Compatible CMOS Battery

This DBTLAP CMOS battery is a direct replacement for the Dell Alienware M11x R3 laptop motherboard. It restores BIOS settings and real-time clock function when the original cell fails. The lithium coin cell is intended for repair technicians and owners servicing this specific model. It is not a main laptop power battery and will not suit other hardware.

Lithium Coin Cell Limits

The lithium chemistry provides the steady low current required for CMOS memory retention over long periods. It cannot supply power for system operation or charging circuits. The cell is a single-use component designed for motherboard solder points or a dedicated holder. Buyers who need a rechargeable main battery or a higher-capacity power source should look elsewhere.

Tested Replacement Unit

Each battery is tested before shipping to verify voltage and readiness for installation. The package includes one CMOS battery without additional tools or cables. Its compact form fits the M11x R3 motherboard layout, allowing straightforward replacement of a faulty or depleted original cell. No mounting hardware or wiring adapters are supplied.

Questions about this item

Which DBTLAP CMOS battery version fits my Dell Alienware M11x R3?

This single lithium CMOS battery is built specifically for the Dell Alienware M11x R3 motherboard and ships as a direct replacement unit.

What does the lithium chemistry mean once the battery is installed in my laptop?

The lithium cell keeps the real-time clock and BIOS settings alive when the main power is off, so the system remembers time and boot configuration across shutdowns.

What interface does this CMOS battery use and what does that limit in practice?

It connects via the standard two-pin motherboard header, so installation is a simple plug-in and the only limitation is physical access to that socket.
