Compatible Dell Studio 1558 CMOS Battery

This lithium coin cell replaces the BIOS RTC battery on Dell Studio 1558 motherboards. It restores system time and firmware settings when the original cell fails. The part is intended for laptop motherboard maintenance, not for the main laptop battery.

Tested Lithium Coin Cell

Each unit is tested before shipping to confirm reliable voltage output. The bare cell design matches the original motherboard mounting style used in the target model. Installation requires opening the laptop chassis and accessing the board directly.

Single Replacement Unit Included

The package contains one CMOS battery only, with no cables, holders or tools supplied. No software or drivers are involved because the component is a passive hardware part. Buyers needing a main laptop battery or a multi-cell pack should look elsewhere.
