Key Performance Advantages
1. Unrivaled 850mAh Energy Density
The CR3832T is a "large-format" coin cell. By utilizing a 38mm footprint, it provides 850mAh high capacity. This massive energy reservoir is critical for high-drain sensors and devices that transmit data over long distances.
2. Stable 3V Discharge Platform
Engineered with high-purity electrolytic manganese dioxide, the CR3832T maintains a exceptionally flat discharge curve. It ensures a consistent 3.0V output for the majority of its service life, protecting sensitive ICs from voltage-drop errors.
3. Industrial-Grade Reliability & Sealing
Our CR3832T features an upgraded casing and a high-performance heat-resistant gasket. This design prevents electrolyte leakage even under significant vibration or fluctuating atmospheric pressure.
4. 10-Year Shelf Life
Thanks to its low self-discharge chemistry, the CR3832T retains over 90% of its initial capacity after 10 years of storage, making it the ideal choice for mission-critical backup power and "set-and-forget" industrial installations.
