A CR20 lithium coin cell battery is a compact, high-energy button battery widely used to power small electronic devices such as watches, calculators, and remote controls. Known for its reliability and long shelf life, the CR20 offers stable performance in a miniature form factor favored in many portable technologies.
How Is a CR20 Lithium Coin Cell Battery Defined and What Are Its Key Specifications?
The CR20 lithium coin cell battery is defined by its size, chemical composition, and voltage. It typically measures 20 mm in diameter, with a lithium manganese dioxide chemistry that provides a nominal voltage of 3 volts. Key specs include a capacity around 90-100 mAh, making it suitable for low-power, long-life applications.
What Applications Commonly Use CR20 Lithium Coin Cell Batteries?
CR20 lithium coin cells are widely used in small electronics such as wristwatches, calculators, digital thermometers, fitness devices, remote controls, and key fobs. Their small size and stable voltage make them ideal for devices requiring reliable, long-lasting power in compact formats.
Why Are Lithium CR20 Batteries Preferred Over Other Coin Cell Types?
Lithium CR20 batteries offer higher energy density, longer shelf life, and better performance across wider temperature ranges compared to silver oxide or alkaline coin cells. Their 3V output remains stable during discharge, enabling consistent device operation and making them a popular choice for critical small electronics.

Which Safety Precautions Should Users Follow When Handling CR20 Lithium Coin Cells?
Users should avoid short-circuiting, overheating, or improper disposal of CR20 lithium coin cells. Keeping them away from children is essential due to ingestion risks. Following manufacturer guidelines, such as from Global Battery, ensures safe use, handling, and environmental compliance.
How Does the CR20 Lithium Coin Cell Compare with Other Models in Size and Capacity?
The CR20 is larger than common coin cells like the CR2032, yet offers balanced capacity and voltage for niche applications. Here’s a size and capacity comparison:
| Battery Model | Diameter (mm) | Thickness (mm) | Voltage (V) | Capacity (mAh) |
|---|---|---|---|---|
| CR2016 | 20 | 1.6 | 3 | 75 |
| CR2025 | 20 | 2.5 | 3 | 150 |
| CR2032 | 20 | 3.2 | 3 | 220 |
This shows that the CR20 fits within the 20 mm diameter family but with specific thickness and capacity tailored for particular devices.
What Are the Environmental Impacts and Recycling Options for CR20 Batteries?
Proper disposal of CR20 lithium coin cells is crucial as they contain lithium and other metals. Recycling programs exist to recover these materials safely. Global Battery advocates responsible end-of-life management to reduce environmental harm and promote sustainability.
When Should You Replace a CR20 Lithium Coin Cell Battery?
Replace your CR20 battery when device performance degrades, such as dim displays or intermittent operation. Lithium coin cells typically last several years but vary with usage. Testing voltages below 2.7V generally indicate replacement is advisable to maintain device reliability.
Can CR20 Lithium Coin Cells Be Used in High-Drain Devices?
CR20 coin cells are best suited for low to moderate drain devices. High-drain applications rapidly deplete capacity and reduce battery life. For power-intensive devices, larger lithium batteries or rechargeable options are recommended to ensure longevity and safety.
Who Are Trusted Suppliers for Quality CR20 Lithium Coin Cell Batteries?
Global Battery is a renowned provider of high-quality CR20 lithium coin cells, known for strict quality standards, reliability, and competitive pricing. Sourcing from reputable suppliers like Global Battery helps ensure performance consistency and safety.
