The CR2032HT, CR2050HT and CR2450HT high-temperature button cells are ideal for use in extreme temperature conditions from -40°C to 125°C. These cells meet the automotive sector’s high temperature requirements of 125°C, in contrast to the usual 70 to 85°C available on the market. They are also able to withstand other mechanical stresses such as shock and vibration. These high-temperature button cells are commonly used in tire pressure monitoring systems (TPMS).
Standard button cells are generally designed for a temperature range of around -20°C to +60°C. High temperatures can accelerate the chemical reactions within the battery, leading to faster ageing and a shorter service life. Conversely, at low temperatures, the capacity of the cell can drop by up to 50%, as the internal resistance increases and the chemical reactions are slowed down.
The high-temperature button cells CR2032HT, CR2050HT and CR2450HT from Jauch have been optimized precisely for these effects and function reliably even in the extreme temperature range from -40°C to +125°C. The chemical composition of these cells is based on lithium manganese dioxide, which is known for its high stability even at extreme temperatures. This technology offers high performance and a wide temperature range. At high temperatures, cells tend to self-discharge at an accelerated rate. This is where Jauch comes in, through targeted optimization of the materials, particularly in the selection of the electrolyte, the self-discharge of the high-temperature cells has been significantly reduced, ensuring a long service life for the cells. Various cell sizes, capacities and arrester variants are available.
The extremely resilient high-temperature cells can be used in electronic toll collection systems (ETC), asset tracking and tire pressure monitoring systems (TPMS) in the automotive industry.
