Direct replacement for Sony Vaio VGN-FE11S

This lithium CMOS battery is built specifically for the Sony Vaio VGN-FE11S motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The part is new and tested before it leaves the supplier. It is not a main laptop battery and will not power the system.

Limited to RTC and BIOS retention

The cell only maintains the system clock and firmware configuration while the laptop is off. It cannot supply power to any other component or charge the main battery. If the computer loses time or shows CMOS checksum errors, this battery addresses that specific fault. It does not fix boot failures caused by other hardware.

Simple two-wire connector swap

Installation requires opening the chassis, unplugging the old two-wire connector and fitting the new one in the same socket. Polarity must match the original or the board will not recognise the cell. The most common issue is routing the short cable without straining the header pins. No soldering or software configuration is needed.
