Compatible CMOS Battery for Sony VAIO PCG-GRT270

This lithium CMOS battery replaces the BIOS RTC cell on the motherboard of the Sony VAIO PCG-GRT270 laptop. It restores system clock and BIOS settings when the original cell is exhausted. The unit is tested before shipping and supplied as a single replacement part.

Practical Limits of Lithium Coin-Cell Chemistry

Lithium coin cells provide stable low current for years but cannot be recharged and will eventually deplete. They operate within a narrow voltage window so polarity must be observed during installation. Extreme temperatures accelerate self-discharge and reduce service life.

Battery Type Lithium

The lithium chemistry determines the nominal voltage and physical footprint required by the motherboard. Only a matching lithium coin cell will maintain the real-time clock and CMOS memory correctly. Installing a different chemistry risks data loss or hardware damage.
