DBTLAP CMOS battery for Sony Vaio PCG-808

SKU CH-BZ7N-MC39J

A lithium CMOS battery that keeps the BIOS clock running on Sony Vaio PCG-808 laptops

  • Battery TypeLithium
  • Replaces the motherboard CMOS battery for Sony Vaio PCG-808
  • Keeps BIOS settings and system clock accurate with lithium cell
  • Tested before shipping to ensure reliable operation
  • Direct replacement for faulty or cracked original CMOS battery
  • Includes one new CMOS RTC battery ready to install

Compatible Sony Vaio PCG-808 CMOS battery

The DBTLAP lithium cell replaces the original BIOS RTC battery on Sony Vaio PCG-808 laptop motherboards. It restores system clock and firmware settings when the old unit fails. This part is not a main laptop battery and will not power the portable computer itself. Buyers needing a primary power pack should look elsewhere.

Low-draw lithium chemistry

The lithium cell supplies the tiny standby current required by the real-time clock and CMOS memory. Normal operation adds negligible heat and produces no audible noise. Power draw is far below levels that would affect the main power adapter or system thermals.

Single replacement cell included

The package contains one tested CMOS battery ready for installation. No cables, brackets, drivers or configuration utilities are supplied. The component is a direct swap for the original board-mounted cell and requires no additional software.

Questions about this item

How do I install the CMOS battery in the Sony Vaio PCG-808, and what step do people often get wrong?

Open the chassis, locate the coin-cell holder on the motherboard, remove the old cell noting the positive side orientation, press the new lithium cell in with the same polarity, then reassemble; the step most often missed is verifying the positive side faces the correct direction before closing the case.

What maintenance or replacement will this CMOS battery need later?

The lithium coin cell typically lasts several years; when the system clock starts losing time or BIOS settings reset after power-off, replace it with an identical CR-series coin cell.

What limit shows up first under sustained use of this CMOS battery?

The cell's finite capacity is the first limit; continuous very low current draw over years depletes it until voltage drops below the threshold needed to keep the real-time clock and CMOS memory alive.
