Compatible Laptop Models

This CMOS battery is built for the ACER AO751h-1709 laptop motherboard. It supplies the low-voltage power that keeps the real-time clock and BIOS settings active when the main battery is removed or depleted.

Battery Chemistry and Reliability

The cell uses lithium chemistry for stable voltage output and a long shelf life. Each unit is tested before shipping to confirm it holds a charge and fits the motherboard holder without modification.

Critical Fit Requirement

This part fits only the ACER AO751h-1709 motherboard; it will not work in other Acer models or desktop boards. Buyers who need a CMOS battery for a different laptop must verify the exact model number before ordering.

Questions about this item

How do I install this CMOS battery in the Acer AO751h-1709, and what step is often missed?

Open the chassis, unplug the old battery connector from the motherboard header, insert the new cell and reconnect it; the step often missed is forgetting to reseat the connector fully so the BIOS retains settings.

What maintenance or replacement will this lithium CMOS cell need later?

The cell requires no routine maintenance; when the system clock drifts or BIOS settings reset after shutdown, replace it with a new unit of the same type.

What limit appears first under sustained use?

The lithium chemistry gradually loses capacity; the first sign is loss of date and time or cleared BIOS settings when the laptop is unplugged.
