Compatible CMOS Battery for Aspire 7741

This lithium CMOS RTC battery is designed as a direct replacement for the Acer Aspire 7741Z-4643 laptop motherboard. It restores the real-time clock and BIOS settings when the original cell has failed. The part is supplied new and tested before shipping.

Fits Motherboard Slot to Restore BIOS

The battery installs into the standard CMOS holder on the laptop motherboard, not the main power battery bay. Replacing a faulty unit frees the system from date resets, checksum errors and boot failures caused by a depleted RTC cell. No soldering or additional tools are required for the swap.

Single Battery Included in Package

The package includes one CMOS battery only, letting you replace the exact component that has failed without buying a full motherboard kit. Each cell is verified before dispatch so it arrives ready to fit and hold the firmware configuration immediately.

Questions about this item

How long will the lithium CMOS battery keep the real-time clock running before it needs replacement?

The lithium cell maintains the BIOS clock for several years under normal use; actual lifespan depends on how often the Acer Aspire 7741Z-4643 is left unplugged.

Does the battery generate noticeable heat or noise during continuous operation?

No, a CMOS RTC battery is a passive component that produces no heat or noise while the laptop runs all day.

What must the laptop already have for this replacement to work?

The motherboard must include a standard two-pin CMOS header that matches the original battery connector on the Acer Aspire 7741Z-4643.
