CMOS battery for ASUS ZenBook UX32A

This lithium CMOS battery replaces the original BIOS RTC cell on the motherboard of an ASUS ZenBook UX32A. It is intended for owners whose system clock resets or who receive CMOS checksum errors at boot. The part is not a main laptop battery and will not power the device itself. Buyers who need a primary power pack should look elsewhere.

Thermals noise and power draw

As a passive coin cell the battery generates no heat and makes no sound during normal operation. Its current draw is in the microampere range so it has no measurable effect on system power consumption or battery life. No active cooling or ventilation is required for this component.

Bundled accessory

The package includes a single replacement CMOS battery that has been tested before shipping. No cables, brackets, tools or software are supplied. The only change after installation is restored BIOS timekeeping and settings retention.

Highlights

  • Compatible with ASUS ZenBook UX32A motherboards

Questions about this item

How do I install the CMOS battery in the ASUS ZenBook UX32A and what step is often missed?

Remove the bottom case, disconnect the main battery first, then swap the coin cell on the motherboard; the step often missed is reconnecting the main battery before closing the chassis.

What maintenance or replacement will this lithium CMOS battery need later?

The lithium coin cell typically lasts several years; replace it when the system loses date and time settings after being powered off.

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

The 3 V lithium chemistry gradually loses capacity, so the first limit is voltage drop below the level needed to keep the real-time clock running.
