Replacement battery for HP Envy X360 13 series

This 15.4 V lithium-ion pack replaces the original KC04XL cell in HP Envy X360 13-AG, 13-AR, 13-AH and 13-AQ convertible notebooks. It matches the factory voltage and connector layout so the laptop recognises it immediately. The unit ships new and carries CE and UL safety certifications.

Single voltage rail and fixed connector

The battery delivers only the 15.4 V rail required by the supported Envy models; it cannot be used in laptops that expect a different voltage or a different pin-out. No onboard charge controller is included, so the host system manages all charging logic. Compatibility is limited to the part numbers and model series listed in the specifications.

53.2 Wh capacity for typical ultraportable workloads

At 53.2 Wh the pack supplies enough energy for a full day of light productivity, web browsing and media playback on a 13-inch convertible. Heavier sustained loads such as video rendering or gaming will drain the charge faster and may require mid-day recharging. The four-cell design keeps the profile slim while providing the rated 3454 mAh at the nominal voltage.
