Descrição do produto
The C21N1347 is the battery platform for ASUS’s mid-2010s consumer notebook lineup — the X555, A555, F555, K555, and their many regional naming variants. These machines sold across global markets from 2014 through 2017 at price points that made them the default “first laptop” purchase for students and budget-conscious buyers. The volume was enormous, and the installed base is now 8–10 years old. That is deep into the replacement battery window.
What makes the C21N1347 commercially distinctive is its coverage breadth. ASUS used the same battery platform across more than ten series designations — X555, A555, F555, K555, R556, VM510, VM590, W519, Y583, FL5500, FL5600, and regional variants of each. A repair shop stocking a single C21N1347 SKU handles a wider range of incoming ASUS work orders than almost any other single aftermarket battery in the catalog.
C21N1347 vs C21N1509 — The Confusion That Drives Returns
These two batteries are frequently confused in search results and some listing aggregators incorrectly treat them as interchangeable. They are not:
-
C21N1347 — 7.5V, 37Wh, 2ICP4/63/134, spare 0B200-01200100 — X555/A555/F555/K555/R556 platform
-
C21N1509 — 7.6V, 38Wh, C21PQ9H, spare 0B200-01750000 — A556/X556/K556/F556 platform
The voltage difference is small but the connectors differ. A C21N1509 will not seat in a C21N1347 chassis. The definitive check is the original battery label — the spare part number or cell code resolves the question immediately. Repair shops that train customers to photograph the original battery label before inquiring eliminate this return cause entirely.
The Removable Bay Advantage on X555 Platform
Unlike ASUS’s slim ultrabook batteries, the X555 series uses an external slide-latch battery bay. No bottom panel removal, no prying, no ribbon cable risk. Experienced technicians swap this battery in under 90 seconds. For repair shops processing high volumes of budget ASUS notebooks — a common workflow in secondary market repair chains and refurbishment programs — the zero-disassembly format is a meaningful throughput advantage.

Características e vantagens
✅ 📦 Widest Coverage Per SKU in Our ASUS Consumer Catalog
The C21N1347 covers more distinct ASUS model numbers than any other single battery platform in this catalog. For repair shops managing a broad ASUS customer base — particularly shops in markets where the X555 and A555 series were the dominant entry-level notebooks — a single C21N1347 stock position resolves the majority of ASUS battery work orders without needing to source multiple SKUs. The economic implication is straightforward: lower inventory investment, fewer stockout events, simpler reorder management.
✅ 🔄 External Removable Bay — Zero-Disassembly on X555 Platform
The X555 series uses a slide-latch external battery bay. No bottom panel removal, no tools required. This is the same form factor as the HP HS04 and LA04 platforms — a design that repair technicians can process in under 90 seconds per unit. For refurbishment programs or secondary market operations processing batches of budget ASUS notebooks, the zero-disassembly swap significantly increases throughput compared to internal battery platforms requiring full bottom panel access.
✅ ⚠️ C21N1347 vs C21N1509 — Know the Boundary Before Ordering
The C21N1347 (X555 platform) and C21N1509 (X556/A556 platform) appear frequently in adjacent search results and are sometimes incorrectly listed as substitutes. Voltage is similar — 7.5V vs 7.6V — but the connectors differ and the packs are not interchangeable. The boundary is the chassis generation: X555 series uses C21N1347, X556/A556/K556 series uses C21N1509. Spare part number on the original battery label is the definitive check. For wholesale buyers managing both platforms, we can supply both SKUs in a single consolidated purchase order.
✅ 🌍 Global Market Coverage — Depth in Secondary Markets
The X555, A555, and F555 series sold across North America, Latin America, Southeast Asia, the Middle East, and Eastern Europe — markets with 7–10 year hardware refresh cycles. Repair demand on this platform is not declining; it is running at a steady baseline across multiple global regions simultaneously. For distributors with coverage in these markets, the C21N1347 is a catalog staple rather than a specialty item. The replacement window on a 2014–2017 installed base at this price tier will remain open for several more years.
✅ 🏭 Consistent Cell Supply for High-Volume Repair Chains
The C21N1347’s breadth of machine coverage makes it a high-turnover SKU for repair shops serving general consumer laptop markets. We maintain standing inventory and run this platform on a continuous production basis with a fixed cell supplier specification. For repair chains placing weekly replenishment orders, same-batch consistency matters — a customer who praised the previous batch’s performance should get the same result from the next one. Our cell lot documentation on each CoC gives you the traceability to verify this across orders.

Perguntas frequentes
Q1: What is the difference between C21N1347 and C21N1509 — can they be used interchangeably?
No. C21N1347 (7.5V, 37Wh, spare 0B200-01200100) covers the X555/A555/F555/K555 platform. C21N1509 (7.6V, 38Wh, spare 0B200-01750000) covers the X556/A556/K556/F556 platform. The voltage difference is small but the connector housings differ between the two generations — a C21N1509 will not seat correctly in a C21N1347 chassis. The definitive identification method: read the spare part number or cell code on the original battery label. 0B200-01200100 and 2ICP4/63/134 = C21N1347 platform. C21PQ9H = C21N1509 platform. Do not substitute based on similar voltage alone.
Q2: Does C21N1347 fit the X555 with both AMD and Intel processors?
Yes. ASUS released the X555 series with Intel Core i-series (X555LA, X555LN, X555LF), Intel Celeron/Pentium (X555LP), and AMD A-series (X555DA, X555DG, X555YI) processor configurations. All variants use the same C21N1347 battery specification. The battery bay, connector, and BMS protocol are consistent across all X555 processor variants. A single C21N1347 stock position covers the complete X555 lineup regardless of the CPU inside.
Q3: Some C21N1347 listings show 38Wh or 5,000mAh — is the correct spec 37Wh or 38Wh?
37Wh / 4,829mAh at 7.5V is the ASUS official specification for C21N1347. Listings showing 38Wh typically reflect either a 7.6V cell variant (which calculates to slightly higher Wh from the same cell capacity) or mild capacity rounding. Listings claiming 5,000mAh are either rounding or slight inflation. For incoming QC: a lab discharge at 0.5C should return 35–39Wh at room temperature on a genuine unit. Consistent readings below 33Wh indicate underspecced cells. The 7.5V vs 7.6V voltage labeling difference on this platform is within acceptable operating tolerance — the BMS and charging circuit handle both without issue.
Q4: The X555 series is 8–10 years old. Is repair demand still consistent enough to justify stocking C21N1347?
Yes, particularly for repair shops serving markets outside North America and Western Europe. The X555 and A555 series were among the top-selling budget notebooks in Latin America, Southeast Asia, the Middle East, and Eastern Europe between 2014 and 2017 — markets where hardware refresh cycles run 7–10 years. Secondary market resellers and refurbishment programs also maintain active C21N1347 demand as these machines are reconditioned for budget resale. For distributors covering these regions, C21N1347 is a staple catalog item. Demand will remain consistent for several more years given the scale of the installed base.
Q5: Can I order C21N1347 and C21N1509 together in a single purchase order to cover both X555 and X556 platforms?
Yes. We supply both platforms and support mixed-SKU purchase orders covering multiple ASUS battery models in a single shipment. Each model is packed in clearly separated, labeled inner cartons within the master shipment, with a consolidated Certificate of Conformance identifying both SKUs. For repair shops or distributors managing broad ASUS coverage across consumer notebook generations, consolidating C21N1347 and C21N1509 into one order reduces freight cost and simplifies the procurement documentation trail.
Q6: What documentation and warranty terms apply to bulk C21N1347 orders?
Each bulk shipment includes a Certificate of Conformance with cell lot number, production date, capacity QC results, and voltage verification parameters. Warranty is 12 months from shipment date covering manufacturing defects and capacity degradation below 70% of rated 37Wh. DOA claims require a photo of the defective battery label and brief failure description — return shipment is not required below our defined batch replacement threshold. Replacements dispatch within 5 business days of claim confirmation. For repair chains processing high weekly volumes, monthly batch-level QC summary reports are available on request.
