Compatible CMOS battery for Sony Vaio PCG-FR720

This lithium CMOS battery is designed for the Sony Vaio PCG-FR720 laptop motherboard. It replaces the original BIOS RTC cell that keeps system time and firmware settings when the main power is off. The unit is tested before shipping to confirm reliable operation. It is intended for laptop motherboards, not for the main laptop battery pack.

Lithium coin cell with solder-ready leads

The battery uses a standard lithium chemistry in a coin-cell format with attached leads for direct motherboard connection. Build quality focuses on a secure solder joint and stable voltage output over the service life. Installing it requires opening the chassis and basic soldering skill, so it suits technicians or experienced hobbyists rather than casual users seeking a tool-free swap.

Single replacement cell in protective packaging

The package includes one CMOS battery sealed for transit protection. No additional cables, brackets, or configuration software are supplied. The sole accessory is the cell itself, meaning the buyer must provide any necessary tools and thermal management materials. This keeps the kit minimal for straightforward motherboard maintenance.
