Product Overview

What Are Lithium Button Cell Batteries?

Lithium button cell batteries, also called lithium coin cells, are compact primary lithium batteries designed for stable voltage output, long shelf life and high energy density in small electronic devices. Most lithium button cells use a 3V lithium manganese dioxide chemistry and are widely used in memory backup, medical electronics, automotive keys, sensors, security devices and portable consumer products.

Compared with alkaline button cells, lithium button batteries provide higher nominal voltage, better energy density and more stable discharge performance. Common models include CR2032, CR2025, CR2016, CR2450, CR2477, CR1632 and CR1220. For PCB-mounted applications, lithium button cells can also be customized with solder tabs, pins, leads or wire connectors.

PKCELL supplies standard lithium coin cells, special button batteries and lead/tab button batteries for B2B customers, device manufacturers and OEM projects requiring stable long-term power.

How to Choose the Right Lithium Button Cell Battery

The right coin cell depends on device size, current demand, operating environment, mounting method and target service life.

CR2032 vs CR2025 vs CR2016

These three models have the same 20mm diameter but different thickness and capacity. CR2032 is thicker and usually provides higher capacity, while CR2025 and CR2016 are used where thinner battery height is required.

Choose CR2032 when space allows and longer runtime is needed. Choose CR2025 or CR2016 for thinner product design.

When Should You Choose CR2450 or CR2477?

Larger coin cells such as CR2450 and CR2477 provide higher capacity and are suitable for devices requiring longer standby life, stronger backup support or more frequent operation.

Suitable for IoT sensors, security devices, instruments and industrial electronics.

Standard Coin Cell or Battery with Tabs?

Standard coin cells are used in battery holders. Coin cells with tabs or leads are used when the battery needs to be soldered or mounted onto a PCB.

For PCB backup, memory backup and industrial control boards, choose tabbed or leaded button batteries.

What Information Should You Provide?

To recommend a suitable model, PKCELL engineers need the device application, voltage requirement, size limitation, working current, pulse current, temperature range, lifetime target and mounting method.

For OEM projects, include drawings, connector requirements, tab direction and annual demand if available.
