Compatible CMOS battery for Compaq Mini 110C-1120SS

This lithium CMOS battery replaces the BIOS RTC cell on the motherboard of a Compaq Mini 110C-1120SS laptop. It restores system time and CMOS settings when the original coin cell is depleted. The part is intended for repair technicians or owners performing board-level maintenance. It is not a main laptop battery and will not power the system.

Low power draw and silent operation

The cell draws only microamp-level current to maintain the real-time clock and CMOS memory. It produces no audible noise and generates no measurable heat during normal operation. The lithium chemistry provides a stable voltage over its service life. No active cooling or external power is required.

Single battery included in package

The box contains one tested CMOS battery ready for installation. No cables, brackets, software or additional hardware are supplied. The battery is verified before shipping to confirm basic functionality. Buyers needing a main power pack or multiple spares must source those separately.

Questions about this item

How do I install the CMOS battery in my Compaq Mini 110C-1120SS and which step is often missed?

Open the chassis, locate the coin-cell holder on the motherboard, insert the new lithium cell with the positive side facing up, then re-enter the BIOS to set the date and time — the step most people forget.

What maintenance will this CMOS battery need later?

The lithium cell requires no routine maintenance; when the system clock drifts or BIOS settings clear, simply swap in a replacement coin cell.

What limit appears first under sustained use of this CMOS battery?

The cell's finite capacity is the limiting factor; after several years of continuous powering the real-time clock, voltage drops enough to lose BIOS settings.
