Duracell CR2 Lithium Coin Cell Battery 3 Volts

Product Description

The DURACELL 00041333662039 is a CR2 lithium coin cell battery rated at 3 volts. This single-cell battery delivers stable DC power in a compact button form factor measuring 26 millimeters in height and 15 millimeters in diameter. Lithium chemistry provides a long shelf life and reliable discharge across a wide temperature range, making it suitable for low-drain and pulse-drain devices. HVAC technicians, electricians, and pool service professionals commonly use CR2 cells to power thermostats, remote controls, electronic gauges, and diagnostic equipment kept in service vans or job-site kits.

The CR2 form factor is widely used in portable electronic devices encountered in trade and light commercial settings. Typical applications include programmable thermostat remotes, combustion analyzers, digital calipers, laser levels, and handheld meters. This battery ships as a single unit, making it practical for stocking individually or sourcing as a one-for-one replacement when a device battery fails on the job.
