Product Description
The AA-PBYN4AB replacement battery targets one of Samsung’s widest-distribution ultrabook platforms from the Series 5 Ultra and ATIV Book 5 era — a device family that shipped in high volumes through education, SMB, and consumer channels across North America, Europe, Asia-Pacific, and the Korean domestic market. At 7.4V and 45Wh, this unit matches the OEM specification across eight device series under the 530U and 535U naming conventions.
The Samsung Series 5 Ultra battery footprint covers NP530U3B, NP530U3C, NP532U3C, NP532U3X, NP535U3C, NP535U3X, NP540U3C, and NP542U3X device series — plus ATIV Book 5 configurations sharing the 530U3C chassis — with four cross-reference codes (AA-PLWN4AB, BA43-00336A, HT3691FC700364) resolving to the same physical stock position. Regional sub-model variants spanning US, UK, German, French, Italian, Chinese, and Southeast Asian market codes are covered under this single P/N.
For institutional buyers or depot accounts that absorbed Samsung ultrabook fleets during the 2012–2014 procurement cycles — a period when the Series 5 Ultra was a standard education and SMB laptop choice — this P/N provides continued battery supply for a device generation that remains in active service in many managed environments. One stock position covers the full device cohort without segmentation by regional sub-model.

Features & Advantages
✅ 🔋 Cell Vendor Precision: Why Li-Polymer Architecture Matters on the 530U Platform
The Samsung Series 5 Ultra was built around a Li-Polymer cell pack from the outset — a design choice that gives the 530U chassis its slim profile and determines the charge management parameters the EC expects. Li-Polymer cells deliver a flat discharge curve at 7.4V that the 530U embedded controller is tuned to read; a Li-ion replacement unit with nominal voltage variance introduces a charge-curve mismatch that the platform’s power management firmware interprets as premature capacity depletion, triggering a low-battery alert earlier than actual depletion. This unit uses Li-Polymer cells matching the OEM cell architecture, ensuring the EC’s state-of-charge estimation remains accurate across the full discharge range.
✅ 🔁 Eight Device Series and Four Cross-Reference Codes Under One Stock Position
AA-PBYN4AB covers NP530U3B, NP530U3C, NP532U3C, NP532U3X, NP535U3C, NP535U3X, NP540U3C, and NP542U3X series — along with ATIV Book 5 configurations on the 530U3C chassis. Cross-reference codes AA-PLWN4AB, BA43-00336A, and HT3691FC700364 all draw from the same stock line. Service accounts managing regional variant sub-models — including NP530U3C-A07IT, NP530U3C-A07SE, NP530U3C-A03AU, NP530U3C-A01DE, NP535U3C-A02IT — order the same unit regardless of suffix, simplifying purchase documentation across a multi-region device fleet.
✅ ⚡ Series 5 Ultra EC Charge Behavior and BMS Protection Sequence
On the 530U platform, a charge-inhibit condition after battery replacement most often presents as a status icon showing AC power connected but battery percentage frozen at the level registered before removal. The embedded controller on this chassis performs its battery state query at power-on and again on each AC connect event. Over-discharge protection in this unit’s BMS holds the cell voltage floor above the threshold that triggers an unrecoverable EC fault on the 530U firmware — preventing the non-charging state that persists across reboots. Overcharge cutoff engages at the cell boundary before any EC-level charge-suspend event, and short-circuit interrupt operates independently of the authentication handshake so protection is active from the moment the connector seats.
✅ 📦 Sample-to-Volume Escalation for Samsung Ultrabook Fleet Accounts
Depot and institutional accounts evaluating AA-PBYN4AB for a Series 5 Ultra or ATIV Book 5 fleet replacement program can request sample units prior to a volume commitment. The sample path runs on the same SKU as volume fulfillment — no separate qualification P/N, no re-certification step between sample and production stock. Once sample performance is confirmed against the device fleet, the volume order draws from the identical stock position. Wholesale pricing applies at the volume tier; low MOQ on initial orders allows gradual fleet rollout without a large upfront inventory commitment. ATIV Book 5 and Series 5 Ultra P/Ns can be combined on the same order.
✅ 🌐 Ordering Risk: Extended-Capacity Variants Listed Under the Same P/N Cross-References
A distinct procurement advantage for buyers sourcing AA-PBYN4AB from this channel: several aftermarket listings use AA-PBYN4AB, AA-PLWN4AB, and BA43-00336A cross-references to sell higher-voltage (7.6V) or higher-capacity (59Wh) units that fall outside the OEM spec for the 530U platform. These units may not seat correctly in all 530U chassis variants and introduce charge profile variance the 530U EC was not designed for. This stock position supplies the OEM-spec unit — 7.4V, 45Wh, Li-Polymer — with no extended-capacity substitution. For procurement officers specifying OEM-equivalent replacement units in service contracts, this distinction eliminates a common source of post-installation compatibility complaints on this platform.

FAQ
Q1: AA-PBYN4AB and AA-PLWN4AB both appear in cross-reference databases — are these separate P/Ns for different device configurations, or the same unit under two Samsung part designations?
A1: AA-PLWN4AB is a Samsung internal designation that was used in certain regional OEM documentation alongside AA-PBYN4AB — both reference the same physical battery unit at 7.4V and 45Wh. The connector, cell configuration, and BMS architecture are identical. No fitment distinction exists between devices listed under one designation versus the other; purchase orders may reference either P/N and will draw from the same stock position. AA-PBYN4AB is the more widely indexed primary identifier in aftermarket parts databases and should be used as the reference P/N for procurement records.
Q2: Some aftermarket listings for AA-PBYN4AB show 7.6V and 59Wh. Is that an upgraded option or a different product entirely?
A2: That is a different product — a higher-capacity aftermarket unit from certain sellers that uses the same cross-reference P/N strings to index their expanded-capacity battery against this platform. The OEM specification for the Samsung Series 5 Ultra is 7.4V and 45Wh. The 7.6V / 59Wh unit may not seat correctly in all 530U chassis variants and operates outside the voltage window the Series 5 Ultra’s charge management circuit is tuned for. This stock position supplies the OEM-spec unit at 7.4V and 45Wh — buyers should verify the voltage and Wh figures on any listing before purchasing to avoid the higher-capacity substitution.
Q3: Does coverage include the Samsung NP532U3C and NP532U3X, or only the 530U and 535U lines?
A3: NP532U3C and NP532U3X are both confirmed compatible with AA-PBYN4AB. The 532 sub-series shares the same battery bay, connector, and EC charge profile as the NP530U3C and NP535U3C. Depot accounts servicing Samsung ultrabook fleets that include 532-series devices alongside 530 and 535 units do not require a separate battery SKU — AA-PBYN4AB covers all three sub-series under one stock position.
Q4: After installing AA-PBYN4AB in a Series 5 Ultra, the battery percentage indicator appears frozen and does not update on charge or discharge. What is the cause?
A4: A frozen percentage reading on the Series 5 Ultra after battery replacement indicates the embedded controller has not completed a full calibration cycle with the new cell pack. The EC on this platform retains state-of-charge history from the previous battery and may not update the gauge until a complete discharge-to-charge cycle resets the calibration register. To resolve: allow the battery to discharge fully until the device powers off, then charge uninterrupted to 100% without using the device. After one complete cycle, the EC recalibrates the gauge against the new cell pack and percentage reporting normalizes. If the indicator remains frozen after two full cycles, a full EC reset — power off, AC disconnected, power button held for 20 seconds — will clear the retained state.
Q5: We need to order AA-PBYN4AB as part of a broader Samsung fleet battery replenishment covering multiple series. How does the ordering process work?
A5: Place the full multi-series order in one request — AA-PBYN4AB alongside any other Samsung battery P/Ns in your replenishment cycle. Submit the complete P/N list with quantity requirements and we’ll return consolidated pricing in a single quote. Low MOQ applies to the full order without per-P/N minimums. For repair depot accounts running recurring Samsung ultrabook service contracts, standing order terms can be arranged to simplify each replenishment event. Contact us with your parts list to begin.
Q6: The Samsung Series 5 Ultra 530U3C appears in purchasing records under both “NP530U3C” and “NP-530U3C” — does the hyphenated format indicate a different device or battery requirement?
A6: No difference in battery requirement. “NP-530U3C” with a hyphen and “NP530U3C” without are the same device — the hyphenated format appears in some Samsung official documentation and regional distributor records, while the unhyphenated version is the standard aftermarket database format. Both reference the same hardware, the same battery bay, and the same AA-PBYN4AB specification. Procurement systems that log both formats against the same physical device can consolidate both entries to a single battery SKU without any compatibility qualification step.
