Replacement Battery for HP Envy 15-u Series

This lithium-polymer unit replaces the original HP batteries numbered HSTNN-LB6L, HSTNN-UB6L, NP03XL and 760944-421. It fits a long list of Envy 15-u models including the 15-u001na, 15-u002xx, 15-u010dx and 15-u011dx. Buyers with other HP chassis or different battery part numbers cannot use this pack.

Voltage and Capacity Limits

The cell chemistry delivers a fixed 11.4 V output with a rated capacity of 3520 mAh, which the manufacturer also lists as 3720 mAh or 43 Wh. The smart control chip manages charging current and provides short-circuit, overheat and overload protection. Systems that require a different voltage or a higher watt-hour rating will not operate correctly with this battery.

Matching the Original Part Number

The single specification that decides fitment is the exact HP part number printed on your existing battery. Verify that your original reads HSTNN-LB6L, HSTNN-UB6L, NP03XL or 760944-421 before ordering. If the label shows any other code, this unit is not compatible.

Questions about this item

Should I pick the 3520 mAh or the 3720 mAh version for my HP Envy 15?

The product lists 3520 mAh in the specifications and 3720 mAh in the highlights; both refer to the same MPL08298P-21 unit, so choose this single model.

What does the 11.4 V rating mean once the battery is installed?

It matches the original voltage required by the compatible HP Envy 15-u series, so the laptop will recognise and charge it normally.

Does the built-in smart chip limit charging speed or capacity in any way?

The chip manages quicker charging, lower power consumption, longer discharge time and adds short-circuit, overheat and overload protections.
