وصف المنتج
The RJ40G is the high-capacity 4-cell battery option for Dell’s Latitude 5420/5520 and Precision 3560 platform — running at 15.2V and 63Wh. It shares the same chassis with the WY9DX (11.4V / 42Wh, 3-cell), but the two are not interchangeable: voltage, cell count, connector pinout, and PCB charging protocol all differ. Before ordering, open the back panel and confirm the P/N printed directly on the installed battery. Do not rely on the laptop model alone.

الميزات والمزايا
✅ Grade A Cells — Full 63Wh Rated Capacity, No Underspec
Built with Grade A Li-ion cells that deliver the full rated 3941mAh from the first cycle. Some aftermarket alternatives ship at 80–85% of stated capacity due to lower-grade cells. This unit is factory-tested at 100% capacity before dispatch.
✅ 15.2V Architecture — Correct Voltage, No Charging Errors
The RJ40G runs at 15.2V nominal — a 4S cell configuration distinct from the 3S/11.4V WY9DX. Attempting to run a 3-cell battery in a 4-cell slot (or vice versa) triggers Dell’s BIOS protection and generates charging errors. This unit matches the original electrical specification precisely.
✅ Multi-Layer PCB Protection — Safe for High-Volume Repair Operations
Integrated protection circuit handles overcharge, over-discharge, short circuit, and thermal events. Gold-plated SMBus contacts maintain reliable communication with the Dell BIOS — no “battery not recognized” alerts on standard firmware configurations.
✅ CE / FCC / RoHS Certified — Compliant for All Major Import Markets
CE covers EU and UK distribution. FCC covers North American importers. RoHS satisfies corporate procurement compliance requirements in most enterprise purchasing frameworks. Full test documentation and UN38.3 transport reports are available on request for customs clearance.
✅ Drop-In Replacement — No Configuration Required
Electrically and physically compatible with original Dell BIOS charging profiles. The SMBus chip reports accurate state-of-charge data to Windows/Linux battery management — no driver installation, no firmware update, no calibration tool needed post-installation.
✅ Factory Direct Stock — Fast Dispatch, Bulk Pricing Available
Inventory is held at the production facility. Trial orders are accepted for quality verification before scaling. Tiered bulk pricing applies from the first confirmed PO. Lead time for in-stock SKUs: 3–5 business days to major ports worldwide.

التعليمات
Q1: What is the difference between the Dell RJ40G and WY9DX batteries for the Latitude 5420/5520?
A1: Both batteries fit the same laptop models, but they are completely different parts. The RJ40G runs at 15.2V with 63Wh capacity (4-cell, 4S configuration). The WY9DX runs at 11.4V with 42Wh (3-cell, 3S configuration). Voltage, cell count, PCB pinout, and charging protocol all differ — they cannot be swapped. Open the back cover of the laptop and read the P/N printed on the installed battery before placing an order.
Q2: Will the RJ40G battery work with the Dell Precision 3560?
A2: Yes. The Dell Precision 15-3560 is a verified compatible model for the RJ40G. Confirmed sub-model platform codes include P104F, P104F001, P104F002, and specific unit codes 3H45Y, 4MTF7, 758J7, 7RV10, and F3T9T. The same note applies: the Precision 3560 also shipped with either RJ40G or WY9DX depending on factory configuration, so confirm the original battery P/N before ordering.
Q3: Does the RJ40G need any calibration or BIOS update after installation?
A3: No BIOS update is required. The RJ40G’s SMBus chip communicates battery state-of-charge data directly to Dell’s firmware on first boot. For initial cycle performance, discharge to around 15–20% on first use, then charge to full without interruption, and repeat 2–3 times. This stabilizes the reported capacity figure in Windows battery diagnostics.
Q4: What certifications does this battery carry, and can I get documentation for import compliance?
A4: CE, FCC, and RoHS certifications are standard. For B2B buyers requiring customs clearance or corporate procurement audits, we can provide full documentation: test reports, MSDS/SDS, and UN38.3 lithium battery transport testing reports. Request documentation before placing your first bulk order.
Q5: What is the minimum order quantity (MOQ) and what is the lead time?
A5: Small trial orders are accepted for new B2B customers — no fixed minimum is required for initial qualification. Tiered pricing applies on confirmed purchase orders. For in-stock inventory, lead time is 3–5 business days to major international ports. Contact us with your target quantity and destination for a formal quote.
Q6: What warranty and after-sales support applies to bulk orders?
A6: Each unit carries a 12-month warranty against manufacturing defects under normal operating conditions. For B2B accounts, we support pre-shipment batch QC inspection, third-party inspection (e.g., SGS) on request, and DOA replacement within the warranty window. Sample units for pre-order testing can be arranged before committing to full production volumes.
