Compatible CMOS Battery for Sony VAIO VGN-FS660/W

This lithium CMOS battery replaces the original BIOS RTC cell on the Sony VAIO VGN-FS660/W motherboard. It restores system time and BIOS settings when the old cell fails. The part is supplied new and tested before shipping. It is not a main laptop battery and will not power the system.

Simple Motherboard Installation

Replacing the CMOS battery requires opening the laptop chassis to reach the motherboard socket. The cell plugs directly into the board without soldering. Care is needed to avoid damaging the connector or surrounding components during removal and insertion. No software configuration is required after fitting.

Lithium Cell Limitations

The lithium chemistry provides long shelf life but will eventually discharge over several years of continuous use. It maintains only the real-time clock and CMOS memory, not main system power. The battery is specific to the listed Sony model and is not interchangeable with other VAIO series or brands.
