Drop-in replacement for HP Pavilion 14 15 17 series

This 41.9Wh 11.55V lithium-ion battery replaces the original HT03XL pack in compatible HP Pavilion 14 15 and 17 models. It delivers 3630mAh across three cells and ships with the screwdrivers needed for installation. The unit is new and rated for up to 500 recharge cycles over its service life.

Upgrade from a depleted or swelling original pack

When the factory battery no longer holds a useful charge or shows physical swelling this replacement restores full mobile runtime without modifying the laptop. The jump is worth it when the original cell count and voltage match the 3-cell 11.55V specification listed for your model. Builders who need a higher capacity pack or a different voltage should look elsewhere.

Limited by the laptop's internal charging circuit

The pack communicates with the host through the existing battery connector so charge management remains under firmware control. Cycle life depends on how the system balances the three cells during each charge. No external interface or faster-charging protocol is exposed beyond what the laptop already provides.
