The PK Cell CR2032 Battery: A Versatile Power Source for Everyday Devices**

Introduction

PK cell CR2032 batteries are small, coin-shaped batteries that are commonly used in a wide range of electronic devices, such as watches, key fobs, calculators, and medical devices. These batteries are known for their reliability, long shelf life, and low cost, making them a popular choice for manufacturers and consumers alike.

Chemical Composition and Construction

CR2032 batteries are primary batteries, which means they cannot be recharged. They are constructed with a manganese dioxide cathode and a lithium anode, separated by a non-aqueous electrolyte. The chemical reaction between these components generates an electrical current.

Specifications and Performance

CR2032 batteries have a nominal voltage of 3 volts and a typical capacity of 225 mAh (milliamp-hours). They can provide a continuous discharge current of up to 0.2 mA and a maximum pulse current of up to 10 mA. The operating temperature range for these batteries is typically -30°C to +60°C (-22°F to +140°F).

Advantages of PK Cell CR2032 Batteries

• Compact and lightweight: Their small size and low weight make them ideal for portable devices.
• Durable: CR2032 batteries are highly resistant to leaks, corrosion, and extreme temperatures.
• Long shelf life: They can retain up to 90% of their capacity for up to 10 years when stored properly.
• Low cost: CR2032 batteries are very affordable, making them a cost-effective option for manufacturers.
• Versatile: They can be used in a wide variety of electronic devices, from watches to medical devices.
