SONY Coin Cell Battery CR2450 3V Lithium With Pins
The Sony CR2450 is a compact lithium coin-cell battery, engineered to deliver reliable and stable 3-volt power in a very small and lightweight form factor. Its coin-shaped design (about 24.5 mm in diameter and 5 mm thick) makes it ideal for fitting into small electronic devices while maintaining sufficient energy capacity for long-term use.
Despite its compact size, the CR2450 packs a relatively high energy density enough to power devices for extended periods without frequent battery changes. Because it uses lithium chemistry (Lithium / Manganese Dioxide, Li/MnO₂), it provides a consistent voltage output throughout most of its discharge cycle, ensuring predictable performance even as the battery drains.
With a stable discharge curve, low self-discharge rate, and long shelf life, the Sony CR2450 is well-suited for small electronics that need dependable, long-term power without bulky batteries. Its small size and tab/pin or pin-lead design make it especially useful for devices where space is limited and compact power sources are required.
Features:
- High-energy lithium chemistry (Li/MnO₂) for long runtime.
- Stable 3 V output with smooth discharge — voltage stays consistent over the battery’s life.
- Compact coin-cell form factor (24.5 mm diameter, 5.0 mm thick) for space-constrained devices.
- Low self-discharge rate (≈ 1% per year), preserving stored charge for long shelf life.
- Good pulse-current capability can handle occasional bursts of higher current (useful for devices that demand short spikes of power).
- Non-rechargeable, primary battery with reliable long-term performance and minimal maintenance.
