Direct replacement for Dell XPS L401X

This lithium CMOS battery replaces the BIOS RTC cell on the Dell XPS L401X motherboard. It restores the system clock and firmware settings when the original cell has failed. The part is supplied new and tested before shipping. It is not a main laptop battery and does not power the system.

Fits the motherboard battery holder

The cell slots into the existing CMOS socket on the board, requiring no soldering or adapter cables. Installation frees the firmware from time drift and checksum errors caused by a depleted coin cell. No additional power components or configuration changes are needed.

Upgrades from a dead or leaking original cell

The jump is worth it when the laptop loses date, time or BIOS settings after each shutdown. Builders who need a rechargeable main battery or a different form factor cannot use this part. It addresses only the real-time clock supply on the specified model.
