Uniross CR3832T HT Lithium Coin Cell Battery | 3V 850mAh High Temperature

Model No: CR3832T

The Uniross CR3832T HT is the flagship of the HT range — 850 mAh at a stable 3V with 20 mA continuous and 75 mA pulse current ratings, and the full -30°C to +80°C HT operating envelope. No other cell in the Uniross HT portfolio matches the combination of capacity, peak current, and temperature qualification that the CR3832T HT delivers. The 38mm electrode area sustains 75 mA bursts without voltage collapse in extreme thermal environments, making the CR3832T HT the definitive specification for the most demanding temperature-rated industrial, military, and critical infrastructure applications.

Product Features

  • 20 mA continuous / 75 mA pulse — highest current in the HT range — the only Uniross HT cell rated for 75 mA pulse; sustains high-current bursts in extreme thermal environments where no smaller coin cell format is viable
  • 850 mAh — highest capacity in the HT range — 850 mAh with full temperature qualification; designed for devices where high current delivery and multi-year battery life are both critical in deployments exposed to -30°C to +80°C
  • -30°C to +80°C operating range — the full HT envelope with the largest electrode area in the range; heat-resistant electrolyte, reinforced shell, and advanced sealing maintain integrity under the most severe thermal cycling conditions
  • 7-year shelf life — matches the deployment and storage timescales of critical infrastructure, military, and long-lifecycle industrial programmes in temperature-variable environments
