SKU CH-QTBY-W0YH8

Lithium CMOS battery replaces the BIOS RTC cell on Toshiba NB100-12M motherboards

  • Battery TypeLithium
  • Keeps BIOS settings and system clock accurate
  • Lithium cell provides reliable long-term power
  • Direct replacement for the original CMOS battery
  • Tested before shipping to ensure proper function
  • Single battery included for immediate installation

Direct replacement CMOS battery

This lithium CMOS battery is designed as a direct replacement for the Toshiba NB100-12M motherboard. It restores BIOS settings and real-time clock function when the original cell is exhausted. The part is supplied new and tested before shipping. Builders repairing this specific model will find it a straightforward swap.

Compatibility limited to NB100-12M

The single specification that decides fitment is the exact model match to the Toshiba NB100-12M. It is not a main laptop power battery and will not power the system. Buyers with any other laptop series or motherboard revision cannot use this component. Verify the service manual before ordering.

Steady low-current retention

Under sustained load the cell delivers the microamp-level current required to keep CMOS memory alive for years. It does not face high-drain cycles, so capacity fade is gradual and predictable. The lithium chemistry holds voltage stably across the operating temperature range of the motherboard. No sudden failure spikes are typical.

Highlights

  • Keeps BIOS settings and system clock accurate
  • Lithium cell provides reliable long-term power
  • Direct replacement for the original CMOS battery
  • Tested before shipping to ensure proper function

Questions about this item

Will this lithium CMOS battery keep the clock and BIOS settings alive once installed in my NB100-12M?

Yes, it supplies the 3 V needed by the motherboard RTC so the system retains time, date and firmware configuration when the main power is removed.

What connector standard does this replacement use to attach to the board?

It uses the same two-pin header layout as the original factory module, so it plugs straight into the existing socket without adapters.

What physical space does the battery need inside the NB100-12M chassis?

The cell is a standard coin-format unit measuring 12 mm across, matching the compartment designed for the original part.
