The door magnetic alarm is a wireless sensor device widely used in the security field. It is mainly used to monitor the opening and closing status of doors, windows, drawers, etc., and trigger an alarm when they are opened abnormally. Its compact design and low power consumption make it highly dependent on button batteries for power supply. Typical application scenarios Home/shop anti-theft: push alarms to mobile phones or security platforms when doors and windows are opened abnormally. Epidemic isolation monitoring: real-time monitoring of the access control status of people in home isolation, and automatic alarms for illegal door openings. Elderly care: record reminders of medication through the switch of the medicine cabinet, or monitor the risk of not going out for a long time. Facility management: monitoring of illegal opening of fire hydrants/manhole covers; monitoring the ...

Button batteries are widely used in modern game cartridges, modern game console motherboards, and many newer handheld game consoles. The main uses are: Saving game saves: When the console's main power source is removed or exhausted, the button battery provides a weak, continuous power to a special memory chip on the motherboard. This chip is responsible for storing key information such as your game progress, settings, time and date. Without this button battery, once the main power is disconnected, your saves will be lost. Maintaining the real-time clock: Some newer or special-purpose game consoles have a built-in real-time clock. The button battery is responsible for maintaining the clock when the main power is disconnected, ensuring that the in-game clock system (such as the day and night cycle or event triggering in some games) remains accurate after the console is turned on. ...

Children's luminous shoes usually have LED light-emitting components on the soles or uppers. The colourful light-up feature makes them very popular among children and adds an element of fun to walking. Major brands around the world have currently launched luminous shoes for children. Parents should be careful when buying such products to avoid safety hazards. Luminous shoes mainly use two types of battery: lithium polymer and button batteries. Button batteries are mostly used for the power supply, typically two to power an LED. Disposable button batteries are preferable. Officials recommend that children's shoes be made with button batteries, as these do not pose a charging risk. Rechargeable batteries are more likely to accumulate heat in sealed shoes, posing a higher risk.   Safety first: When buying products, make sure you identify reputable manufacturers and avo...

Stability of battery performance under extreme temperatures The pace of life is accelerating and the application fields of the world, such as consumer applications, smart cities, smart living, smart healthcare and smart industry, are changing rapidly. This also poses a challenge for power supplies. Batteries are being used in increasingly extreme environments! How will the electrical performance and stability of batteries be affected by extreme temperatures? The battery is in a low temperature environment: A sharp increase in internal resistance: At low temperatures, the diffusion of electrolyte ions slows down. This significantly increases the internal resistance, causing a sudden drop in output voltage and potentially resulting in the device shutting down prematurely. Capacity attenuation: Experiments have shown that the discharge capacity of button batteries is lower at -15...

There is a need for vertical industries such as enterprise digital transformation, the creator economy, education and medical care. The global AI PC market is expected to experience explosive growth in 2025, with shipments surpassing 110 million units and a penetration rate of 35%-40%. China accounts for 42% of the global market and has a penetration rate of 38%, leading the world.

The combination of hybrid computing power, privacy protection and flexible interaction is driving the AI PC to become a new productivity tool. Power Glory's button battery enhancement technology addresses the issue of b...

What batteries are suitable for portable calculators? The button battery in the calculator is used as either the main or backup power source to ensure stable operation under various lighting conditions, as well as to maintain important memory data and settings. Its small size, reliability and long life make it ideal for portable calculators. Button batteries used in calculators play a vital role. Their applications are mainly reflected in the following areas: Mains power (for non-solar calculators) Button batteries are the only source of power for calculators that do not have a solar panel or cannot provide sufficient power, especially indoors or in low-light environments. It supplies a stable and continuous power supply to all of the calculator's electronic components (CPU, display, etc.), ensuring that the calculator operates normally. Backup power supply (for calculators w...

How to choose a suitable battery for your health tracker A health tracker is a wearable device that uses sensors and smart technology to monitor, record and analyze user health data in real time, aiming to help people better manage their health. It is an indispensable health assistant in daily health monitoring, sports fitness, and medical health. Let's take a look at how to choose a suitable battery for your health tracker. Check the battery type required for your device Check the manual: The device manual usually clearly indicates the required battery model (such as CR2032, CR2025, etc.). Check the old battery: If the battery has been installed, directly check the logo on its surface (such as voltage, size, model). Contact the manufacturer: If the model is not clear, you can consult the official website of the device brand or customer service. Key parameter matching Vo...

Trend towards miniaturization and lightweighting of batteries The miniaturisation and lightening of primary batteries is one of the core requirements for developing current electronic devices, particularly in light of the growing popularity of technologies such as the Internet of Things (IoT), 5G, wearable devices, medical implants and micro-sensors. Button batteries are a prime example of miniaturised primary batteries, meeting this trend through material innovation, structural optimisation and manufacturing process upgrades.   A material science breakthrough: The CR series has a high energy density and stable voltage. The use of nanostructured manganese dioxide increases the effective surface area of the electrode, improving reaction efficiency and reducing volume. It also avoids leakage risks and supports flexible batteries with thinner designs. Structural design o...
