The "heart" of medical electronic devices: the selection and application of AG button batteries and CR button batteries

In the field of modern medicine, electronic devices play an increasingly important role. From portable blood glucose meters to implantable pacemakers, these devices provide strong support for the diagnosis, treatment and monitoring of diseases. As the "heart" of these devices, the choice of batteries is crucial. AG button batteries and CR button batteries have been widely used in medical electronic devices due to their excellent performance. This article will explore in depth the characteristics, application scenarios and considerations when choosing these two batteries.

1. AG button battery and CR button battery: performance analysis

Although AG button batteries and CR button batteries look similar, their internal chemical systems and application characteristics are significantly different:

AG button battery: usually refers to silver-zinc battery with a nominal voltage of 1.55V. Its positive electrode material is silver oxide, the negative electrode material is zinc, and the electrolyte is an alkaline solution. AG batteries are known for their stable voltage output, high energy density and low self-discharge rate.

CR button battery: usually refers to lithium-manganese battery with a nominal voltage of 3V. Its positive electrode material is manganese dioxide, its negative electrode material is lithium, and its electrolyte is an organic electrolyte. CR batteries have higher operating voltage, longer service life, and wider operating temperature range.

2. Application scenarios in medical electronic equipment

The performance difference between AG button batteries and CR button batteries determines that their application scenarios in medical electronic equipment have different focuses:

AG button batteries: With stable voltage output and high energy density, AG batteries are often used in medical equipment with high voltage stability requirements and relatively low power consumption, such as:

Hearing aids: AG batteries provide stable power support for hearing aids, ensuring clear sound quality and long-lasting battery life.

Blood glucose meter: AG batteries provide reliable power guarantee for blood glucose meters to ensure the accuracy and stability of blood glucose measurement.

Electronic thermometer: AG batteries provide long-lasting power support for electronic thermometers to meet the needs of daily body temperature monitoring.

CR button battery: Thanks to its higher operating voltage and longer service life, CR batteries are more suitable for medical devices with high power consumption or long-term use, such as:

Implanted pacemakers: CR batteries provide long-term and stable power support for pacemakers to ensure the safety of patients.

Portable defibrillators: CR batteries provide strong power support for portable defibrillators to ensure timely electric shock defibrillation in emergency situations.

Medical monitors: CR batteries provide reliable power guarantee for medical monitors to ensure continuous monitoring of patients' vital signs.

III. Selection and application: safety and performance

When selecting batteries for medical electronic equipment, the following factors need to be considered comprehensively:

Device compatibility: Different devices have specific requirements for battery voltage, size and capacity. Be sure to choose a battery model that is compatible with the device.

Safety: Medical electronic equipment is directly related to the life safety of patients, so safe, reliable and certified battery products must be selected.

Performance requirements: According to factors such as the power consumption, frequency of use and working environment of the device, select a battery with appropriate capacity, voltage and temperature range.

Brand reputation: Choose battery products produced by well-known brands to ensure product quality and after-sales service.

IV. Future development trend

With the continuous development of medical electronic equipment, the requirements for battery performance are getting higher and higher. In the future, AG button batteries and CR button batteries will develop in the following directions:

Higher energy density: Improve the energy density of the battery and extend the use time of the equipment.

Smaller volume: Reduce the volume of the battery to make the equipment lighter and more compact.

Safer and reliable: Improve the safety and reliability of the battery to ensure the life safety of patients.

V. Conclusion

As the "heart" of medical electronic equipment, the performance of AG button batteries and CR button batteries directly affects the normal operation of the equipment and the life safety of patients. Choosing the right battery model and using and maintaining it correctly are crucial to ensure the reliability and safety of medical electronic equipment. I believe that with the continuous advancement of technology, AG button batteries and CR button batteries will play a more important role in the medical field and protect human health.
