Deep-sea exploration equipment, such as submersibles and underwater robots, requires batteries that can operate stably in high-voltage and low-temperature environments. When choosing disposable button batteries for underwater robot beacons, lithium-manganese batteries are the most commonly used and recommended choice, particularly the CR series. Power Glory's lithium-manganese batteries play a vital role in these fields due to their unique advantages. Voltage Stability: Lithium-manganese batteries provide a stable 3V voltage (common models include CR2032, CR2450, and CR2477) until nearly depleted. This is crucial for beacons that require precise voltage for positioning or communication. High Energy Density and Long Life: Lithium-manganese batteries offer higher capacity and a longer lifespan than alkaline batteries for the same volume. This is extremely important ...

Military night vision goggles exemplify high-tech empowerment of individual combat and are essential equipment for modern militaries. They significantly enhance soldiers' situational awareness, mobility, and combat capabilities in darkness or low-light environments. They have revolutionized nighttime combat and are crucial for modern militaries to gain information advantage and initiative on the battlefield. The core principle of military night vision devices is to enhance weak light, primarily image-intensified devices. The most common core operating principles are: Photon collection: The objective lens collects extremely weak ambient light. Photoelectric conversion: Light strikes the photocathode, converting photons into electrons. Electron multiplication: Electrons are accelerated and multiplied by collisions in the microchannel plate, generating a large number of electrons...

A pacemaker is a small electronic medical device implanted in the body, primarily used to treat a slow heartbeat (bradycardia). Its core function is to monitor the heart's own electrical activity and, if the heart beats too slowly or stops, send weak electrical pulses to stimulate the heart muscle, causing it to contract at a normal rate and thus ensuring adequate blood supply to the body. The design of these batteries must meet the stringent requirements of implantable medical devices for long life, high safety, and stable voltage. Non-rechargeable design Pacemaker batteries need to be implanted  the body for extended periods. Disposable (non-rechargeable) batteries can avoid safety risks (such as heating and leakage) caused by repeated charging and discharging. Currently, mainstream products is disposable lithium batteries, which typically require replacement every 5-10 yea...

A thermometer and hygrometer is a small electronic device used to monitor the temperature and humidity of the environment. Its design usually needs to take into account low power consumption, long life and high accuracy. Button batteries are an ideal power source for thermometers and hygrometers because of their small size, high energy density and stable discharge. The core advantages of button batteries in thermometers and hygrometers Volume and energy efficiency adaptability Thermo-hygrometers often need to be embedded in small spaces (such as household sensors and industrial recorders). Button batteries (such as CR2032 and CR1220) are usually ≤20mm in diameter and only 3–6mm thick, which perfectly matches the needs of device miniaturization. Its energy density is significantly higher than that of cylindrical batteries. For example, CR2032 has a capacity of abou...

A sports bracelet, also known as a fitness tracker or smart bracelet, is a small electronic device worn on the wrist that is mainly used to monitor and record the user's physical activity, health status and sleep quality. It uses various sensors to collect data and synchronizes with a smartphone via Bluetooth to display detailed analysis reports on the accompanying APP. Advantages of using a lithium micro battery in a sports bracelet  Button batteries are often used in sports bracelets to meet the requirements of lightweight, long battery life and safety.  Unique packaging technology with low self-discharge.  Leak-proof design, high capacity and other advantages are suitable for bracelets with functions such as step counting and time display.  The cost is relatively low compared to other batteries.  Users can purchase and replace batteries by themselves without wait...

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...
