Product Description
The AA-PBTN4LR replacement battery covers the Samsung Notebook 9 Pro — a premium 13- and 15-inch platform that remains active across managed enterprise and education device pools in North America, with a disproportionately thin aftermarket supply relative to the installed device population. At 15.4V and 54Wh, this unit matches the OEM specification across the NP940X3M, NP940X5M, and NP940X5N series.
The Samsung Notebook 9 Pro battery compatibility footprint extends across two distinct naming conventions: the NP940X-series US retail designations and the NT-prefix Korean market identifiers — NT930SBE, NT930SBV, NT950QAA, NT950SBE, NT950SBV — that appear in procurement systems for institutions sourcing Samsung devices through regional distributors. Five cross-reference codes (AA-PBTN4LR-05, BA43-00386A, 4ICP5/43/97, 1588-3366) resolve to the same physical unit.
For procurement managers handling Samsung Notebook 9 Pro fleets that include both US-designated NP940X units and NT-prefix Korean-market variants, a single stock position under AA-PBTN4LR eliminates the ordering fragmentation that otherwise occurs when both naming conventions are treated as separate battery populations. One SKU satisfies incoming demand from both device cohorts, reducing the number of active purchase order lines against Samsung Notebook 9 Pro battery demand to one.

Features & Advantages
✅ 🔋 Replacement Interval Economics: What 54Wh Means Across a Four-Year Notebook 9 Pro Deployment
The NP940X3M and NP940X5M entered enterprise and education procurement in 2017–2018, placing most active units in a four- to six-year service window where battery replacement is expected once. A 500-cycle rating on a 54Wh unit — larger than most 13-inch premium platform batteries — means the energy delivered per cycle is higher, and the replacement interval consequence is direct: one battery swap per device covers the remainder of the typical service window without a second replacement event. For fleet accounts, that collapses a potential two-replacement lifecycle cost into a single per-unit line item.
✅ 🔁 NP940X3M, NP940X5M, NP940X5N, and Six NT-Series Designations Under One P/N
AA-PBTN4LR satisfies battery demand across the NP940X3M and NP940X3N 13-inch configurations, the NP940X5M and NP940X5N 15-inch configurations, and six NT-prefix Korean-market designations: NT930SBE, NT930SBV, NT950QAA, NT950SBE, NT950SBV, and NT850XBC. Cross-reference codes 4ICP5/43/97 and 1588-3366 resolve to the same stock position. For service accounts where NT-series device records appear alongside NP940X entries in the same asset management system, one replenishment order covers both populations.
✅ ⚡ Notebook 9 Pro EC Handshake: Failure Scenario, BMS Response, and Diagnostic Consequence
On the NP940X platform, the most common post-replacement failure scenario is a charge-circuit suspension that appears immediately after installation: the system powers on, AC is connected, but the battery indicator shows “plugged in, not charging.” This occurs when the embedded controller does not receive a valid BMS authentication response within the expected window after AC connection. The BMS on this unit delivers overcharge cutoff and short-circuit interrupt at the cell boundary first, then presents the authentication handshake to the EC — in the sequence the NP940X firmware expects. Over-discharge protection holds cell voltage above the threshold that triggers the EC’s non-recoverable fault state on this platform, preventing the condition where the battery is present but charge acceptance is permanently suspended until a firmware-level EC reset.
✅ 📦 Receiving and QC Workflow for Mixed Samsung Notebook 9 Pro and Notebook 9 Depot Stock
Service depots running receiving processes against multiple Samsung Notebook 9 P/Ns — including AA-PBTN4LR alongside adjacent lines covering Notebook 9 (non-Pro) and ATIV Book series — can consolidate inbound shipments under a single Samsung battery wholesale order. Each P/N ships from verified stock with batch documentation; receiving teams QC against a single spec sheet per P/N rather than managing separate supplier documentation per order event. Low MOQ applies across the combined Samsung battery line — no per-P/N order minimum enforced separately.
✅ 🌐 Cross-Brand Sourcing for Depots Servicing Samsung and Adjacent Premium Platforms
Repair depots servicing Samsung Notebook 9 Pro units alongside other premium-platform devices — HP EliteBook, Lenovo ThinkPad, or Dell Latitude lines — can place a single replenishment order combining AA-PBTN4LR with compatible P/Ns from those brands. This eliminates the sourcing friction of maintaining separate supplier relationships per OEM brand for battery stock, reducing the number of active vendor accounts a depot purchasing officer manages for a mixed-brand service contract. Cross-brand ordering is supported from stock with no brand-based order split required.

FAQ
1: AA-PBTN4LR and AA-PBTN4LR-05 both appear in parts databases — do these designate different production revisions, or are they the same unit?
A1: AA-PBTN4LR-05 is a Samsung internal revision suffix applied to the same physical battery unit — not a separate model. The connector, voltage, capacity, cell configuration, and BMS architecture are identical between AA-PBTN4LR and AA-PBTN4LR-05. Purchase orders and parts requests referencing either designation draw from the same stock position. For procurement systems that log the suffix variant separately, both identifiers should be consolidated to a single SKU line. This unit ships under AA-PBTN4LR as the primary P/N reference.
Q2: Some aftermarket sellers claim 14.8V and 15.4V are interchangeable for AA-PBTN4LR. Is this accurate?
A2: No. The NP940X platform’s charge management circuit is calibrated to 15.4V nominal. Installing a 14.8V-rated unit does not cause immediate hardware failure, but the charge profile delivered by a 14.8V cell pack runs outside the voltage window the NP940X power management subsystem is tuned for — resulting in incomplete charge cycles and accelerated capacity degradation over the first 50–80 cycles. All specialist parts databases and Samsung’s own documentation list AA-PBTN4LR exclusively at 15.4V. The interchangeability claim originates from seller listings that have not verified the platform-specific charge spec.
Q3: Does AA-PBTN4LR fit the NT-series designations — NT930SBE, NT950SBE, NT950SBV — or only the NP940X US models?
A3: NT-prefix designations are Samsung’s Korean domestic market identifiers for the same hardware generations as the NP940X-series US retail models. NT930SBE, NT930SBV, NT950QAA, NT950SBE, NT950SBV, NT850XBC, and NP850XBC are all confirmed compatible with AA-PBTN4LR. Procurement teams managing Samsung device pools that include Korean-market inventory — common in institutions that sourced devices through regional resellers — can order AA-PBTN4LR against NT-series asset records without a separate compatibility qualification step.
Q4: After replacing the battery in an NP940X5M, the laptop shows “plugged in, not charging” immediately on first boot. What is the cause and resolution?
A4: This is the most common post-installation symptom on the NP940X platform when the embedded controller has not cleared its session state from the previous battery. The EC retains charge-state data from the prior battery and may suspend the charge circuit if the new battery’s initial voltage reading falls outside the expected window. Resolution: shut down completely, disconnect AC, hold the power button for 15–20 seconds to discharge system capacitors, then reconnect AC without seating the battery. Boot to the OS on AC power only, then power off, seat the battery, and reconnect AC. On the next boot, the EC initializes a fresh battery session and charge resumes normally.
Q5: We need to replenish AA-PBTN4LR as part of a broader Samsung service contract that also covers Notebook 9 and ATIV Book models. Can all Samsung P/Ns ship on one order?
A5: Yes — the entire Samsung battery range covered under a service contract can be consolidated into a single replenishment order. Submit your full P/N list with quantities and we’ll return pricing across all lines in one quote. Low MOQ applies to the consolidated order without per-P/N minimums enforced separately. For purchasing officers managing standing Samsung service contracts, we can structure recurring order terms to simplify each replenishment cycle. Contact us with your parts list to initiate.
Q6: NT950QAA appears in some procurement records under a different battery P/N. Is AA-PBTN4LR confirmed for this model, or should a different unit be sourced?
A6: AA-PBTN4LR is confirmed for the NT950QAA across multiple parts databases and seller listings. The occasional reference to a different P/N against NT950QAA records originates from early aftermarket database entries that pre-date the wider cross-reference mapping for this model. The NT950QAA shares the same battery bay, connector, and charge management circuit as the NP940X5N — the reference hardware for AA-PBTN4LR. No separate unit is required for NT950QAA procurement.
