Replacement battery for HP Envy 15-u series

This Dr. Battery MPL08298P-27 unit replaces the original HP HSTNN-LB6L and NP03XL packs used in multiple Envy 15-u models. It is built with lithium polymer cells rated at 11.4V and 3520 mAh for direct voltage compatibility. The black casing matches the factory form factor so it fits the existing battery bay without modification. Buyers who need a different voltage or connector layout cannot use this pack.

Sustained discharge and protection behaviour

A built-in smart control chip manages the discharge curve to deliver steady output during long sessions rather than only peak bursts. The circuitry includes short-circuit, overheat and overload safeguards that activate automatically when limits are reached. These protections help the cells maintain reliable performance across repeated charge cycles. Users who require uninterrupted operation beyond the rated capacity will need an additional power source.

Practical limits of the 11.4V lithium polymer

The nominal 11.4V output is fixed by the cell chemistry and cannot be adjusted for other laptop platforms. Capacity is listed as 3520 mAh with an alternative rating of 3720 mAh / 43 Wh noted by the manufacturer. The pack communicates with the host through the original HP battery connector only. Systems that expect a different pin-out or communication protocol will not recognise the battery.

Questions about this item

Does the 11.4V lithium-polymer cell generate noticeable heat during a full day of use?

The 11.4V lithium-polymer design runs at typical laptop-battery temperatures; no excess heat is reported under normal all-day operation.

Must my HP Envy 15 already have the HSTNN-LB6L or NP03XL part installed for this MPL08298P-27 to fit?

Yes — this pack replaces HP part numbers HSTNN-LB6L, HSTNN-UB6L, NP03XL and 760944-421, so one of those must be the original battery in your Envy 15.

Will the smart control chip charge correctly with the original 15-u000 series AC adapter?

The built-in smart chip supports quicker charging and standard protections, matching the OEM charging behaviour of the 15-u000 series adapter.
