DBTLAP CMOS Battery for Compaq Mini CQ10-120LA

This replacement CMOS battery is designed specifically for the Compaq Mini CQ10-120LA laptop motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The lithium coin cell is supplied new and tested before shipping. Buyers who need a main laptop power battery should look elsewhere.

Sustained load behaviour

The battery provides a steady low current to maintain CMOS memory and the system clock while the laptop is powered off. It is not subject to high-drain cycles, so capacity degrades slowly over years rather than hours. The lithium chemistry delivers stable voltage across its service life. This part does not power the laptop during active use.

Practical limits of the standard interface

The cell fits the standard CMOS socket on the target motherboard and operates within normal lithium coin-cell voltage parameters. No soldering or additional wiring is required for installation. Compatibility is limited to the specified Compaq Mini model; other systems may use different connector types or voltages.

Questions about this item

How much power does the DBTLAP CMOS battery draw when the laptop runs all day?

The lithium CMOS battery supplies only a tiny standby current to keep the real-time clock and BIOS settings alive; it adds no measurable load to the main power system during daily use.

What must I already have to install this CMOS battery in my Compaq Mini CQ10-120LA?

You need the laptop itself with its motherboard accessible and a small Phillips screwdriver to open the case and reach the battery socket.

Will this DBTLAP cell work alongside the original 10-year-old components still inside the CQ10-120LA?

Yes, it is a direct replacement for the factory coin cell on that motherboard and maintains BIOS settings with the existing hardware.
