Panasonic CR2450PA/2BL 3V Lithium Coin Cell Battery 2-Pack

The Panasonic CR2450PA/2BL is a straightforward but well-executed coin cell battery package designed for the wide range of small electronics that depend on the CR2450 form factor. Each cell delivers a nominal 3.0 volts using lithium manganese dioxide chemistry, which provides a stable discharge curve — meaning devices get consistent power rather than a gradual fade. Panasonic rates the shelf life at up to 8 years when properly stored, making these practical to keep on hand as replacements for key fobs, glucose meters, watches, and other intermittent-use devices.

What distinguishes this particular product from generic alternatives is the attention to safety and authenticity. The packaging is fully compliant with Reese's Law, the U.S. federal standard enacted to prevent children from accessing and swallowing coin cell batteries. Each package meets IEC 60086-4:2019 and ANSI C18.3M Part 2:2024 safety benchmarks. The batteries themselves are manufactured in Panasonic's Indonesia facility and packaged in the USA, providing a clear chain of custody that counterfeit or gray-market cells cannot match. For devices that operate in varied environments, the rated temperature range of 14°F to 140°F ensures reliable performance whether the battery sits in a garage door opener through winter or a car key fob in summer heat.
