Dell XPS 1820 CMOS Battery

This lithium coin cell replaces the BIOS real-time clock battery on Dell XPS 1820 laptop motherboards. It restores system time, date and firmware settings after the original cell is exhausted. The part is intended for owners of that specific model who need a direct replacement.

Lithium coin cell limits

A single lithium cell delivers a fixed 3 V output and cannot be recharged. Capacity diminishes slowly over several years, so the battery must be replaced once the system clock drifts or BIOS settings are lost at power-off. No charging circuit or higher-voltage alternative is supported by the motherboard.

Dell XPS 1820 compatibility

The battery is built to fit the Dell XPS 1820 motherboard holder and connector. It will not suit other Dell models or any desktop boards that use a different form factor or pin layout. Buyers with a different laptop series must source the correct part for their machine.
