CR3832T 3V 850mAh Ultra-High Capacity Lithium Manganese Dioxide (Li-MnO2) Battery

The Heavy-Duty Power Solution for High-Drain Industrial IoT and Precision Medical Systems.

The CR3832T represents the pinnacle of high-capacity lithium coin cell technology. Engineered for applications where a standard coin cell lacks the endurance, the CR3832T delivers a massive 850mAh nominal capacity in a slim 3.2mm profile. This “T” (Technical) series variant is optimized for long-term discharge stability, making it the superior choice for high-end electronic devices requiring fewer maintenance cycles and maximum energy density.

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.
