Build quality and daily use

The pack is certified to UL, CE, FCC and RoHS standards with built-in protection against short circuit, over-voltage, over-current and internal overheating. Two screwdrivers are included so you can open the chassis and swap the old battery without hunting for tools. Rated for up to 500 recharge cycles, the unit weighs 9.1 ounces and measures 11.1 by 4.45 by 1.42 inches.

Capacity and voltage match

The decisive specification is the 41.5 Wh capacity at 11.55 V; your HP Envy or M7 notebook requires exactly these values for correct charge reporting and runtime. Buyers whose laptop calls for a different watt-hour rating or voltage cannot use this pack.

Questions about this item

What voltage does the 41.5Wh SG03XL battery operate at, and what does that cap in practice?

The battery runs at 11.55V, which matches the original HP Envy 17-U and M7-U series power delivery specification and limits peak draw to the laptop's designed envelope.

What physical dimensions and weight must the chassis accommodate for the SG03XL replacement?

The pack measures 11.1 x 4.45 x 1.42 inches and weighs 9.1 ounces, fitting the existing battery bay on compatible HP Envy 17-U and M7-U models.

How is the SG03XL installed, and which step do people often miss?

Remove the bottom case screws, disconnect the old pack connector, fit the new battery, reconnect the cable, then re-secure all screws; the step often missed is fully seating the connector before closing the case.
