Battery Cells Can Operate At High Temperatures

Developed for use in on-board tire pressure monitoring systems, CR2450-HR and CR2450HR-EX Li/MnO2 coin cell batteries can withstand temperatures ranging from -40°C to +120°C and -40°C to +150°C, respectively. Both cells measure 24.5 mm in diameter x 5 mm high and have a nominal voltage of 3V. The HR cells have a standard capacity of 550 mAh, weigh 6.8g, and are for standard-size vehicles, while the HR-EX cells have a 525 mAh capacity, weigh 6.7g., and are for high-performance, premium vehicles. The new heat-resistant cells are also expected to find use in compact equipment requiring small-sized batteries. Pricing to TPMS manufacturers for both batteries starts at about $1 each.
