This article explains the type and purpose of the CMOS battery used in Elo AIO TouchComputer

Each Elo AIO TouchComputer is equipped with a CMOS battery.

The two types of CMOS batteries used in Elo products are:

1. CR232 3V Lithium Coin Type battery
2. CR232 3V Lithium Coin Type with leads:

The following describes the purpose of CMOS batteries:

A CMOS (Complementary Metal-Oxide-Semiconductor) battery provides power to the CMOS chip on the motherboard of a computer, which is responsible for storing system settings and maintaining the system clock. Here's a more detailed explanation of its functions:

1. Maintains BIOS Settings: The CMOS battery powers the CMOS chip that stores BIOS (Basic Input/Output System) settings, such as system time and date, hardware configurations, and boot order. These settings are essential for the computer to boot and operate correctly.

2. Keeps System Clock Running: The CMOS battery ensures that the real-time clock (RTC) continues to run even when the computer is turned off. This keeps the system time and date accurate.

3. Prevents Data Loss: By providing a continuous power supply to the CMOS chip, the battery prevents the loss of configuration data when the computer is powered down. Without this battery, users would have to re-enter BIOS settings every time the system is restarted.

In summary, the CMOS battery is crucial for retaining important system settings and keeping the system clock accurate when the computer is not powered.
