CMOS / BackUp battery

The CMOS/BackUp battery is a small and lightweight battery that stores the data used to maintain your computer’s settings, time, date, and other system configurations. It ensures that your PC turns on quickly and reliably every time you press the power button. The CMOS/BackUp Battery is an essential component of any modern computer. It is typically located near the CPU on the motherboard and looks like a small watch battery.

The CMOS/BackUp Battery helps your computer to preserve certain settings, such as the system time and date, system configuration options, BIOS setup menu options, memory information, etc. These settings are stored in an area of the RAM (Random Access Memory) called CMOS. The battery provides a stable power supply for the RAM, so that your settings won’t be lost if the system is turned off.

There are different types of CMOS/BackUp Batteries available on TypeBattery.com including Nickel-Metal Hydride (NiMH), Lithium-Ion (Li-Ion), Alkaline, and Lithium Primary. Each type of battery has its own unique features and benefits that make it suitable for specific applications. For example, NiMH batteries are well-suited for devices that require frequent battery replacements as they can hold their charge longer than other types.
