Replacement battery for Acer Aspire One 531 751

This Cameron Sino DS-CS-ACZG7NK lithium-ion battery is built for Acer Aspire One 531 and 751 models including the 751h variants. It serves owners of these netbooks who need a new power source after the original cell has degraded. The black pack fits the existing battery bay without modification.

Capacity and daily runtime

Rated at 2.2 Ah the pack delivers enough energy for typical web browsing and document work on these low-power netbooks. Runtime will shorten under heavier loads such as video playback or when the screen brightness is kept high. The capacity matches the original specification so users can expect similar endurance to a fresh factory battery.

Limits of the original battery interface

The cell connects through the proprietary connector used by the Aspire One 531 and 751 families. It cannot be used in other Acer lines or in laptops from different brands because the pin layout and voltage regulation are model specific. Buyers with multiple netbook generations should verify the exact model number before ordering.

Questions about this item

Will the 2.2 Ah DS-CS-ACZG7NK fit my original Acer Aspire One 531 chassis without modification?

Yes, the battery is built to the same form factor as the original UM09A31 and UM09B31 packs used in the Aspire One 531 and 751 series.

How can I confirm the DS-CS-ACZG7NK is charging correctly after I install it?

The Acer power LED will show amber while charging and turn blue at full charge; the OS battery meter should report a 2.2 Ah design capacity.

Does the DS-CS-ACZG7NK package include a replacement AC adapter or only the battery?

Only the lithium-ion battery is supplied; the original AC adapter must be reused or purchased separately.
