Motherboard / Industrial CMOS/RTC Backup Power

Application: Preserve BIOS/clock settings and SRAM data during power failure

Solution: CR2032 direct power supply for RTC (DS1302/DS3231/PCF8563)

Circuit: Battery + diode (anti-backflow) → Vbat

Power consumption: RTC static current ≈ 300nA~2μA, service life: 5~10 years

CMOS/RTC circuits on control boards feature low power consumption and require batteries with stable discharge characteristics and long-term reliability.

We provide battery solutions with low self-discharge rate, high capacity, wide temperature adaptability, and stable and reliable discharge performance.
