Why do lithium button cell batteries have a long lifespan?

Lithium button cell batteries have a very long lifespan and can often last up to 10 years, even with little or no use.

They are characterized by extremely low self-discharge — typically only around 1% capacity loss per year — making them ideal for long-term applications.

Lithium button cells are commonly used in:

• Watches
• Medical devices
• Car keys
• Electronic devices
• Backup memory applications

Procell is one example of a brand that offers lithium button cell batteries.

Lithium batteries last a long time, sometimes up to ten years, even when they are not or barely used. Each year, self-discharge is only 1% of the capacity. Procell is an example of a brand that offers button batteries.
