Uniross CR2335T HT Lithium Coin Cell Battery | 3V 300mAh High Temperature

Model No: CR2335T

The Uniross CR2335T HT delivers 300 mAh at a stable 3V in the 23mm diameter, 3.5mm profile — the highest-capacity standard-height cell in the 23mm HT family. The 3.5mm depth maximises the electrode area available within common 23mm device housings, delivering 300 mAh with 6 mA continuous and 20 mA pulse ratings and the full -30°C to +80°C HT operating range. The CR2335T HT is the first-choice specification for 23mm applications where runtime is the primary constraint alongside temperature qualification.

Product Features

  • 300 mAh — highest standard-height capacity in the 23mm HT family — the 3.5mm profile extracts maximum electrode area from standard 23mm housings; the specification of choice when runtime is the priority in a temperature-qualified 23mm design
  • 6 mA continuous / 20 mA pulse — full 23mm HT current class for demanding wireless protocols, sensor bursts, and duty-cycled RF transmission in extreme temperature environments
  • -30°C to +80°C operating range — advanced heat-resistant construction for automotive, outdoor infrastructure, oil and gas, and high-ambient industrial deployments
  • 7-year shelf life — enables multi-year battery life for infrastructure and industrial devices with infrequent maintenance access
