Direct HP laptop replacement

This 14.8V 4-cell lithium battery replaces a long list of HP spare part numbers including 807956-001, 807957-001, HS03, HS04 and HSTNN-LB6U. It fits HP Pavilion 14, 15 and 17 series notebooks such as the 15-AY039WM, 15-AY041WM and 15-AY009DX. Buyers needing a different voltage or a 3-cell pack cannot use this unit.

Steady discharge with circuit protection

Grade A cells deliver consistent output during extended sessions rather than only in short bursts. Built-in circuit protection guards against overcharge, over-discharge and short circuits, keeping voltage stable while the machine runs demanding tasks. The pack is also rated compatible with 14.4V systems, so it maintains proper regulation across the supported models.

Simple swap with no soldering

The battery slots into the existing bay using the original latch mechanism; no tools or soldering are required. Alignment tabs match the HP chassis exactly, so the connector seats on the first try. Installers who force the pack before the tabs click risk bending pins, and systems with a swollen old pack may need the bay cleaned first.
