Duracell PX2025 Lithium Coin Battery 3V 5 Pack

Product Description

The DURACELL PX2025 / 4133304828 is a CR2025 lithium coin cell battery rated at 3 volts, sold in a 5-pack. It is engineered for professional and industrial devices that demand stable, long-lasting power from a compact cell. The flat form factor and low self-discharge rate make it well suited for equipment that sits in standby for extended periods. Design, safety, manufacturing, and qualification follow stringent battery standards that incorporate elements of ANSI and IEC battery standards. HVAC technicians, electricians, and service pros commonly use CR2025 cells in thermostats, remote controls, sensors, and handheld diagnostic tools.

This battery is packaged for professional trade use. The 5-pack is economically packaged for service vans and supply rooms where keeping spare cells on hand reduces callbacks. The operating temperature range of -22 degrees F to 158 degrees F makes it appropriate for both indoor equipment and installations in unconditioned spaces such as attics, crawlspaces, and mechanical rooms. Each cell features a bitter taste layer applied to the back to discourage accidental ingestion, and the tamper-proof double blister pack requires scissors to open, reducing child-access risk on the job site or in the home.

Installation Notes

Coin cell replacement is typically performed by any trade professional during routine maintenance or device commissioning. Always power down or remove the device from service before replacing the battery to avoid unintended control signals. Dispose of spent lithium cells in accordance with local regulations - do not incinerate or puncture. Keep batteries away from children and store unused cells in the original tamper-proof packaging until needed.
