The role of low-temperature coin cell batteries

1. Role

- Provide stable electrical energy: In a low temperature environment, the low temperature button battery can continuously and stably output electric energy. Compared to ordinary batteries, their internal chemistry and structure are specially designed so that normal electrochemical reactions can occur at low temperatures (e.g. -20°C or even below -40°C) to produce electric current. This stable power output can provide reliable power support for a wide range of devices.

- Maintain the function of the equipment: ensure the basic functions of the equipment in the low temperature environment, such as data storage and time recording. Taking electronic watches as an example, in a cold environment, the low-temperature button battery can ensure that the watch runs normally, and there will be no time inaccuracy or stop working due to the temperature drop.

- Ensure circuit integrity: At low temperatures, the battery is able to maintain the normal operation of the circuits to which it is connected. Because when the performance of the battery is reduced by low temperature, it may cause the circuit voltage to be unstable, and the low-temperature coin cell battery can reduce the occurrence of this situation, so that the electronic components in the circuit can work normally according to the design requirements.

2. Fields of application

-Electronic Equipment

- Watch: It is one of the most common application scenarios for coin cell batteries. Watches used in polar expeditions or cold regions at high altitudes require a cryogenic coin cell battery to ensure accurate timekeeping. For example, some professional outdoor watches have a wide operating temperature range, and can still display the time, date and other functions normally, such as altitude measurement, compass, etc., in a low temperature environment, relying on a low-temperature coin cell battery.

- Small electronic calculator: A calculator used in a low-temperature outdoor working environment (such as a construction site in winter for simple calculation tasks) or in inventory management in a low-temperature environment such as a cold store, a low-temperature coin cell battery can ensure that the calculator is turned on and operated normally at low temperatures.

- Medical equipment

- Implantable medical devices: Some implantable medical devices, such as pacemakers, require batteries to work reliably at low temperatures, although the internal temperature of the human body is relatively stable, but in some special situations (such as patients in cold environments), batteries are required to work reliably at low temperatures. Low-temperature coin cell batteries can meet this requirement and provide a guarantee for the stable operation of medical equipment.

- In vitro diagnostic devices: Some portable in vitro diagnostic devices, such as blood glucose testers, may be used under a variety of environmental conditions. In a cold outdoor environment, the low-temperature coin cell battery can ensure that the device starts and works normally, and accurately detects physiological indicators such as blood sugar.

- Automotive electronics

- Car key remote: In cold regions, the battery in the car key remote needs to work properly at low temperatures. The low-temperature coin cell battery can ensure that the owner can use the remote control to unlock, lock the car and open the trunk in a low-temperature environment.

- Tire Pressure Monitoring System (TPMS) Sensors: TPMS sensors installed inside car tires are affected by the ambient temperature. In cold weather, cryogenic coin cell batteries can make these sensors work properly, accurately transmitting information such as tire pressure to the car's control system.
