In this review the PK03XL 56Wh replacement battery is assessed as a practical option for owners of the HP Spectre X360 13 family who need to restore run time without replacing the whole laptop. The battery is a direct-fit replacement for a long list of HP part numbers including 789116-005 and 788237-2C3, and the single biggest reason to buy is its combination of correct fit and built-in safety protections that mirror factory behavior. Installation tools are included, so users comfortable opening a back cover will find it straightforward to swap in the new pack.

Key Features

• 56Wh capacity: Provides a mid-length runtime comparable to the original battery for general productivity and web use.
• Smart safety protections: Built-in short circuit, over voltage and over current protection help keep the laptop and battery safer during regular use.

Who It's For

This replacement battery is well suited for owners of HP Spectre X360 13T and 13-series models and compatible Envy X360 convertibles who need a like-for-like swap to restore usable battery life. It is a good choice for DIY users who are comfortable opening the laptop back cover and verifying their original battery part number and shape before installation.

It is less appropriate for users who want an official HP-branded pack or those uncomfortable with self-installation; such users should consider professional installation services or authorized parts that include fitted service.
