Replacement battery for HP Spectre x360 13‑AP series

This 61.4Wh lithium‑ion pack replaces the original SP04XL cell in HP Spectre x360 Convertible 13‑AP and 13‑AP0XXXTU models. It delivers 15.4V from four cells and matches part numbers including HSTNN‑OB1B and L28764‑005. The unit is new and certified to CE, UL, FCC and RoHS standards.

Capacity and daily headroom

At 3990mAh the battery supports typical mixed workloads such as document editing, web browsing and media playback for a full workday. Heavy multi‑tasking or sustained high‑brightness video will draw the charge down faster, so plan for a top‑up during long sessions. The rated 500 recharge cycles provide multi‑year service under normal use.

Upgrading from a worn original

When the factory cell no longer holds enough charge for a meeting or a commute, this replacement restores the laptop’s original runtime without hardware changes. It is not suited for larger 15‑inch Spectre models or for users who need a higher‑capacity pack beyond the 61.4Wh design.

Questions about this item

Will the 15.4 V SP04XL battery fit my existing HP Spectre x360 13-AP series motherboard connector?

Yes, the SP04XL uses the same interface as the original HSTNN-OB1B and HSTNN-IB8R packs, so it connects directly to the motherboard in 13-AP and 13T-AP000 models.

How can I verify the 61.4 Wh pack is charging correctly after installation?

The laptop should report 15.4 V and 3990 mAh in the BIOS or OS battery utility, and the charge LED will follow the normal pattern when the original charger is attached.

Does the box include any tools or cables, or is it just the 4-cell lithium-ion battery?

Only the SP04XL battery is supplied; no screwdrivers, cables or adapters are included, so you will need your existing charger and any case-opening tools.
