Compatible Replacement Battery

This 11.55 V 55.8 Wh lithium-ion unit replaces the original power pack in compatible HP Envy 17 and Envy x360 15 models. It matches part numbers such as 916368-541 and HSTNN-LB7U for a direct fit.

When The Swap Makes Sense

If the factory cell no longer holds a useful charge after hundreds of cycles, this new battery restores full runtime without servicing the whole machine. The jump is worth it when the laptop still meets your performance needs but tethering to a wall outlet defeats its portability.

Cycle Life And Chemistry Limits

Lithium-ion chemistry delivers up to 500 recharge cycles before capacity drops noticeably. Heat, deep discharges and constant full-charge storage accelerate that decline, so the practical lifespan depends on daily habits rather than the cell alone.

Questions about this item

Does the 11.55 V 55.8 Wh pack fit the HP Envy 17-AE and 17-BW chassis without modification?

It matches the original LK03XL form factor and the listed part numbers 916368-541, 916814-855 and HSTNN-LB7U for those 17-inch Envy models.

Which screw or latch step is most often missed when swapping the internal pack on an Envy 17?

Many installers forget to re-engage the battery retention latch after seating the connector, leaving the pack loose inside the 17-inch chassis.

After roughly how many full charge cycles should I expect the 4835 mAh cell to drop below 80 % capacity?

The manufacturer rates the lithium-ion cells for up to 500 recharge cycles over the life of the battery before significant capacity loss.
