DBTLAP CMOS Battery for Sony VAIO VGN-Z48GD/X

SKU CH-9S2B-QGHQG

Replacement CMOS BIOS battery keeps system clock and settings for Sony VAIO VGN-Z48GD/X laptops

  • Battery TypeLithium
  • Direct replacement for Sony VAIO VGN-Z48GD/X
  • Lithium chemistry provides stable BIOS power
  • Pre-tested unit ensures reliable startup
  • Single battery replaces faulty CMOS cell
  • New condition guarantees full service life

Compatible CMOS Battery

The DBTLAP CMOS battery is a direct replacement for the Sony VAIO VGN-Z48GD/X motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The lithium chemistry provides the stable voltage required for low-power memory retention. This part is intended for technicians or owners servicing this specific notebook model.

Installation and Fit

The battery installs on the system board to maintain CMOS data while the main power is disconnected. It frees the user from repeated BIOS resets and system time errors caused by a depleted cell. The package includes one tested unit ready for soldering or connector attachment as required by the board layout. No additional components are needed to complete the repair.

Sustained Reliability

Under continuous standby duty the lithium cell delivers a steady voltage for long-term CMOS retention. It is tested before shipping to verify capacity and leak-free construction. The chemistry resists self-discharge during extended periods when the laptop is unplugged. Buyers needing a main power pack or a higher-capacity backup cell should look elsewhere.

Highlights

  • Direct replacement for Sony VAIO VGN-Z48GD/X
  • Lithium chemistry provides stable BIOS power
  • Pre-tested unit ensures reliable startup
  • Single battery replaces faulty CMOS cell
  • New condition guarantees full service life

Questions about this item

How long will the lithium CMOS battery keep the system clock running under continuous use?

The lithium cell is rated to maintain BIOS settings and the real-time clock for several years of continuous operation before replacement is needed.

Does the battery generate noticeable heat or noise during all-day operation?

No, the passive lithium cell produces no audible noise and negligible heat while powering the CMOS circuitry.

What connector or cable must the motherboard already have for this battery to work?

The board must provide a standard two-pin CMOS header that matches the battery’s lead spacing.
