HP HS04 Replacement Laptop Battery | 14.8V 41Wh 4-Cell for 240 G4 G5, 250 G4 G5, Pavilion 14 15 Series

Q1: Can I use an HS04 to replace my original HS03 battery?
Yes, and this is one of the most common substitutions in the HP G4/G5 repair market. The HS03 and HS04 share the same physical form factor, same 4-pin connector, and same battery bay dimensions. The key difference is cell count: HS03 is 3-cell (10.8V–11.1V, ~31Wh), while HS04 is 4-cell (14.8V, 41Wh). Substituting an HS04 into an HS03 slot is a capacity upgrade — your laptop will run longer per charge. The HP BMS firmware on all G4/G5 chassis recognizes both variants without configuration changes. In a wholesale context, stocking only HS04 covers both replacement scenarios.

Q2: Why does the HS04 have multiple voltage ratings — 14.4V, 14.6V, and 14.8V — across different sellers?
All three figures refer to the same physical battery platform. 14.8V is the nominal cell voltage for a 4-cell Li-ion pack at approximately 50% state of charge. 14.4V is the HP OEM label specification, reflecting a conservative rating at partial discharge. 14.6V appears in some third-party listings as an average between the two. For procurement teams: any HS04-format pack rated between 14.4V and 14.8V is within the normal operating tolerance of the HP G4/G5 power circuit. The connector pinout is the definitive compatibility check — not the voltage label.

Q3: How do I verify an HS04 battery is genuine Grade-A and not refurbished or B-grade cells?
Three practical checks: First, request a cell lot traceability report from your supplier before the purchase order — legitimate manufacturers can provide this. Second, test incoming stock with a lab charger (iCharger or similar) set to 0.5C discharge; a genuine 41Wh pack should return 39–43Wh at room temperature. Third, check the self-discharge rate after 30 days of storage at 40% SOC — B-grade or refurbished cells typically lose 8–15% per month versus under 3% for Grade-A. If your supplier cannot provide cell lot documentation, that is a meaningful red flag regardless of the stated capacity on the spec sheet.

Q4: What is the realistic shelf life for HS04 inventory held in a standard warehouse?
The 18650 cylindrical cell format used in the HS04 has lower self-discharge than Li-polymer pouches, which is a practical advantage for distributors carrying buffer stock. At 40–60% SOC and 15–25°C storage temperature, self-discharge is under 2.5% per month — a 6-month warehouse cycle loses approximately 12–15% charge, still within HP’s acceptable new-install range. For inventory older than 9 months, we recommend a capacity refresh cycle before distribution to end users or corporate IT teams.

Q5: Do you support OEM private labeling or custom packaging for the HS04?
Yes, on qualifying volume orders. Options include custom label printing on the battery housing, retail-ready individual box packaging with your branding, and master carton labeling matching your warehouse or 3PL inbound requirements. Lead time for custom packaging runs adds 5–7 business days to the standard dispatch window. Provide your artwork files and packaging specification sheet to our sales team for a quote.

Q6: What is your quality rejection rate, and how do you handle DOA or warranty claims on bulk HS04 orders?
Our outgoing QC pass rate on the HS04 platform is above 99.2% on a rolling 12-month basis, based on full-voltage and capacity spot checks on every batch. For bulk orders, we provide a Certificate of Conformance per shipment. DOA units are handled with a replacement shipment dispatched within 5 business days of claim confirmation — we do not require return shipment of individual units below a defined batch threshold. Warranty period is 12 months from shipment date, covering manufacturing defects and capacity degradation below 70% of rated Wh.
