series introduction
# Introduction to the CR - 2032/HSN Product Series
## 1. Overview
The CR - 2032/HSN product series represents a cutting - edge line of coin - type lithium batteries that have been engineered to meet the diverse power requirements of a wide range of electronic devices. These batteries are renowned for their high energy density, long - lasting performance, and exceptional reliability, making them a top choice for both consumer and industrial applications.
## 2. Technical Specifications
### Physical Characteristics
- **Size and Shape**: The CR - 2032/HSN batteries follow the standard CR2032 coin cell format. They have a diameter of approximately 20mm and a thickness of 3.2mm. This compact and uniform size allows for easy integration into various devices, as it is a widely recognized and compatible form factor.
- **Weight**: Each battery typically weighs around 3 grams, which is extremely lightweight. This makes them ideal for applications where minimizing weight is crucial, such as in wearable devices and small portable electronics.
### Electrical Performance
- **Nominal Voltage**: The nominal voltage of the CR - 2032/HSN batteries is 3V. This stable voltage output ensures consistent power supply to the connected devices, enabling them to operate smoothly without significant voltage fluctuations.
- **Capacity**: These batteries have a typical capacity of around 220mAh. The relatively high capacity means that they can provide power for an extended period, reducing the frequency of battery replacements.
- **Self - Discharge Rate**: The self - discharge rate of the CR - 2032/HSN series is very low, typically less than 1% per year when stored at room temperature. This allows the batteries to retain their charge for long periods, making them suitable for devices that are not used frequently.
### Temperature Range
- **Operating Temperature**: The batteries can operate effectively within a temperature range of - 20°C to 60°C. This wide operating temperature range makes them suitable for use in various environments, from cold storage facilities to hot industrial settings.
- **Storage Temperature**: They can be safely stored within a temperature range of - 40°C to 70°C, ensuring that they maintain their performance even under extreme storage conditions.
## 3. Product Features
### High Energy Density
The CR - 2032/HSN batteries offer a high energy - to - volume ratio. This means that they can store a large amount of energy in a small space, making them an excellent choice for devices with limited battery compartment space, such as key fobs, calculators, and small sensors.
### Long Shelf Life
Thanks to their low self - discharge rate, these batteries have a long shelf life. They can be stored for several years without significant loss of capacity, which is beneficial for manufacturers and distributors who need to stockpile inventory.
### Leak - Proof Design
The batteries are designed with a leak - proof construction. This prevents electrolyte leakage, which could damage the connected devices. The reliable sealing mechanism ensures the safety and longevity of both the battery and the device it powers.
### Excellent Discharge Performance
The CR - 2032/HSN series provides a stable and consistent discharge curve. This means that the voltage remains relatively constant throughout the battery's life, ensuring that the device operates at its optimal performance level until the battery is nearly depleted.
## 4. Applications
### Consumer Electronics
- **Key Fobs**: The compact size and long - lasting power of the CR - 2032/HSN batteries make them a perfect fit for car key fobs, garage door openers, and other remote control devices.
- **Wearable Devices**: In fitness trackers, smartwatches, and other wearable electronics, these
