HP SA04XL Replacement Laptop Battery | 15.12V 55.67Wh 4-Cell for Envy X360 15-DR 15-DS 17-CG Series

Q1: Is the SA04XL interchangeable with the LK03XL or BN03XL?
No — and this is the most common ordering mistake on the HP Envy X360 line. The SA04XL runs at 15.12V (4-cell series architecture). The LK03XL runs at 11.55V (3-cell). The BN03XL is an entirely different platform for the Envy 13/14. None of these share a connector pinout with the SA04XL. Installing a 3-cell pack into a 4-cell chassis will not charge — the BMS voltage mismatch will cause the system to report no battery detected. The verification step before any bulk order: check the voltage printed on the original battery label. 15.12V = SA04XL platform. 11.55V = LK03XL platform.

Q2: Why does my HP Envy X360 shut down unexpectedly at 15–25% battery, even with a new SA04XL installed?
This is almost always a cell balancing issue, not a defective battery. In a 4-cell series pack, if one cell develops higher internal resistance than the others — either from a factory defect or from being stored at very low SoC — the BMS will cut off the pack when that weakest cell hits its minimum voltage threshold, even if the other three cells still have capacity remaining. The shutdown-at-20% symptom is the field indicator. On a properly assembled SA04XL with matched cells (±1% tolerance), this failure mode does not appear within the first 500 cycles. If a customer reports this symptom on a new replacement battery, the root cause is cell matching quality in the pack — request a replacement unit and ask your supplier for evidence of incoming cell QC parameters.

Q3: Do I need to run activation cycles on a new SA04XL before giving it to a customer?
No. The multi-cycle activation ritual is a carryover from NiMH chemistry and has no technical basis for Li-ion polymer cells. Our SA04XL units ship at 40–60% SoC with the BMS pre-initialized. Install the battery, charge to 100% once, and it will operate at full rated capacity immediately. Running forced deep-discharge cycles on a new Li-ion pack — particularly below 5% SoC — stresses the cells unnecessarily. For repair shops turning around high volume, eliminating the activation wait time is a direct throughput improvement.

Q4: What is the voltage difference between SA04XL and SA04055XL — are they the same battery?
Yes, they are the same battery. SA04055XL is simply a more explicit model designation where “055” refers to the 55Wh capacity tier. SA04XL is the generic designation used on HP’s spare parts system. Both refer to the 15.12V / 55.67Wh / 4-cell platform. The part number L43267-005 is HP’s internal spare number for this assembly. SAO4XL (letter O instead of zero) is a common misprint that appears on some listings — it refers to the same unit. For wholesale procurement documentation, use L43267-005 as the canonical reference number, as this is the HP-issued spare number that import/export paperwork will match to.

Q5: What batch sizes and lead times do you support for SA04XL wholesale orders?
We maintain standing stock on the SA04XL as part of our HP Envy premium platform inventory. Small batch orders fulfill from finished-goods stock with 3–5 business day dispatch. Volume orders requiring custom labeling, retail box packaging, or non-standard carton configurations carry a 7–10 business day lead time from order confirmation. For accounts with predictable monthly volume, we offer a forward-inventory reservation program — contact our sales team with your 90-day forecast for a dedicated stock allocation and tiered pricing structure.

Q6: How do you handle returns or warranty claims on SA04XL bulk orders?
Warranty is 12 months from shipment date, covering manufacturing defects and capacity degradation below 70% of rated 55.67Wh. Each bulk shipment includes a Certificate of Conformance with cell lot number, production date, and QC parameters. For DOA or early-failure claims: we require a photo of the battery label and a brief description of the failure symptom. Return shipment of individual units is not required below a defined batch threshold — we dispatch replacements within 5 business days of claim confirmation. For accounts tracking failure rates across multiple orders, we provide batch-level failure rate reports on a quarterly basis upon request.
