A CR2032 battery is a 3V lithium manganese dioxide coin-shaped cell commonly used to power small, low-drain electronic devices.
Key Product Features
- Reliable 3V Power: Delivers a stable 3V output with a typical capacity of approximately 210–240 mAh.
- Extended Shelf Life: High-quality cells maintain power for up to 10 years in proper storage, with a low self-discharge rate of about 1% per year.
- Wide Temperature Range: Operates effectively in extreme environments, typically ranging from -30°C to +60°C (-22°F to 140°F).
- Leak-Proof Construction: Innovative sealing technology prevents leakage to protect your expensive electronics.
- Safety Features: Often available in child-resistant packaging to prevent accidental ingestion.
Common Applications
This versatile battery is a direct replacement for many household devices, including:
- Security & Entry: Car key fobs, garage door openers, and AirTags.
- Medical Devices: Blood glucose meters, digital thermometers, and oximeters.
- Computing: PC motherboard CMOS/BIOS batteries and calculators.
- Electronics: Watches, LED lights, small toys, and remote controls.
Because the CR2032 is a global standard for military electronics, it is cross-referenced by dozens of National Stock Numbers (NSNs) depending on the country of origin, the specific branch of service, and the "End Item" (weapon or vehicle) it supports.
Below is a comprehensive list of all major NSNs for the CR2032 lithium battery, categorized by country code.
United States (01)
