Technical information
LIR2450 Coin Cell, 24.5mm, 120mAh, 120mA, 3.7V, Grade A Lithium-ion Rechargeable Button Cell — specifications and product details
Review the product information and manufacturer-related specifications below. Confirm the applicable datasheet and revision before engineering or procurement approval.
The 24.5mm LIR2450 lithium ion rechargeable coin cell is a relatively new innovation in coin cells. Traditionally coin/button cells were one-time use, non-rechargeable lithium batteries. However, in many cases a rechargeable coin cell is favorable. The new rechargeable LIR button cell uses lithium-ions to produce energy and offers high energy density (79Wh/kg), high voltage (3.7V), and a high cycle life (~500 cycles).
It is used in high-tech applications like wearables, Bluetooth headsets, body sensors, medical devices, wireless sensors, remote controls, toys, networking devices, and many others.
The LIR2450 ships from Hong Kong to anywhere in the world. Our facility in Dongguan, China provides additional services like insulation, custom brand etching, custom packaging, custom tabbing, or assembly into small-format coin cell battery packs.
This product is protected by warranty covering authenticity, performance, age, and defects.
Engineering and sourcing guide
What to check when sourcing LIR2450 Coin Cell, 24.5mm, 120mAh, 120mA, 3.7V, Grade A Lithium-ion Rechargeable Button Cell
Use the published product information and the applicable manufacturer datasheet to verify that this cell is suitable for the intended assembly. Specifications can differ by chemistry, cell format and manufacturer revision.
A loose cell is a component, not a finished battery system. Use it only within the manufacturer's stated limits and in an appropriately engineered assembly with suitable electrical, thermal, mechanical and protective measures. Do not infer safe operating limits from nominal capacity or voltage alone.
Frequently asked questions
Questions about LIR2450 Coin Cell, 24.5mm, 120mAh, 120mA, 3.7V, Grade A Lithium-ion Rechargeable Button Cell
