is a more suitable choice for the key side.

The CR2032 coin cell battery has a nominal voltage of 3V and a nominal capacity of 240mAh, which can meet the demand for the battery capacity of the key side of the car and ensure the normal operation of the key side of the one-touch start system for a long time.

The CR2032 has an outer diameter of 20.0mm, a height of 3.2mm, and weighs only 3.0g. The small size of the product helps to enhance the compactness and portability of the keypad product design and reduce the trouble of carrying it around with users. They can work reliably under different ambient temperature conditions, with high reliability and safety, so users can choose them with confidence.
