Replacement CMOS battery for Alienware M14x

This DBTLAP lithium coin cell restores BIOS settings and real-time-clock function on Dell Alienware M14x laptops. It is a direct motherboard component, not a main power pack, and arrives tested and ready to install.

Lithium chemistry ensures long retention

The cell uses lithium chemistry to hold charge for years, keeping date, time and firmware configuration intact while the system is off. No other specification determines compatibility.

Single battery in the package

The box contains one CMOS battery only; no tools, cables or software are supplied. Installers must provide their own opening tools and follow the laptop service manual for safe replacement.
