Compatible CMOS battery for Acer Aspire 4741G

This lithium CMOS battery replaces the BIOS RTC cell on Acer Aspire 4741G laptop motherboards. It restores system time and BIOS settings when the original cell fails. The unit is tested before shipping and arrives new in a single-piece package.

Passive thermal profile and minimal power draw

The coin cell operates without active cooling and generates no audible noise during normal use. Its lithium chemistry provides a stable low-current supply to the real-time clock circuit. Power consumption is negligible and places no measurable load on the motherboard.

Direct replacement for a depleted motherboard cell

This part upgrades a laptop that loses the date, time or BIOS configuration after power loss. The jump is worth it when the existing CMOS battery no longer holds a charge. It is not for users who need a main laptop battery or a higher-capacity power source.

Questions about this item

How do I install this CMOS battery in an Acer Aspire 4741G and which step do people often get wrong?

Remove the old cell from its socket on the motherboard, note the orientation of the positive side, and press the new lithium battery in the same direction; the common mistake is inserting it backwards.

What maintenance or replacement will this CMOS battery need later?

The lithium cell typically holds BIOS settings for several years; when the clock drifts or settings reset at each boot, replace it with another compatible coin cell.

What limit shows up first under sustained use?

The internal chemistry degrades slowly, so the first sign of end-of-life is a system clock that loses time or BIOS defaults reloading after the laptop is powered off.
