Product Description

The CMOS (Complementary Metal-Oxide-Semiconductor) battery is a small, coin-shaped power cell mounted directly onto the motherboard of a desktop computer. Its primary role is to supply continuous power to the CMOS chip, which stores BIOS configuration settings and system time. When this battery fails, users may experience system errors, incorrect date/time settings, or the inability to retain BIOS configurations.

This CMOS Battery 5pcs pack is designed with Li-MnO2 (Lithium Manganese Dioxide) chemistry, delivering stable voltage and dependable energy storage over extended periods. Each battery provides an output voltage of 3V, a capacity of 220mAh, and a compact form factor of 20mm x 3.2mm, making it fully compatible with most standard desktop PC motherboards.

Ideal for IT professionals, PC enthusiasts, or anyone maintaining a fleet of computers, this economical pack ensures you always have a backup ready when needed. These are non-rechargeable, single-use batteries, and proper disposal after use is recommended.

Why You Need a Working CMOS Battery

Without a functioning CMOS battery, your desktop motherboard cannot retain important BIOS data or keep accurate system time. This can result in:

• Repeated BIOS reset to default settings

• Incorrect system clock and date

• Boot-up errors or time synchronization issues

• Problems with secure boot or hardware settings

Replacing your CMOS battery every 3 to 5 years is a simple and inexpensive way to maintain system reliability.
