  • Restores BIOS settings retention after old battery fails
  • Single lithium battery replaces faulty CMOS unit cleanly

CMOS battery for Acer TravelMate 5623

This lithium CMOS battery replaces the BIOS RTC cell on Acer TravelMate 5623WSMi laptop motherboards. It restores system clock and BIOS settings when the original battery fails. The unit is tested before shipping and arrives new. It is not a main laptop power battery.

Thermals noise and power draw

As a passive coin cell the battery generates no heat and makes no sound during normal operation. It draws negligible current to maintain the real-time clock and CMOS memory. No active cooling or power management is required. The component simply sits on the motherboard.

Behaviour under sustained load

The cell provides a steady low-voltage supply for years of continuous time-keeping duty. Voltage remains stable throughout its rated lifespan without sudden drops. There is no performance degradation during extended use. Builders needing a rechargeable main battery or higher capacity cell should look elsewhere.

Questions about this item

How do I install the CMOS battery in my Acer TravelMate 5623, and which step is often done incorrectly?

Open the laptop case, locate the coin cell on the motherboard, unplug its two-pin connector, and fit the new cell with the same polarity; the common mistake is reversing the connector or forcing it in upside-down.

What maintenance or replacement will this CMOS battery need later?

The lithium coin cell holds BIOS settings and the real-time clock; when the system clock drifts or settings reset after shutdown, replace the cell with another unit of the same type.

What limit appears first on the Acer TravelMate 5623 under sustained use?

The cell voltage gradually drops over years of continuous operation; once it falls below the threshold needed to keep the RTC running, the clock loses time and BIOS defaults reload at every boot.
