4-Cell 14.6 V Li-Polymer Battery

This 2600 mAh replacement battery fits select HP Pavilion 14, 15 and 17 models listed in the compatibility table. It is designed for owners who need a direct swap for an original HS03 or HS04 pack that no longer holds charge.

Replaces Original HS03 HS04 Packs

The unit substitutes part numbers such as 807956-001, 807957-001 and the longer HSTNN-LB6 series codes. The jump is worth it when the existing pack shows reduced runtime or swelling and the laptop model appears in the supported series list.

14.6 Volt Lithium-Polymer Chemistry

The 4-cell layout delivers a fixed 14.6 V output that the laptop's charging circuit expects. Capacity is limited to 2600 mAh, so runtime will match the original specification rather than extend it. Users needing higher capacity must choose a different pack.

Questions about this item

What physical space does the 14.6 V 4-cell pack need inside an HP Pavilion 15-ba chassis?

The pack measures 10.9 L x 0.9 W x 0.9 H inches and weighs 0.5 pounds, matching the original battery bay dimensions for the listed 15-ba models.

Which step do buyers most often miss when fitting the HS03/HS04 replacement?

Many skip verifying the exact part number — such as 807956-001 or 807957-001 — against the sticker on their old battery, so they order a pack that looks identical but is not compatible.

What replacement will this 2600 mAh Li-Polymer unit eventually require?

After the pack no longer holds sufficient charge, you will need another 4-cell 14.6 V Li-Polymer battery with the same part-number set (for example 807611-121 or HS04XL) to restore full runtime.
