Memory batteries, often referred to as backup batteries or coin cell batteries, are small, long-lasting batteries used to provide backup power to volatile memory devices such as CMOS (Complementary Metal-Oxide-Semiconductor) RAM and real-time clocks (RTCs). These batteries ensure that critical data, system configurations, and timekeeping functions remain intact even when the main power source is disconnected or unavailable. Memory batteries are commonly used in computers, embedded systems, and consumer electronics where data integrity and system reliability are paramount.
