CMOS Backup Battery for Dell Alienware Laptops

This 3.0 V lithium cell replaces the CMOS battery in Dell Alienware M11X, M11X R1, M11X R2, M14X, M15X, M17x, M18x and M9750 models. It supplies the low current needed to retain BIOS settings and system time when the main power is disconnected. The green-wrapped unit is a direct replacement for the original P06T part.

Non-rechargeable lithium cell with wire leads

The battery uses primary lithium chemistry rated at 0.2 Ah and 0.60 Wh, so it cannot be recharged by the laptop. Its compact 25.20 x 20.32 x 4.80 mm footprint fits the motherboard holder without modification. Attached leads connect to the existing header, allowing a straightforward swap without soldering.

3.0 V 0.2 Ah capacity determines suitability

This voltage and capacity match the original specification for the listed Alienware notebooks. Buyers whose systems require a different voltage or a higher milliampere-hour rating will need an alternative part. The cell is intended solely for CMOS backup duty and cannot power the main laptop.
