Uniross CR2477T HT Lithium Coin Cell Battery | 3V 1000mAh High Temperature

Model No: CR2477T

The Uniross CR2477T HT is the highest capacity cell in the 24.5mm HT family and one of the most capable cells in the entire HT range, delivering 1000 mAh at a stable 3V in a 24.5mm diameter, 7.7mm profile. The tall 7.7mm height provides an electrode stack that delivers 1 Ah — the benchmark capacity for long-life industrial and infrastructure coin cells — with 8 mA continuous and 25 mA pulse ratings and the full -30°C to +80°C HT operating range. For demanding wireless infrastructure where multi-year battery life in high-temperature environments is a non-negotiable design requirement, the CR2477T HT is the definitive specification in the 24.5mm format.
