Replacement for HP Pavilion batteries

The PISKEKAT KI04 800049-001 is a brand-new lithium-ion laptop battery built for HP Pavilion 14-ab, 15-ab, 15-an and 17-g series notebooks. It replaces original HP part numbers including 800010-421, 800049-001, 800050-001, 800009-241 and 800009-421. The pack ships with an instruction sheet for straightforward installation.

Upgrade from worn original cells

This unit replaces a depleted factory battery when runtime has dropped or the system no longer holds a charge. The jump is worth it when the original pack reaches the end of its cycle life or shows swelling, letting the notebook return to portable use without mains dependency.

33 Wh capacity with 1000-cycle rating

The 4-cell, 14.8 V, 33 Wh, 2200 mAh design delivers typical daily runtime for web browsing and office tasks on compatible Pavilion models. Rated for up to 1000 recharge cycles, it provides long-term headroom before another replacement is needed. Heavier workloads will drain the pack faster and reduce time between charges.

Questions about this item

Does the KI04 800049-001 battery fit the HP Pavilion 15-ab157nr and 17-g119dx models?

Yes, this 33WH 14.8V 4-cell lithium-ion pack replaces part numbers 800049-001, 800010-421, HSTNN-LB6R, HSTNN-DB6T, HSTNN-LB6S and the TPN-Q158 through TPN-Q162 series used in those Pavilion 15-ab and 17-g laptops.

What is the correct way to install the KI04 battery and what step do people often miss?

Power off the laptop, disconnect the AC adapter, remove the old pack, insert the new KI04 unit until the latch clicks, then charge it to 100 % before first use — the calibration charge is the step most users skip.

When will the KI04 33WH battery need replacement and how many cycles does it support?

The manufacturer rates the pack for up to 1000 recharge cycles; after that capacity will drop below useful levels and a new battery will be required.
