Replacement battery for HP Envy 13

This 53.2Wh lithium-ion unit replaces the original KC04XL pack in HP Envy 13 AH and Envy x360 13 AR models. It delivers 15.4V from a 3454mAh cell count and matches the listed part numbers including TPN-W136 and HSTNN-DB8P. The black casing fits the same battery bay without modification.

Who this suits and who it does not

Owners of the listed Envy 13-AH, Envy x360 13-AR and Envy 13-AQ laptops can restore runtime with this direct-fit replacement. Buyers whose machine uses a different voltage or connector, or who need a higher-capacity pack than 53.2Wh, should look elsewhere.

Deciding specification — voltage and capacity

The battery operates at 15.4V and stores 53.2Wh. If the original pack shows the same voltage and watt-hour rating, this part will work; a mismatch on either figure means it will not.

Questions about this item

Will the KC04XL fit inside the HP Envy 13-AH0010TX chassis without modification?

Yes, the KC04XL matches the original TPN-W136 and HSTNN-IB8K part numbers for the Envy 13-AH series, so it seats in the factory battery bay with no chassis changes.

What is the common installation mistake when swapping the KC04XL in an Envy X360 13-AR?

Many users forget to disconnect the internal battery cable before removing the bottom cover; always unplug the old pack first to avoid a short on the 15.4V rail.

When should I replace the KC04XL based on its 53.2Wh rating?

Plan a replacement when the pack no longer delivers close to 53.2Wh on a full charge — runtime will fall noticeably below the original 3454mAh capacity.
