Replacement CMOS Battery for Satellite P100-354

This lithium CMOS battery replaces the original BIOS RTC cell on a Toshiba Satellite P100-354 motherboard. It restores system clock and BIOS settings when the old cell fails. The part is supplied new and tested before shipping. It is not a main laptop battery.

Simple motherboard installation

Fitting the battery requires opening the laptop case and locating the CMOS socket on the motherboard. The connector plugs in directly with no soldering. The main risk is damaging the fragile socket or cable during removal of the old cell. Take care to match the polarity when inserting the new unit.

Lithium chemistry ensures correct voltage

The lithium cell provides the stable voltage the motherboard needs to keep the real-time clock running while the laptop is off. Buyers who need a main power battery or a different form factor cannot use this part.
