Car Keys / Remote Controls

Requirements: 3V, instantaneous pulse 10~15mA, reliable at low temperatures, small size

Solution: CR2032 (mainstream), low internal resistance high-pulse type

Design: Parallel 10~47μF low-ESR capacitor to buffer pulses and prevent voltage drop-induced reset

Service Life: 1~2 years with 5 presses per day

Remote control devices such as car keys feature low static power consumption and high instantaneous current pulses. We can provide battery solutions with fast pulse response and stable discharge voltage platform.
