Descripción del Producto
The HP HT03XL is the single highest-volume battery platform in HP’s consumer notebook line. It powers the complete run of Pavilion 14, 15, and 17 machines sold globally from 2018 to 2023 — a fleet now deep into the replacement-battery window. For repair centers, IT resellers, and wholesale distributors, that installed base translates directly into consistent, repeat demand.
Our factory has specialized in HP-platform battery packs for over a decade. Every HT03XL unit we ship is built on the same electrode stack geometry as the OEM reference design: 3-cell Li-ion polymer, 11.55V nominal, 41.9Wh rated. No capacity padding in the spec sheet, no refurbished cells in the assembly line.

Características y ventajas
✅ Grade-A Cell Consistency Across Every Batch
We source electrode cells from a fixed supplier pool — no spot-market substitutions between production runs. Each cell lot passes incoming capacity verification at ±2% tolerance before assembly. For distributors placing repeat orders, this matters: the battery you sample today will match the batch you receive in six months.
✅ BMS Chip Pre-Calibrated for HP Power Manager
The integrated Battery Management System is flashed with HP-platform firmware before shipping. When installed, the laptop immediately reads correct capacity percentage and charge cycles — no “plugged in, not charging” issues, no BIOS update required. Repair technicians can hand the repaired unit back to the end user without a secondary software step.
✅ Voltage Tolerance Built Into the Design
HP service documentation specifies 11.4V–11.55V as the valid range for this platform. Our cells discharge with a curve that stays within that window from 100% to 5% SOC. The practical result: no screen flicker under GPU load, no touchpad dropout when the battery dips below 20%.
✅ Wholesale Supply Chain Built for B2B Buyers
We maintain a minimum 10,000-unit rolling stock of HT03XL — enough buffer to fulfill urgent repair center top-ups without lead time surprises. Bulk orders come with a full packing list, item-level QR traceability, and documentation support for your import compliance team. Custom OEM labeling is available on qualifying volumes.
✅ Proven Shelf Life for Inventory Holders
Batteries are shipped at 40–60% SOC with nitrogen-sealed inner packaging, meeting IEC 62133 storage guidelines. Under ambient warehouse conditions (15–25°C), self-discharge loss stays below 3% per month. Distributors carrying 90-day inventory cycles will receive units still within spec at the point of sale.

Preguntas frecuentes
Q1: Is the HT03XL battery the same as the HW03XL?
No. They look nearly identical but are not interchangeable. HT03XL is 11.55V / 41.9Wh and fits the Pavilion 14/15/17 CE/CF/CS/DA/DB/DW series. HW03XL is a different platform with a different connector pinout. Installing the wrong one will not damage the laptop, but it simply won’t make electrical contact. Always verify the part number printed on your original battery before ordering.
Q2: Why do some HT03XL listings say 41Wh and others say 41.9Wh or 41.7Wh?
This is a factory rounding difference, not a meaningful spec gap. HP’s own service manuals list both 41Wh and 41.9Wh for L11119-855 depending on the chassis generation. Any unit in the 41–42Wh range is within normal production tolerance for this platform. For wholesale buyers: when auditing incoming stock, use voltage (11.4–11.55V) and cell count (3-cell) as your primary verification points — the Wh figure alone is not a reliable rejection criterion.
Q3: Will my HP laptop show “plugged in, not charging” after I install a new HT03XL?
Only if the BMS chip is not pre-calibrated for HP’s power management protocol. Our units ship with firmware that HP Power Manager recognizes on first boot. If a “plugged in, not charging” message does appear, the fix is straightforward: disconnect the AC adapter, power down, hold the power button for 15 seconds to fully discharge residual voltage, then reconnect the charger. This resets the HP EC controller and resolves 95% of such cases without any BIOS update.
Q4: What is your minimum order quantity and standard lead time for bulk HT03XL orders?
We maintain rolling stock specifically on the HT03XL platform. Small batch orders are fulfilled from in-house inventory with a 3–5 business day dispatch. For larger volume orders requiring custom labeling or special packing configurations, production lead time is 7–14 business days from order confirmation. Contact our sales team for a tiered pricing sheet based on your projected monthly volume.
Q5: Do you provide sample units before committing to a bulk order?
Yes. Sample units are available for qualified buyers — typically repair shop owners, distributors, or IT procurement teams. Samples include the same cell lot and BMS firmware as production runs, so performance testing on a sample is a valid proxy for batch quality. Reach out via the contact form with your business details and intended use volume.
Q6: How should we store HT03XL batteries in a warehouse environment?
Store at 40–60% SOC in a dry environment between 15–25°C. At these conditions, self-discharge is below 3% per month — so a 90-day warehouse cycle loses less than 10% charge, well within HP’s acceptance threshold for new-install batteries. Avoid stacking more than 5 units vertically without packaging support. Do not store near heat sources or in direct sunlight. For inventory older than 6 months, we recommend a capacity spot-check with a lab charger before distribution.
