Produktbeschreibung
The JK6Y6 sits at the lighter end of Dell’s dual-battery configuration for the Inspiron 5000/7000 thin-and-light and Latitude 3000 business series — a 3-cell, 40Wh unit paired against the 4-cell, 53Wh H5CKD in the same chassis lineup. For procurement teams handling large IT refresh cycles or repair depot inventory, this distinction is non-negotiable: both batteries share compatible laptop models on paper, but the connector pinout and cable routing differ. Always verify the original P/N printed on the battery label inside the chassis before placing a bulk order.
Our manufacturing process targets Grade-A cell standards throughout: capacity-matched cell grouping within ±20mAh per cell, PCB trace impedance testing, and 100% capacity discharge verification before packaging. Outgoing QC rejection rates on standard lots consistently run below 0.3%.

Merkmale und Vorteile
✅ Precision Cross-Reference, Zero Guesswork Procurement
Every shipment includes a full P/N cross-reference sheet covering JK6Y6 / C5KG6 / CF5RH / 5NDNH / K3N6W. IT distributors and repair shops can confirm the correct unit without disassembly — reducing return rates and minimizing inventory risk on bulk stock.
✅ 3-Cell Compact Form Factor, Drop-In OEM Fit
Rated at 11.25V / 40Wh / 3,550mAh with overall dimensions matched to OEM spec (approx. 333mm × 100mm × 10.5mm). Installs directly into the original battery bay without modification — critical for refurbishment production lines and high-volume repair operations where installation time per unit matters.
✅ 4-Layer PCB Protection, Consistent Across Bulk Runs
Integrated protection covers overcharge (cutoff >12.6V), over-discharge (protection <8.25V), over-temperature (circuit break >70°C), and short-circuit self-recovery. High batch-to-batch consistency means your team doesn’t need to re-inspect incoming stock before deployment — a direct reduction in receiving labor cost.
✅ Factory Direct Pricing, Flexible Small-Batch Supply
No intermediary markup. Orders ship directly from our production facility with stable lead times and rolling replenishment support. Designed for IT asset management companies, laptop repair chains, and B2B e-commerce platforms that need continuous stock without the capital commitment of large one-time orders.
✅ OEM / White-Label Customization Available
Neutral packaging, branded label printing, or fully custom packaging are all negotiable. Suitable for resellers and refurbished laptop manufacturers that require differentiated presentation. Sample units with full electrical test reports are available before committing to a production run.

Häufig gestellte Fragen
Q1: What is the difference between JK6Y6 and H5CKD — which one do I need?
A: These two batteries cover the same laptop models but are not interchangeable. JK6Y6 is a 3-cell, 40Wh, 11.25V unit. H5CKD is a 4-cell, 53Wh, 15V unit. Connector position and cable length differ between the two. Open the laptop’s back cover, read the P/N printed directly on the original battery label, and order by P/N — do not rely on model number alone.
Q2: Which Dell laptop models are compatible with the JK6Y6 battery?
A: Compatible with: Dell Inspiron 5300, 5301, 5401, 5402, 5408, 5409, 5501, 5502, 5508, 5509; Inspiron 5400, 5406, 7405 2-in-1; Inspiron 7300, 7306, 7500, 7506 2-in-1 Silver Series; Latitude 3410, 3510; Vostro 5300, 5301, 5401, 5402, 5501, 5502. Important: does NOT fit Inspiron 7300/7306/7500/7506 2-in-1 Black Series — the connector is different.
Q3: The laptop won’t recognize the new JK6Y6 battery after installation — how do I fix it?
A: This is a common Dell firmware behavior, not a defective battery. Steps to resolve: (1) Power off completely and unplug the AC adapter. (2) Reseat the battery connector — confirm the latch is fully engaged. (3) Hold the power button for 20 seconds to drain residual charge. (4) Plug in AC power and boot. Run a battery diagnostic via Dell SupportAssist or check BIOS for battery status. Most cases resolve after this sequence.
Q4: What is the cycle life of the JK6Y6 battery?
A: Rated for 300–500 full charge-discharge cycles (0%–100%). Under normal use — approximately one full cycle per day — expected service life is 1.5 to 2.5 years. Chronic operation on AC power without periodic full discharge accelerates cell degradation. Running one or two full discharge-recharge cycles per quarter extends usable lifespan.
Q5: Does your factory support sample orders before bulk commitment?
A: Yes. Sample units ship with a full electrical test report covering actual discharge capacity, internal resistance, and cycle data. Bulk orders support rolling delivery schedules. Payment terms include T/T, L/C, and platform escrow. Standard sample lead time is 3–5 business days; bulk production lead time is 7–15 business days depending on order volume.
Q6: What quality inspections are performed before shipment? What certifications apply?
A: Every unit undergoes: actual discharge capacity verification (≥95% of rated capacity), internal resistance testing, dimensional and connector inspection, and thermal cycling stress test. Batch-level CE / FCC / RoHS documentation is available and can be provided with the order. If your procurement process requires additional certification, contact us in advance and we will coordinate with the appropriate testing body.
