Replacement battery for HP 15 and 17 models

This 14.8 V lithium-ion pack replaces the original HS03 and HS04 cells in a wide range of HP 15‑BA, 15‑AY, 15‑AF, 14‑AM, 14‑AC, 14‑AF and 17‑X0 laptops. It matches the 33 Wh capacity and 2200 mAh rating of the factory units and fits the same physical footprint. The four‑cell design restores full mobility for daily office work and study sessions.

Voltage match decides fit

The single specification that determines compatibility is the 14.8 V output; the battery must match the laptop’s charging circuit exactly. Only systems listed with HS03, HS04, HSTNN‑LB6U, HSTNN‑LB6V, HSTNN‑DB7I or the 807956 and 807957 part numbers will recognise and charge this pack correctly. Using it in a machine that expects a different voltage risks damage or no power at all.

33 Wh capacity for light workloads

At 33 Wh the pack comfortably powers web browsing, document editing and video playback for several hours on a single charge. It runs out quickly under sustained loads such as gaming, rendering or heavy multitasking where the CPU and GPU draw peak power. Users who need all‑day runtime away from a socket should consider a higher‑capacity alternative or carry a charger.

Questions about this item

What does the 33Wh rating mean for daily use?

The 33Wh capacity at 14.8V stores enough energy for typical office tasks on compatible HP models; actual runtime depends on screen brightness, workload and battery health.

How does the 14.8V output match the original HS03 and HS04 batteries?

This replacement delivers the same 14.8V nominal voltage as the original HS03 and HS04 packs, so the laptop's power management sees no difference.

Will the 4-cell pack fit my 15-AY or 15-BA chassis without modification?

The battery uses the standard HS03/HS04 form factor with four A-grade cells, matching the original mounting points on the listed 15-AY, 15-BA and 17-X models.
