PK Cell LIR2025 3.6V 40mAh Coin Cell

This PK Cell LIR2025 is a rechargeable lithium-ion button cell delivering 3.6 volts and 40 mAh capacity. It measures 20 mm in length and 2.5 mm in diameter. The cell suits devices requiring a 2025-size lithium-ion power source.

Fits 2025 Holders Replacing DL2025 or CR2025

This battery fits equipment designed for the 2025 form factor and replaces types such as DL2025, ECR2025, BR2025, and CR2025-1W. It is not for devices needing a primary 3 volt coin cell or a higher capacity pack.

3.6 Volt Nominal Voltage Decides Compatibility

The nominal voltage of 3.6 volts determines whether this cell works in your device. Many 2025-size holders expect 3 volts, so verify the required voltage before purchase.

Questions about this item

Will the PK Cell LIR2025 fit the CR2025 slot on my older motherboard?

The LIR2025 shares the 20 mm diameter and 2.5 mm thickness of a CR2025, so it fits the same holder, but it delivers 3.6 V instead of 3 V — check the board manual before swapping.

How can I confirm the 3.6 V output is present after I install the battery?

Measure across the terminals with a multimeter set to DC volts; a fresh cell should read close to 3.6 V under no load.

Does the PK Cell LIR2025 pack include a holder or solder tabs, or must I source them separately?

The cell is supplied as a bare button battery; any PCB holder, solder tabs or wiring must be purchased separately.
