Replacement battery for HP Envy 17-u series
The Hecales SG03XL is a new 3-cell lithium-polymer pack rated at 11.55 V and 41.5 Wh. It matches the form factor and connector of the original HP batteries used across the Envy M7-U and 17-u model families, including the 17-u011nr, 17-u108ca, 17-u163cl and 17-u273cl variants. The black casing aligns with the OEM colour scheme.
Upgrades worn or failed OEM packs
This unit replaces HP part numbers such as 849048-421, 849049-421, 849314-850, 849315-850, HSTNN-LB7E, HSTNN-LB7F and TPN-I126. The jump is worth it when the original cell no longer holds a useful charge or shows swelling. Verify the connector position and cable length against the product image before ordering, as physical layout can differ between sub-models.
41.5 Wh capacity for typical mobile workloads
The 3-cell design delivers 41.5 Wh at 11.55 V, providing enough energy for everyday office tasks, web browsing and media playback on compatible 17-inch Envy notebooks. Runtime will fall short for sustained high-load scenarios such as gaming, video rendering or continuous virtualisation. Buyers needing significantly longer unplugged time should look for a higher-capacity alternative if one exists for their specific chassis.

Questions about this item
Does the SG03XL use the same connector layout and cable length as the original HSTNN-LB7E battery in my HP Envy 17-u163cl?
The supplier advises opening the laptop case to compare the connector location, type and cable length against the product image before ordering.
Which screw or latch secures the battery once the back cover is off an HP Envy M7-U109DX?
Disconnect the old battery cable from the motherboard first, then remove any securing screws or brackets before lifting the pack out.
How many full charge cycles will the 41.5Wh lithium-polymer pack last before capacity drops noticeably?
Capacity loss depends on usage patterns, temperature and charge depth; no cycle-life figure is published for this model.
