AA-PBUN2LT 7.6V 30Wh Samsung ATIV Book 9 Notebook 9 Battery — Manufacturer-Direct Stock

Q1: AA-PBUN2LT and AA-PBUN2QT both appear in parts databases — what distinguishes these two designations and which should be used as the reference P/N for procurement records?

A1: AA-PBUN2QT is a Samsung secondary designation for the same physical unit — same voltage, capacity, connector, cell configuration, and BMS architecture as AA-PBUN2LT. The two P/Ns appear in different regional documentation contexts: AA-PBUN2LT is the primary product identifier indexed across the majority of aftermarket parts databases and Samsung service documentation; AA-PBUN2QT appears in some regional distributor and Korean domestic market records. For procurement systems, AA-PBUN2LT should be used as the reference P/N. Orders placed under either designation draw from the same stock position.

Q2: Does the voltage specification differ between NP900X3L and NT900X3L / NT901X3L devices, or is 7.6V consistent across the full 900X3L generation?

A2: 7.6V is consistent across the full 900X3L device generation — NP900X3L US retail variants, all NT900X3L Korean domestic variants, NT900K3A, NT900X3M, NT900X3P, and the entire NT901X3L sub-model roster all use the same 7.6V specification. No voltage variant exists within this P/N family. Procurement teams sourcing batteries against a mixed US and Korean Notebook 9 fleet do not need to verify voltage per device suffix — AA-PBUN2LT at 7.6V applies uniformly across the full series.

Q3: Does AA-PBUN2LT cover NT900K3A? This designation appears in some asset management systems but is absent from many parts channel listings.

A3: NT900K3A is confirmed compatible with AA-PBUN2LT. It is a Korean domestic Samsung Notebook 9 chassis variant — same battery bay, connector, and charge profile as the NP900X3L — sold under a distinct Korean market designation that some aftermarket parts databases omit from their cross-reference tables. Sub-model variants NT900K3A-K34D, NT900K3A-K34M, NT900K3A-K35M, NT900K3A-K38L, NT900K3A-K38W, and NT900K3AI are all confirmed against AA-PBUN2LT. Procurement teams with NT900K3A device records can order AA-PBUN2LT directly without a separate compatibility qualification step.

Q4: After installing AA-PBUN2LT in an NT900X3L, the system charges normally but reports 0% capacity after a full charge cycle. What is the cause?

A4: A 0% reading after a full charge cycle on the 900X3L platform indicates the embedded controller’s state-of-charge register has not been reset following the previous battery’s removal. The EC on this chassis logs the prior pack’s last known SOC and may not overwrite it until a complete discharge-to-zero calibration event occurs. To resolve: allow the battery to discharge fully under normal use until the device powers off automatically, then charge uninterrupted to 100% without interruption. The EC updates the capacity register at the end of the first complete cycle. If the reading remains at 0% after two full cycles, perform an EC reset — power off, disconnect AC, hold power button for 20 seconds — before attempting a third calibration cycle.

Q5: As a factory-direct supplier, what is the ordering process for authorized service providers needing AA-PBUN2LT alongside other Samsung notebook battery lines?

A5: Ordering directly from the manufacturer, authorized service providers can combine AA-PBUN2LT with any other Samsung battery P/Ns in their replenishment cycle on a single consolidated order — no per-P/N order requirement, no series split. Submit the full P/N list with quantities; we return consolidated pricing in one quote. Low MOQ applies to the full Samsung order. For service accounts with recurring Notebook 9 replenishment cycles, standing order terms are available. Contact us with your parts list to begin.

Q6: The NT901X3L series has an unusually large number of sub-model suffixes — over 60 identifiers. Does AA-PBUN2LT cover all of them, or are certain suffix variants excluded?

A6: All NT901X3L sub-model variants confirmed in parts databases are covered by AA-PBUN2LT. The large sub-model roster reflects Samsung’s Korean domestic distribution model, where the NT901X3L was sold through multiple carrier channels and configuration tiers — each generating a distinct suffix — without any change to the underlying chassis or battery specification. The /C and /R suffix designations indicate channel variant, not a hardware difference. No NT901X3L sub-model within the 900X3L-generation battery platform requires a different P/N.
