DBTLAP CMOS Battery for Toshiba NB100-128

SKU CH-ZDX5-FAWAF

Lithium CMOS battery replaces the BIOS clock cell on Toshiba NB100-128 laptops

  • Battery TypeLithium
  • Keeps system time accurate with lithium CMOS cell
  • Direct replacement for Toshiba NB100-128 motherboard battery
  • Restores BIOS settings after faulty cell failure
  • Pre-tested unit ensures reliable first boot

Direct replacement for NB100-128

This lithium CMOS battery is built specifically for the Toshiba NB100-128 motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The part is new and intended for laptop motherboard repair, not for the main laptop battery compartment.

Single battery in the package

The box contains one CMOS battery that has been tested before shipping. No cables, brackets or software are included, so the installer only needs the battery itself and basic tools to complete the swap.

Lithium cell with standard connector

The lithium chemistry provides stable voltage for long-term CMOS retention. The connector matches the NB100-128 motherboard header, allowing a direct fit without soldering or adapter cables. Build quality is focused on reliable contact retention through repeated thermal cycles.

Questions about this item

How often will the lithium CMOS battery in my NB100-128 need replacement?

The lithium cell typically holds BIOS settings for several years; replace it when the system clock drifts or CMOS checksum errors appear at boot.

What is the first sign that the CMOS battery is failing under continuous operation?

The first limit is voltage drop — the real-time clock loses time or BIOS settings reset after the laptop has been off for a while.

Does the replacement CMOS battery generate any noticeable heat or noise during all-day use?

No, the coin cell is passive; it produces no audible noise and negligible heat while maintaining the RTC and CMOS memory.
