FOCUSTEC KI04 4-cell Li-ion battery

This new FOCUSTEC KI04 battery is a 14.8V 2200mAh 33Wh lithium-ion pack built for HP Pavilion 14-ab, 15-ab, 15-ak and 17-g00 series notebooks. It replaces original part numbers such as 800049-001, 800050-001, HSTNN-DB6T and the TPN-Q158 through TPN-Q163 families. Owners of compatible models can swap the old pack without tools and restore mobile runtime.

Internal protection and safety certifications

The pack uses Class A cells rated for around 500 recharge cycles and carries UL, CE, FCC and RoHS certifications. Built-in circuitry provides short-circuit, over-voltage, over-current, over-discharge and over-heat protection so the laptop charges safely and the battery does not degrade from common fault conditions. No additional mounting hardware is required; the original latch secures the pack.

Direct replacement for worn HP Pavilion packs

This unit is a straight swap for factory batteries that no longer hold charge or that trigger replacement warnings in the BIOS. It is not suited for laptops outside the listed Pavilion 14-ab, 15-ab, 15-ak and 17-g00 ranges, nor for users who need higher capacity than 33Wh. When the original pack falls below useful runtime, this battery restores the notebook to its designed mobility.

  • Extended lifespan with 500-plus recharge cycles
