Product identity

This Rome Tech CMOS battery replaces the original BIOS backup cell in compatible Dell Alienware laptops including the M11x R1 R2, Area-51 13 15 17 18 R2 R3 R4, M14x R1 R2, M17x, M18x R2, Area-51 M9700 and M9750 models. It is intended for owners who need to restore system time and BIOS settings after the factory cell fails.

Thermals noise power

The CR2032 lithium coin cell operates at 3 V with negligible current draw so it produces no audible noise and no measurable heat during normal operation. Power consumption is limited to the microampere-level leakage required to maintain the real-time clock and CMOS memory.

Bundle impact

The package includes a pre-fitted 2-pin 2-wire cable and heat-shrink insulation so the battery connects directly to the motherboard header without soldering or modification. An identification label allows quick authenticity verification and the cell retains usable charge for up to 10 years in storage.

Questions about this item

How do I install the Rome Tech CMOS battery with its 2-pin cable on my Alienware M17x, and what step do people often miss?

Plug the 2-pin connector into the motherboard header, secure the CR2032 cell in its holder, and verify the BIOS clock holds time after the first cold boot — that final check is the step most skip.

What maintenance or replacement will this CR2032 CMOS battery need later?

The lithium coin cell holds charge for up to 10 years in storage; once installed, expect several years of service before the system clock drifts and the cell needs swapping.

What limit appears first when this CMOS battery runs continuously in an Alienware M18x R2?

The 3 V CR2032 cell gradually depletes; the first sign is the real-time clock losing time or BIOS settings resetting after the laptop sits unplugged for a few days.
