Dell XPS 13 9343 CMOS replacement

This lithium coin cell restores the real-time clock and BIOS settings on a Dell XPS 13 9343 motherboard. It is intended for owners of that specific model who are experiencing time drift or CMOS checksum errors. The part is not a main laptop battery and will not power the system.

Fits the motherboard coin-cell holder

The battery slots directly into the existing CMOS socket on the board, requiring no cables or adapters. It frees the user from re-entering BIOS configuration after every cold boot. Installation only needs access to the motherboard, so the laptop must be partially disassembled.

Single tested cell in the pack

The package includes one pre-tested lithium CMOS battery, eliminating the guesswork of sourcing a generic equivalent. No software, drivers or additional hardware are bundled. The cell is ready to install once the chassis is open.
