15.4V 54Wh 4-cell Li-ion replacement battery

This 15.4V 54Wh 4-cell lithium-ion battery replaces the original power pack in compatible Samsung Notebook 9 Pen, Notebook Pen S, Galaxy Book Flex Alpha, Galaxy Book Flex2 Alpha and Galaxy Book models. It restores mobile runtime for professionals and students who rely on these ultraportables for daily work.

Verify the exact model number before ordering

Check the label on your existing battery or the laptop’s service tag against the long compatibility list supplied with this part. The same chassis was used across several regional SKUs and only the listed part numbers are confirmed to fit; installing this unit in an unlisted variant can prevent the laptop from recognising the pack.

Drop-in fit for the listed Samsung ultraportables

The battery slots into the internal bay without adapters or cable modifications, freeing the USB-C charging port for peripherals or external displays. It is not suitable for laptops outside the named series, for devices that require a different voltage or cell count, or for users who need a higher-capacity pack than the 54Wh rating provides.

Questions about this item

Does the PISKEKAT AA-PBSN4AF battery ship with installation tools or must they be purchased separately?

The battery is supplied as a standalone unit; no screwdrivers, opening picks or adhesive strips are included, so any tools required for the swap have to be sourced separately.

How do I confirm which 15.4 V 54 Wh 4-cell version matches my Samsung Notebook 9 Pen NP930SBE-K02HK?

Match the exact model suffix — NP930SBE-K02HK appears in the compatible list, so this 15.4 V 54 Wh 4-cell pack is the correct replacement for that unit.

What does the 54 Wh rating mean for daily runtime on a Galaxy Book Flex Alpha NP730QCJ-K01US?

At 54 Wh the pack stores the same energy as the original Samsung battery, delivering comparable hours per charge under identical workload and brightness settings.
