What is a lithium button battery?
Lithium button batteries are small, round batteries commonly used in small electronic devices such as calculators, watches and digital thermometers. It is called a “button cell” because its shape resembles a small, flat button.

These batteries are known for their long life, high energy density, and ability to maintain a stable voltage output. They are usually made of lithium or lithium-ion chemicals and come in a variety of sizes and capacities. The most common sizes are CR2016, CR2032, and CR2025.

Button batteries are commonly used in low-power devices because they have a relatively low capacity and cannot generate high currents. However, their small size makes them ideal for use in devices with limited space. Caution: Improper handling or disposal of lithium batteries may cause danger. Therefore, collect or dispose of lithium batteries according to local regulations.

Performance test
There are several performance tests commonly used to evaluate the performance of lithium button batteries. These tests are commonly used to assess factors such as a battery’s capacity, discharge characteristics and shelf life. Some common tests include:

Capacity test: This involves measuring how much energy the battery can store and deliver. Capacity is usually measured in milliampere hours (mAh).

Discharge test: This involves discharging the battery at a constant rate until a predetermined voltage is reached. Discharge rates can vary depending on the application, but are usually around 0.2C or 0.5C.

Cycle life test: This involves charging and discharging the battery multiple times to assess its long-term performance. The number of cycles a battery can withstand before its performance degrades is an important factor in its overall life.

Shelf life testing: This involves storing the battery at a specific temperature and humidity for a period of time to assess how well it maintains capacity and performance over time.

Environmental testing: This involves exposing the battery to a variety of environmental conditions, such as high temperature, humidity, or vibration, to assess its durability and reliability under harsh conditions.

These tests are usually conducted according to industry standards, such as IEC 60086 or ANSI C18.1M. The results of these tests can be used to determine whether a battery is suitable for a particular application and to ensure that it meets relevant safety and performance standards.
