Compatible CMOS Battery for Satellite Pro P100-305

This replacement CMOS battery is designed for the Toshiba Satellite Pro P100-305 laptop. It restores the system clock and BIOS settings when the original cell fails. The part is intended for repair technicians or owners maintaining this specific legacy model. It is not a main laptop battery and will not power the device for portable use.

Lithium Coin Cell Chemistry

The battery uses a standard lithium chemistry to provide the low, steady voltage required by the motherboard RTC circuit. This specification determines whether the cell matches the original electrical requirements of the P100-305 platform. Buyers needing a rechargeable main power pack or a different voltage format should look elsewhere.

Direct Motherboard Installation

The unit arrives as a single tested cell ready for direct placement on the motherboard. Installation requires opening the laptop chassis to access the CMOS socket or solder pads. The process demands careful disassembly and static precautions; incorrect polarity or physical damage during fitting are the typical failure points.
