Descripción del Producto
The J1KND is one of the most widely deployed 6-cell battery platforms Dell ever shipped — spanning the entire Inspiron R-series (13R through 17R) and the Vostro 3000 business line from roughly 2010 to 2013. That install base is still substantial in the IT refurbishment and repair depot market: enterprise lease returns, school district refreshes, and small business PC pools all generate steady J1KND replacement demand. For procurement teams, the key sourcing issue with this battery is not compatibility — the P/N list is well-documented — but rather cell quality variance across suppliers. Many aftermarket units in circulation ship with B-grade or recycled cells that pass initial bench tests but drop below 70% capacity within 150 cycles. Our production process uses capacity-matched Grade-A cells throughout, with outgoing QC rejection below 0.3% on standard lots.
One specification point worth flagging for buyers: the J1KND ships in two capacity variants in the market — the standard 48Wh / 5,200mAh version and a higher-density 58Wh version. Both share the same P/N and connector. Confirm the required capacity with your end customer or end chassis spec before placing a bulk order.

Características y ventajas
✅ Deepest P/N Cross-Reference in This Category
With 23+ verified original Dell part numbers mapping to J1KND, this battery covers more Inspiron and Vostro configurations per SKU than any other single 11.1V Dell unit. For repair depots running multi-model inventory, stocking J1KND reduces SKU count without sacrificing fitment accuracy.
✅ 6-Cell Architecture, Full-Day Runtime for End Users
At 48Wh / 5,200mAh across 6 cells, this battery restores genuine all-day runtime to aging Inspiron R-series hardware — a critical selling point for refurbishers reselling corporate lease returns into the SMB market. Runtime improvement over a degraded OEM battery is typically 3–4 hours under mixed-use conditions.
✅ Grade-A Cells, 500+ Cycle Rated Lifespan
Rated for 500+ full charge-discharge cycles using capacity-matched Grade-A Li-ion cells. Cell grouping tolerance held within ±20mAh per unit. This directly affects return rates for repair shops: consistent cell quality means fewer warranty claims from end customers 6–12 months after installation.
✅ Factory Direct — No Distributor Markup on Bulk Orders
Orders ship directly from production. Pricing reflects manufacturer cost structure, not reseller margins. Rolling replenishment orders are supported, which suits IT asset management companies and laptop repair chains that need continuous stock without large one-time capital outlays.
✅ OEM / Private Label Packaging Available
Neutral white-box, custom branded label, or retail blister pack — all negotiable. Refurbished laptop OEMs and B2B resellers can request differentiated packaging to match their brand presentation. Sample units with full electrical test data ship before production commitment.

Preguntas frecuentes
Q1: What is the difference between the J1KND 48Wh and 58Wh versions — are they interchangeable?
A: Both versions share the P/N “J1KND” and the same physical connector, so they fit the same chassis without modification. The 58Wh variant packs higher-density cells for longer runtime. They are electrically interchangeable — the laptop’s charge controller handles either version without issue. Confirm which capacity your end customer needs by checking the Wh rating on the original battery label inside the chassis.
Q2: Which Dell laptop models use the J1KND battery?
A: The J1KND covers: Inspiron 13R (N3010, N3110), 14R (N4010, N4040, N4050, N4110, M4040), 15R (N5010, N5020, N5030, N5040, N5050, N5110, M5010, M5030, M5040, M5110), 17R (N7010, N7011, N7110), Inspiron 3420 and 3520, plus Vostro 1440, 1450, 1540, 1550, 2420, 2520, 3450, 3550, 3555, and 3750. Always cross-check both the laptop model and the P/N on the original battery label before ordering.
Q3: The Dell laptop charges to 100% but the battery drains within 1–2 hours — is the replacement battery defective?
A: Not necessarily. Two likely causes: (1) Dell’s battery meter is calibrated against the original OEM battery profile, so an uncalibrated replacement may show inaccurate runtime estimates even if capacity is correct. Run a full discharge-to-shutdown cycle, then charge to 100% uninterrupted — this recalibrates the meter. (2) If runtime remains short after calibration, check actual capacity using HWiNFO64 or BatteryCare. If measured capacity is below 90% of rated spec, the unit qualifies for warranty replacement.
Q4: Does the J1KND battery need to be activated or charged before first use?
A: Ship charge on replacement Li-ion batteries is typically 30–60%. There is no chemical “activation” required with modern Li-ion cells — that concept applies to older NiMH/NiCd chemistry. For best long-term performance, do one full charge cycle (0% to 100%) before regular use. Avoid leaving at 0% for extended storage periods as deep discharge accelerates cell degradation.
Q5: What are the MOQ and lead time for bulk J1KND battery orders?
A: We support small batch orders with no steep minimum quantity requirement — suitable for repair shops and distributors testing new SKUs. Standard bulk production lead time is 7–15 business days depending on order volume. Sample units (with full electrical test reports covering discharge capacity, internal resistance, and cycle data) ship within 3–5 business days. Accepted payment terms: T/T, L/C, and platform escrow.
Q6: How do you ensure consistency across a bulk shipment of J1KND batteries?
A: Every unit in a production batch undergoes: actual discharge capacity verification (≥95% of rated 48Wh), internal resistance measurement, dimensional and connector fit check, and high/low temperature static test. Cell groups are capacity-matched within ±20mAh at the assembly stage. Batch QC documentation — including test pass rates and electrical summary — is available upon request for procurement audits.
