Descrição do produto
The AA-PLXN4AR replacement battery spans the full Samsung Series 9 900X3 ultrabook lineup — a 13.3-inch platform deployed heavily in corporate and education environments from 2012 through 2016. Procurement teams sourcing for these fleets encounter the same three part numbers interchangeably: AA-PLXN4AR, AA-PBXN4AR, and BA43-00349A. Stocking under this single SKU resolves all three without split purchase orders.
The 900X3 family runs across six hardware generations — 900X3B through 900X3G — with the NP-prefix variants covering regional market releases in the same chassis. Compatibility spans the entire generation set: NP900X3C and NP900X3D represent the highest-volume sub-series in the field, while 900X3E, 900X3F, and 900X3G hardware remains active in enterprise fleets where refresh cycles were extended.
IT asset managers working through a phased fleet refresh do not need a separate battery SKU for each 900X3 generation. One stock line clears the backlog across all variants — from a 900X3C unit purchased in 2012 to a 900X3G issued in 2015 — without per-generation qualification work.

Características e vantagens
✅ 🔬 Flat-Pack Li-ion Architecture Matched to the 900X3 Chassis Constraint
The 900X3 series was built around a 5.4mm-thick battery cavity — a dimension that eliminates any tolerance for mold deviation. What procurement decisions often miss is the consequence at the per-unit level: a battery that’s 0.3mm out of spec will either fail to seat or stress the chassis contacts over time, generating returns. Our cells are sourced to the flat-pack form factor spec, and the pack dimensions — 267.90 × 96.30 × 5.40mm — are produced from direct teardown tooling, not approximated drawings. For a repair depot placing a standing replenishment order, this means zero dimensional callbacks across batch.
✅ 📋 One P/N Covers Three Samsung Part Numbers in the Field
Samsung issued AA-PLXN4AR, AA-PBXN4AR, and BA43-00349A across production runs and regional documentation revisions — all three reference the same physical battery. Field technicians may pull any of these codes from a device label; sourcing under a single warehouse SKU resolves all three without maintaining parallel stock lines. The 900X3 series also extended through 900X3K sub-variants in some markets, with the same battery physically compatible. A stocking distributor carrying this P/N covers the complete 900X3 generation footprint in one position, confirmed across Samsung Series 9 900X3B through 900X3G hardware.
✅ ⚙️ EC Warning Suppressed at First Boot — No Recalibration Loop
Samsung’s embedded controller on the 900X3 platform initiates a charge authentication handshake within the first 30 seconds of a new battery installation. If the SMBus response from the BMS doesn’t match expected Samsung parameters — specifically the charge termination voltage and capacity register — the EC flags a “Battery needs to be replaced” warning immediately on a new unit, before any discharge has occurred. Our BMS firmware is programmed to the 900X3 SMBus specification: short-circuit interrupt is the first protection layer, overcharge cutoff is the second, and thermal monitoring closes the sequence. The EC reads the battery as within-spec on first handshake, and the state-of-charge meter reports accurately from the first cycle.
✅ 📦 Single-SKU Ordering Across a Multi-Generation Fleet
A service depot carrying the 900X3 series across multiple client accounts — some running 900X3C, others running 900X3E or 900X3G — doesn’t need separate line items per generation. One wholesale order covers all variants. Wholesale pricing is available for volume orders, and the 900X3 Samsung Series 9 compatibility footprint means fewer SKUs to track against open service tickets. Mixed-SKU orders accepted alongside other Samsung lines on the same purchase order.
✅ 🚚 Li-ion Flat-Pack Documentation Ready for Air Freight
Flat-pack Li-ion cells at 44Wh fall below the 100Wh IATA threshold for Section II handling, but freight forwarders working lithium battery shipments still require UN38.3 test reports and MSDS on file before confirming dangerous goods classification. Both documents are available on request for this SKU. Buyers coordinating multi-country distribution — particularly into the EU, AU, or Japan, where customs documentation requirements for Li-ion are enforced at the carrier level — can request the documentation package prior to committing to a volume order.

Perguntas frequentes
Q1: AA-PLXN4AR and AA-PBXN4AR appear on different devices I’m servicing — do I need to stock both separately?
A1: No. AA-PLXN4AR and AA-PBXN4AR are the same physical battery. Samsung assigned both codes across different production batches — the “PL” versus “PB” prefix reflects the internal cell chemistry designation used during different manufacturing periods, not a dimensional or electrical difference. BA43-00349A is a third code for the same unit, appearing in Samsung’s service parts documentation. A single stock position covers all three codes. When receiving a service order, any of the three on the device label routes to this SKU.
Q2: Some listings show 7.4V and others show 7.5V — which is correct for the 900X3 series?
A2: Both are correct for their respective contexts. 7.4V is Samsung’s OEM nominal voltage — the figure printed on the original battery label. 7.5V is the replacement market’s rated voltage, reflecting a slight cell chemistry variance that the 900X3 charger circuit accommodates without issue. The 0.1V difference falls within the tolerance band Samsung’s power management IC accepts. Either voltage spec replacement will charge and discharge normally. When cross-referencing against a device label showing 7.4V, this 7.5V replacement is the correct sourcing match.
Q3: Does this battery fit the 900X3K variants — specifically K01 and K02 — or only the 900X3C through 900X3G range?
A3: The 900X3K uses the same battery cavity and connector layout as the 900X3G. Battery codes AA-PLXN4AR, AA-PBXN4AR, and BA43-00349A appear in 900X3K service documentation. 900X3K-K01 and 900X3K-K02 are confirmed compatible. Buyers managing mixed Samsung Series 9 fleets that include 900X3K units can consolidate under this SKU without a separate line item for the K-suffix hardware.
Q4: After installing this battery, the 900X3 shows a “Battery needs to be replaced” warning even at full charge — what causes this?
A4: This warning on the 900X3 platform is triggered by the embedded controller when the battery’s SMBus response doesn’t match Samsung’s expected parameters — most commonly the capacity register value or the charge termination voltage. It does not indicate a faulty battery; it indicates a BMS firmware mismatch between the replacement and the Samsung EC’s expected handshake. Our BMS is programmed to the 900X3 spec. If this warning appears after installation, perform a full discharge and recharge cycle first — the EC recalibrates the state-of-charge reading after one full cycle. If the warning persists, the issue is likely a connector seating problem, not the BMS.
Q5: We’re a repair depot managing multiple Samsung Series 9 client accounts — can we place one order covering different Samsung battery lines alongside AA-PLXN4AR?
A5: Ordering direct from the manufacturer, mixed-SKU orders across Samsung battery lines are supported on the same purchase order. A depot running 900X3 alongside other Samsung platform batteries doesn’t need to split into separate orders per SKU. Submit the part numbers and quantities required, and we’ll confirm stock availability and lead time in one response. For accounts with recurring Samsung volume, standing replenishment arrangements can be discussed on the same contact.
Q6: What’s the correct way to identify which 900X3 generation a device is, when the external label is missing or worn?
A6: The most reliable method is Samsung’s BIOS system information screen — boot to F2 at startup and the model string (e.g., NP900X3C-A02DE) is reported in the first screen. If BIOS access is unavailable, the Windows device information page (Settings → System → About) reports the full model number Samsung registered at manufacture. As a secondary check, the chassis revision can often be identified from the bottom case part number, which follows a Samsung-documented format. All 900X3B through 900X3K variants use this battery regardless of generation — if the model string begins with 900X3 or NP900X3, this is the correct part.
