DBTLAP CMOS Battery for TOSHIBA Libretto 100CT

SKU CH-NM46-WK0GD

Replacement CMOS RTC battery for the Toshiba Libretto 100CT motherboard, tested before shipping

  • Battery TypeLithium
  • Lithium chemistry provides stable RTC power
  • Tested before shipping to ensure reliable operation
  • Replaces faulty or cracked CMOS batteries
  • Designed for TOSHIBA Libretto 100CT motherboards
  • Package includes one CMOS RTC battery

Purpose-built replacement

This CMOS battery restores real-time clock and BIOS settings on a Toshiba Libretto 100CT. It is a direct-fit lithium cell for the motherboard, not a main laptop battery. Owners of this specific legacy sub-notebook can revive date retention and boot configuration without soldering or adapter cables.

Thermals, noise and power

As a passive coin cell, the battery generates no heat and makes no sound during normal operation. Current draw is in the microampere range, so it has no measurable impact on system power consumption or chassis temperature. The lithium chemistry maintains stable voltage across the operating envelope of the original hardware.

What the bundle changes

The package includes one pre-tested CMOS RTC battery, eliminating the need to source loose cells or verify voltage manually. Immediate installation returns the Libretto 100CT to reliable time-keeping and CMOS checksum integrity. No additional software, drivers or configuration tools are required or supplied.

Highlights

  • Lithium chemistry provides stable RTC power
  • Tested before shipping to ensure reliable operation
  • Replaces faulty or cracked CMOS batteries
  • Designed for TOSHIBA Libretto 100CT motherboards
  • Package includes one CMOS RTC battery

Questions about this item

How do I install this CMOS battery in a Libretto 100CT, and what step do people often miss?

Open the chassis, locate the coin-cell holder on the motherboard, remove the old cell, insert the new lithium cell with the positive side facing up, then reassemble; the step often missed is entering BIOS afterwards to reset the date and time.

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 revert at boot, replace the cell with an identical CR-series coin battery.

What limit appears first during sustained use of this CMOS battery?

The shelf-life and discharge curve of the lithium chemistry set the practical limit; after multiple years the voltage drops below the threshold needed to keep the real-time clock and CMOS memory alive.
