The BIOS Battery 2032 Lithium (also known as a CMOS battery) is a small, round lithium coin cell battery that provides constant low‑power energy to your computer’s motherboard so it can retain critical settings like the system time/date and hardware configuration even when the computer is turned off. It’s a standard component in desktops, laptops, servers, and other electronics that require backup power for memory circuits. This battery is compact and lightweight, designed to fit into the dedicated battery holder on the motherboard or into specialized connectors. Thanks to its lithium chemistry, it offers a long shelf life, low self‑discharge, and reliable performance over many years — typically lasting 5–10 years before needing replacement
