Compatible Toshiba Satellite M105-S3084 CMOS Battery

This lithium CMOS RTC battery is designed for the Toshiba Satellite M105-S3084 laptop motherboard. It replaces the original BIOS backup cell that maintains system time and firmware settings when the main power is off. The part is supplied new and tested before shipping. It is not a main laptop battery and will not power the system for portable use.

Simple Solder-Free Replacement

Installation typically involves opening the laptop chassis, locating the coin-cell holder on the motherboard, and swapping the old cell for the new one. No soldering is required on most Satellite M105-S3084 units because the battery sits in a standard holder. The most common issue is forgetting to reset the BIOS date and time after the swap, which can cause boot errors until corrected.

Verify Motherboard Connector Before Ordering

Confirm that your Satellite M105-S3084 motherboard uses a removable coin-cell holder rather than a soldered-in cell, as layouts can vary by production batch. Check the existing battery voltage and physical diameter against the replacement to ensure a proper fit. This product is unsuitable for buyers who need a main rechargeable battery pack or a CMOS cell for a different laptop model.
