Replacement Battery for HP Pavilion and Envy

This new lithium-polymer battery delivers 52.5Wh at 11.55V across three cells. It fits HP Pavilion 15-Cx and Envy X360 15-Cn 15-Cp 17-Bw series laptops. The pack replaces part numbers including Sr03xl and L08855-855.

Steady Capacity Under Daily Load

The 4550mAh rating supports extended work sessions without rapid voltage sag. Lithium-polymer chemistry maintains consistent output during sustained use rather than only in short bursts. Users can expect reliable runtime for typical productivity and gaming workloads.

Direct Fit With Original Mounting Points

The unit matches the original form factor so it seats securely in the existing battery bay. No adapters or modifications are required for installation. Buyers needing a different voltage or higher capacity will need an alternative solution.

Questions about this item

Does the 3-cell 52.5 Wh lithium-polymer pack run hotter than the original during all-day gaming?

The 11.55 V 3-cell design matches the factory voltage and cell count, so thermal behaviour stays within the laptop's original cooling limits.

Do I need a specific HP part-number charger such as the HSTNN-DB8Q for this Sr03XL to charge correctly?

Any genuine HP adapter rated for 11.55 V output will charge the 4550 mAh pack; no extra accessories are required.

Will this 11.55 V battery fit my Envy X360 15-CP series that currently uses an HSTNN-IB8L pack?

Yes — the Sr03XL replaces HSTNN-IB8L, L08855-855 and TPN-C133 packs used in the 15-CP and 17-BW models listed.
