Replacement battery for HP Envy 13 series

The Beisite KC04XL is a lithium-ion battery rated at 15.4 volts and 53.2 watt-hours. It matches part numbers KC04XL, KC04053XL, TPN-W133, TPN-W136, HSTNN-DB8P and HSTNN-IB8K. Designed for owners of Envy 13-AG, 13-AH, 13-AR and 13M-AQ models who need a direct swap for a depleted original pack.

Black lithium-ion pack with standard connector

The battery ships in black and uses the same connector layout as the factory unit, so no adapter cables or soldering are required. A screw-hole pattern identical to the original ensures the pack sits flush in the chassis and the bottom cover reattaches without gaps. Lithium-ion chemistry provides stable voltage delivery throughout the discharge cycle.

Verify your exact model number before ordering

Check the label on your current battery or the sticker on the laptop base for a part number such as HSTNN-DB8P, HSTNN-IB8K, L08496-855, L08544-1C1 or L08544-2B1. Confirm the laptop model appears in the supported list, which includes Envy 13-AH variants like ah0001nk and AH1005TX, and Envy x360 13-AG variants like 13-ag0001nk and 13-ag0011au. This battery is not for Envy models outside the listed series or for units requiring a different voltage or capacity.

Questions about this item

What voltage does the KC04XL battery supply to the HP Envy 13?

The KC04XL delivers 15.4V, matching the original specification for compatible Envy 13-AG, AH, AR and 13M-AQ models.

Which screws and connectors must align when fitting the KC04XL into an Envy 13-AH?

The battery uses the original HSTNN-DB8P / HSTNN-IB8K screw-hole pattern and the same multi-pin connector, so it drops into the existing chassis cut-outs.

What is the first step when installing the KC04XL, and what do people often skip?

Disconnect the internal battery cable from the motherboard before removing the old pack; skipping this risks a short circuit.
