Drop-in replacement for HP Envy 17-inch M7 series

This 41.5 Wh lithium-polymer battery matches the original 11.55 V specification and fits HP Envy M7-U, 17t-u100 CTO and 17-u000 notebooks. It replaces part numbers SG03XL, 849048-421, 849314-850 and HSTNN-LB7E among others. Two screwdrivers are included for installation.

Steady output with built-in protection circuits

Overcharge, overdischarge, over-temperature and short-circuit safeguards maintain stable voltage during long work sessions. The three-cell pack is rated for up to 500 recharge cycles, so capacity holds up through daily charge and discharge routines.

Upgrade when the original pack no longer holds

If runtime has fallen below what a fresh 41.5 Wh cell can deliver, this unit restores factory-level endurance. It is not suited for smaller Envy chassis or models that require a different voltage or connector layout.

Questions about this item

Does the SG03XL run hot or draw extra power during all-day use?

The 11.55 V 41.5 Wh lithium-polymer pack includes over-temperature and short-circuit protection, so it stays within normal thermal limits during continuous operation.

What must I already own to install this battery?

You need a compatible HP Envy M7-U or 17t-u100 CTO notebook and a small Phillips screwdriver; two screwdrivers are included in the box.

Will the SG03XL work in my older HP Envy 17-u153nr?

Yes — the 17-u153nr is listed among the supported models, so the battery fits and communicates correctly with that chassis.
