Direct replacement for Acer Aspire 7535G

This lithium CMOS battery is a direct replacement for the Acer Aspire 7535G laptop. It restores the real-time clock and BIOS settings when the original cell fails. The part is new and tested before shipping. It is designed for motherboard use only, not as a main laptop battery.

Single battery restores BIOS function

The package includes one CMOS battery ready for installation. No additional cables, adapters or software are supplied. Replacing the depleted cell immediately returns the system clock and firmware configuration to normal operation. The component is a simple hardware swap with no further setup required.

Maintains RTC and CMOS data reliably

The lithium chemistry provides stable voltage for the real-time clock and CMOS memory. It comfortably handles the low continuous draw of the motherboard circuitry. The battery will eventually deplete after several years of service, requiring another replacement to prevent time and settings loss.

Questions about this item

How often will the lithium CMOS battery in the Acer Aspire 7535G need replacement?

The lithium CMOS battery typically lasts several years; replace it when the system loses date, time or BIOS settings after power-off.

What is the first sign that the CMOS battery is failing during continuous operation?

The first limit appears as corrupted BIOS settings or a checksum error on boot, not during active runtime.

Does the CMOS battery generate any noise, heat or measurable power draw while the laptop runs all day?

No, the coin cell is passive, silent and draws negligible current only when the main power is off.
