CR2450HR 3V 550mAh Primary Button Cell for Tracking Locating Devices

Maxell has introduced two new heat-resistant batteries for on-board tire pressure monitoring systems designed to meet new federal regulations requiring automatic warning of faulty tires. Two high-temperature lithium-manganese dioxide coin cell batteries power the pressure-sensing label and mount on the rims of each wheel. The new CR2450-HR and CR2450HR-EX batteries are designed to meet new requirements. These designs include replacement gasket materials, new crimp structures and improved content to operate in high temperature environments encountered on wheels of rotating cars and light trucks. Heat-resistant batteries provide a nominal voltage of 3V, a lithium battery with a minimum life of at least five years, and can replace two batteries with another chemical. The basic parameters of this CR2450HR battery are as follows: 3V550mAh, size is 24.5*5.0mm, temperature is -40~125°C. It can be seen from the following Relationship between Discharge Current and Discharge Capacity that the discharge capacity of the battery varies with the discharge current at the same voltage and different ambient temperatures. When the ambient temperature is -10 °C, the battery has a capacity of 505 mAh at a discharge current of 0.5 mA. When the discharge current is 1 mA, the capacity of the battery drops to 410 mAh, and as the discharge current increases, the capacity of the battery decreases rapidly. When the ambient temperature is 20 ° C, the battery has a capacity of 550 mAh at a discharge current of 0.5 mA, and when the discharge current is 1 mA, the capacity of the battery decreases to 500 mAh, and as the discharge current increases, the capacity of the battery rapidly decreases. When the ambient temperature is 60 °C, the battery has a capacity of 550 mAh at a discharge current of 0.5 mA. When the discharge current is 1 mA, the capacity of the battery drops to 540 mAh, and as the discharge current increases, the capacity of the battery slowly and steadily decreases. When the ambient temperature is 100 °C, the battery has a capacity of 535 mAh at a discharge current of 0.5 mA. When the discharge current is 1 mA, the capacity of the battery decreases to 530 mAh, and as the discharge current increases, the capacity of the battery slowly and steadily decreases.
