CR2430D 3V 270mAh: The Sub-Zero Power Cell Built for the Cold Frontier

Unforgiving Climates Demand Uncompromising Power

When sub-zero temperatures hit, standard batteries choke, leading to dropped signals, corrupted data, and expensive maintenance runs. The CR2430D is engineered specifically to eliminate this vulnerability. Integrating a premium 270mAh capacity within the widely utilized 2430 form factor, this primary lithium manganese dioxide cell features a proprietary Low-Temperature (D-Series) electrolyte chemistry.

Whether your devices are deployed in the depths of an arctic winter or inside specialized cryogenic logistics, the CR2430D ensures non-stop performance across a brutal -55°C to +60°C thermal envelope.

What Makes the “D” Suffix the Engineer’s Choice?

In the battery nomenclature, the “D” stands for specialized low-temperature electrolyte formulation. Standard coin cells experience crystallization of the liquid electrolyte at temperatures below -20°C, causing internal resistance to spike and the voltage to crash.

The CR2430D overwrites this limitation:

• High-Mobility Ionic Flux: The D-series electrolyte retains low viscosity at -55°C, allowing lithium ions to move freely between the anode and cathode.
• The 270mAh Sweet Spot: Optimizing internal active materials allows this cell to deliver a true 270mAh capacity, outlasting competitive standard 2430 cells by up to 20% in sub-zero stress environments.
• Flat Discharge Profile: Delivers a reliable 3.0V plateau throughout most of its life cycle, protecting low-voltage microcontrollers (MCUs) from brownouts.
