Replacement 4-cell Li-ion battery

This new 4-cell lithium-ion battery is rated at 14.8V, 2800mAh and 41Wh and is built with grade A+ cells and a smart control chip. It replaces original HP part numbers including 800049-001, 800010-421, HSTNN-LB6R, HSTNN-DB6T, HSTNN-LB6S, KI04 and TPN-Q160 through TPN-Q162. Designed for HP Pavilion 14-AB, 15-AB, 15-AK, 15-AN and 17-G series laptops.

Cycle-life limit for daily use

The manufacturer rates the pack for over 1000 charge cycles, which sets the practical service horizon for a machine used every day. Built-in safeguards protect against short circuit, overheating and overloading, and the unit carries UL, CE, FCC and RoHS safety certifications. Capacity will gradually decline as the cycle count approaches that threshold.

Upgrade from a depleted original pack

This battery replaces an exhausted or failing factory pack that no longer holds a useful charge. The jump is worthwhile when runtime has dropped below what your workflow requires and the laptop chassis and charger are otherwise sound. It is not for buyers who need a higher-capacity design than the original 41Wh specification.

Questions about this item

How do I know if this 2800mAh 41Wh KI04 battery fits my HP laptop?

Match your original part number against the list — 800049-001, 800010-421, HSTNN-LB6R, HSTNN-DB6T, HSTNN-LB6S, TPN-Q158, TPN-Q159, TPN-Q160, TPN-Q161, TPN-Q162 or KI04 — and confirm your model is among the Pavilion 14-AB, 15-AB, 15-AK, 15-AN or 17-G series shown.

What does the 41Wh rating mean for daily runtime?

The 41 watt-hour capacity at 14.8 volts delivers roughly 2800 milliampere-hours; actual runtime depends on your laptop's power draw, screen brightness and workload, but the pack is designed to meet or exceed the original battery's endurance.

Does the 14.8V 4-cell design charge through the standard HP connector?

Yes — the pack uses the same voltage and cell count as the factory 4-cell HP batteries listed, so it charges and reports capacity through the laptop's normal charging circuit without adapters.
