CMOS battery for TravelMate 2480-2196

This lithium CMOS battery replaces the RTC cell on Acer TravelMate 2480-2196 motherboards. It restores BIOS clock and configuration retention when the original cell fails. The part is supplied new and tested before shipping. It is a motherboard battery, not a main laptop power pack.

Thermals noise and power draw

As a passive lithium 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. No active cooling or ventilation is required.

Upgrade context and value

This battery replaces a depleted or leaking CMOS cell that causes date reset and BIOS errors. The jump is worth it when the laptop loses time or settings after power loss. It does not add storage, memory or processing capability and is not for users needing a main system battery.

Questions about this item

How do I install this CMOS battery in my TravelMate 2480-2196, and what step is often missed?

Open the chassis, locate the coin cell on the motherboard, remove the old one, insert the new cell with the correct polarity, then enter the BIOS to reset the date and time.

What maintenance or replacement will this CMOS battery need later?

The lithium cell typically lasts several years; when the system clock drifts or BIOS settings clear at startup, replace it with another compatible CMOS battery.

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

The cell voltage gradually drops until it can no longer maintain the real-time clock and CMOS memory, causing time loss and configuration resets.
