Compatible Samsung 900X4 series replacement

The Beisite AA-PBXN8AR is a 7.4V 62Wh lithium-ion battery built to fit Samsung 900X4 and NP900X4 ultraportables. It replaces the original AA-PBXN8AR part number across a wide range of sub-models. The black pack ships as a single unit ready for installation.

Upgrading from a depleted or swollen pack

When the original cell no longer holds a useful charge or shows physical swelling, this new 62Wh unit restores the factory runtime specification. The jump is worth it if your laptop now shuts down early, runs only on mains power or reports a battery health warning in the OS.

Verify the exact model label before ordering

Check the sticker on the bottom of your Samsung laptop for one of the listed model numbers such as 900X46, 900X4B-A02 or NP900X4C-A01US. Confirm the original battery carries the AA-PBXN8AR part number and uses a 7.4V lithium-ion pack. This battery does not suit other Samsung series or higher-voltage designs.

Questions about this item

Does the AA-PBXN8AR fit the Samsung 900X4B-A02US chassis and connector?

What is the common mistake when installing this 7.4V battery?

Forgetting to disconnect the old battery cable before removing the bottom cover can cause a short; always unplug the connector first.
