CMOS Battery for Sony VAIO VGN-BX61XN

This replacement CMOS battery is built for the Sony VAIO VGN-BX61XN laptop motherboard. It restores the system clock and BIOS settings when the original coin cell is exhausted. The lithium chemistry provides stable voltage for real-time clock circuitry. It is intended for owners of this specific model who need a direct replacement.

Single battery included in the package

The box contains one tested CMOS battery and nothing else. No tools, cables, adapters or software are bundled. Installers must reuse the existing connector and mounting method from the old cell. The lack of extras keeps the package minimal and focused on the single repair task.

Limited to motherboards using this exact coin-cell

The battery only fits boards that accept the same physical size and connector as the original VGN-BX61XN unit. It cannot power the main laptop load or replace a failed main battery pack. Systems with soldered-in RTC cells or different pinouts will not accept it. Buyers must verify the motherboard layout before ordering.

Questions about this item

When will the lithium CMOS battery need replacement in a Sony VAIO VGN-BX61XN?

The lithium CMOS battery typically lasts several years before the system clock drifts or BIOS settings reset, signalling it is time for a new one.

What is the first limitation when the CMOS battery runs continuously in a Sony VAIO VGN-BX61XN?

The first limit is voltage drop; once the cell can no longer hold 3 V the real-time clock stops keeping accurate time.

Does the CMOS battery generate noticeable heat or noise during all-day operation in a Sony VAIO VGN-BX61XN?

No, the coin cell draws microamps, so it produces no audible noise and no perceptible heat inside the laptop chassis.
