Compatible Dell Alienware M18x R2 CMOS Battery

This lithium CMOS battery is designed for the Dell Alienware M18x R2 laptop motherboard. It replaces the original BIOS RTC battery that maintains system time and firmware settings. The unit is intended for owners of that specific model who need a direct replacement. It is not a main laptop power battery and will not suit other Alienware chassis or different brands.

Tested Lithium Cell Build

Each battery is tested before shipping to confirm reliable voltage output for real-time clock operation. The lithium chemistry provides stable long-term performance on the motherboard without requiring recharging from the main power system. Installation follows the standard motherboard coin-cell socket, so no soldering or special tools are needed during replacement. Builders working on unrelated laptop models or desktop boards should verify compatibility before purchase.

Single Battery Package

The package includes one CMOS battery only, with no additional cables, brackets or software utilities. This keeps the kit minimal for technicians who already have opening tools and thermal paste on hand. Users expecting a full laptop battery pack, charger or driver disc will not find them here. The single-unit pack is suited for one-time motherboard maintenance rather than bulk servicing.
