A computer BIOS support battery, also known as a CMOS battery, is a small battery located on the motherboard of a computer. It is responsible for providing power to the BIOS memory, which stores crucial system information such as the date and time, hardware settings, and boot sequence. Without the support of this battery, the BIOS settings would be lost every time the computer is powered off, leading to potential issues with system startup and functionality. Typically, these batteries last for several years before needing to be replaced. **

The iPhone battery display shows the service by indicating the current battery level as a percentage, typically located in the top right corner of the screen.

Alkaline batteries are generally considered to be better than zinc-carbon batteries. Alkaline batteries have a longer shelf life and higher energy density, meaning they can last longer and provide more power. They also perform better in high-drain devices such as digital cameras and flashlights. While zinc-carbon batteries are cheaper, alkaline batteries are a more reliable and efficient choice for most electronic devices. **
