Replacement Battery for HP Pavilion 15-DK

The NShi PG03XL is a new lithium-polymer battery rated at 52.5Wh and 11.55V. It is built to fit the HP Pavilion 15-DK series, including the 15-DK0125TX model, and replaces the original HSTNN-OB1I pack. Buyers who need a different voltage or a higher capacity will not be served by this unit.

Polymer Cell Construction and Connector Fit

The polymer cell design keeps the pack lightweight while matching the original form factor for a direct connector fit. No installation instructions are included, so the connector must be seated carefully during replacement. Improper handling can damage the battery or the laptop, and the supplier accepts no liability for errors made during fitting.

Capacity and Cycle Behaviour

The 52.5Wh rating defines the energy available per charge, and the supplier notes that peak runtime is reached after 2 or 3 full charge and discharge cycles. Using a low-quality third-party charger will shorten the usable life of the pack. Users who require longer unplugged sessions than this capacity allows should consider a higher-capacity alternative if one exists for their chassis.

Questions about this item

What voltage does the PG03XL battery deliver, and what capacity does that support?

The PG03XL supplies 11.55V with a 52.5Wh capacity, matching the original HSTNN-OB1I specification for compatible HP Pavilion 15-DK models.

Which HP Pavilion chassis does the PG03XL fit without modification?

It is built for the HP Pavilion 15-DK series, including the 15-DK0125TX, and uses the exact PG03XL form factor so it seats in the stock battery bay.

What is the correct connector orientation when installing the PG03XL, and why do some installs fail?

Align the keyed connector with the motherboard header before pressing it in fully; the most common error is seating it at an angle, which leaves pins unconnected and prevents charging.
