Replacement CMOS Battery for Toshiba Z930-13N

This lithium coin cell replaces the CMOS BIOS RTC battery on the motherboard of the Toshiba Z930-13N laptop. It is not a main laptop battery and will not power the system. The part is supplied new and tested before shipping. Buyers needing a main power pack should look elsewhere.

Low Power Thermal Profile

The battery draws negligible current and produces no measurable heat or noise during normal operation. It maintains real-time clock and BIOS settings when the laptop is unplugged or powered off. Power consumption is effectively zero for system thermal budgets.

Simple Two-Wire Installation

The unit arrives as a single cell with a connector ready for the motherboard header. Replacement requires opening the chassis to access the board, so basic disassembly skill is needed. No drivers, cables or mounting hardware are included beyond the cell itself.

Highlights

  • Compatible replacement for Toshiba Z930-13N systems
  • Lithium chemistry provides reliable RTC power retention
  • Single battery included for direct motherboard installation
  • Pre-tested unit ensures dependable BIOS clock function

Questions about this item

How do I install this CMOS battery in my Toshiba Z930-13N and what step is often missed?

Open the chassis, locate the coin-cell holder on the motherboard, remove the old cell, and insert the new lithium unit with the correct polarity; the step often missed is reseating the connector firmly so the BIOS retains settings.

What maintenance or replacement will this CMOS battery need later?

The lithium cell will eventually deplete; when the system clock drifts or BIOS settings reset after shutdown, replace the battery with an identical coin-cell unit.

What limit appears first under sustained use?

The cell voltage gradually falls until it can no longer keep the real-time clock and CMOS memory powered while the laptop is off.
