Replacement Battery for HP Pavilion 14/15/17-ab

This 41Wh lithium-ion pack replaces the original KI04 cell in compatible HP Pavilion 14-ab, 15-ab, 15-an and 17-g laptops. It delivers 14.8 volts from four premium Grade A cells and matches part numbers such as 800049-001, HSTNN-LB6S and TPN-Q158. The unit is new and certified to CE, FCC and RoHS safety standards.

Black Polymer Housing with Internal Cell Layout

The battery fits the existing bay without extra brackets or cables, so installation follows the standard removal procedure for the listed Pavilion models. A black finish matches the original chassis colour. Connectors align with the motherboard header, ensuring a secure lock when the pack is seated.

Capacity Limited to 41Wh and 14.8V Output

Runtime depends on the laptop's power draw, screen brightness and active peripherals, so heavy workloads will drain the pack faster than light browsing. The four-cell design cannot be expanded, and the fixed voltage suits only systems that specify 14.8V. Buyers needing higher capacity or a different voltage must select another part.
