Renata CR2477 Lithium Battery

Power your high-drain, precision electronic systems with the Swiss-engineered excellence of the Renata CR2477 Lithium Battery. As a premier subsidiary of the Swatch Group, Renata manufactures industrial-tier coin cells that stand out as the highest-capacity models in the entire 3V lithium button-cell category.  

The defining characteristic of the Renata CR2477 is its massive, high-density 950 mAh capacity rating. By taking advantage of a deeply scaled, ultra-thick 7.7 mm architecture, it packs nearly triple the running life of standard coin cells. This makes it the absolute industry standard for critical memory backup systems (PLC computers), high-end fitness tracking smartwatches, specialized medical equipment, and remote security transmitters.  

Key Features

• Highest Available Coin-Cell Capacity: Delivers an exceptional 950 milliampere-hour (mAh) pool of energy, engineered to sustain low-drain memory lines or high-pulse wireless hardware for years on end.  
• Ultra-Stable 3-Volt Discharge: Utilizes a premium Lithium Manganese Dioxide chemical matrix, maintaining a flat, reliable voltage curve across its entire life cycle to safeguard sensitive internal chipsets.  
• Industrial Temperature Thresholds: Built to endure brutal operating environments ranging from a freezing -40C all the way up to a blistering 85C—perfect for outdoor tracking nodes and unconditioned server bays.  
  
• Swiss Precision Hermetic Seal: Encased in a high-grade stainless steel shell with premium pressure contacts, preventing corrosive chemical leakage or outgassing from ruining expensive circuit boards.
