Direct replacement for Sony VAIO VGN-AW41MF

This CMOS battery is built to fit the Sony VAIO VGN-AW41MF motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The part is intended for technicians or owners repairing that specific model.

Lithium coin cell limits

The lithium chemistry holds charge for years but cannot be recharged. It only powers the firmware clock and CMOS memory, not the main system. Once depleted the board loses date, time and boot configuration until the cell is swapped.

Simple two-wire installation

The battery arrives tested and ready to fit the existing connector on the motherboard. Polarity must match the original orientation or the board will not retain settings. No soldering is required, but forcing the connector the wrong way can damage the header.
