3.6V LITHIUM-THIONYL CHLORIDE TYRE PRESSURE MONITORING SYSTEM BATTERY ER2450 Lithium thionyl chloride wafer cell with PCB flat S+ S-. 3.6V 500mAh. Long life. Non-rechargeable. Li-SOCL2 battery ER2450 for TPMS The tire-pressure monitoring system (TPMS) is very important to ensure vehicle safety, while its life depends on the quality of batteries inside sensors. Currently, most battery manufacturers declare 3 years of working life, However, Fanso TPMS battery can operate much longer and avoid the trouble of battery replacement. The tire-pressure monitoring system (TPMS) is an electric system designed to monitor the air pressure inside the pneumatic tire on various types of vehicles. TPMS could report real-time tire-pressure information to the driver and improve vehicle safety. Long shelf life: self discharge rate less than 1% at 25°C. High energy density (700Wh/kg). Long operating life. Stainless steel container and end caps. Wide temperature range: -55ºC ~ +125ºC. Hermetic glass-to-metal sealing. Non-flammable electrolyte. Compliant with IEC86-4 safety standard. UL Component Recognition MH46165. High and stable operating voltage.
