Compatible HP Envy 17-inch replacement battery

Straightforward internal swap with common pitfalls

Installation requires opening the chassis and disconnecting the old pack before fitting the new one; most Envy 17 models use internal screws and a ribbon cable. Common issues include forgetting to detach the connector gently, which can damage the motherboard header, and not seating the battery flush so the bottom cover will not close. Ensure the replacement part number matches the label on your original unit exactly.

Verify the exact model

Check the sticker on your current battery for SG03XL or one of the listed OEM codes such as 849048-421 or HSTNN-LB7F. Confirm your laptop belongs to the HP Envy M7-U or 17t-U000 families; other Envy 17 generations use different packs. This unit is not for ultrabooks, detachable tablets or models requiring a 3-cell or 6-cell configuration.

Questions about this item

How can I verify the SG03XL battery is working correctly after installing it in my HP Envy 17-U011NR?

After installation the laptop should power on immediately and the OS battery meter should report 15.55 V and 41.5 Wh without sudden percentage jumps during the first few charge cycles.

What is included with the SG03XL battery and what must I supply myself?

The package contains the 4-cell Li-ion battery only; no tools, screws or AC adapter are supplied, so you will need a small Phillips screwdriver to open the battery compartment.

Which SG03XL version should I choose for an HP Envy M7-U109DX W2K88UA?

This single SG03XL variant replaces part numbers 849048-421, 849049-421, 849314-850, 849315-850, HSTNN-LB7E and HSTNN-LB7F, covering the M7-U109DX and all other listed Envy 17 models.
