DBTLAP CMOS Battery for Sony Vaio

This DBTLAP lithium CMOS battery is a direct replacement for the Sony Vaio VGN-FJ170/B laptop motherboard. It restores BIOS settings and real-time clock function when the original cell fails. The part is intended for technicians or owners servicing this specific notebook model. It is not a main laptop battery and will not power the system.

Tested replacement restores BIOS operation

Each unit is tested before shipping to confirm reliable voltage delivery for CMOS memory retention. The battery comfortably handles standard RTC and configuration storage duties for the target platform. It runs out when the lithium chemistry depletes after several years of continuous service, requiring another swap.

Low-drain design produces no heat or noise

As a passive lithium cell, the battery draws negligible current and generates no measurable heat during normal operation. It operates silently with zero moving parts and adds no load to the laptop power system. Installation is a simple motherboard socket exchange.
