Direct replacement for HP Envy 15-EP series

This lithium-ion battery restores original runtime to compatible HP Envy 15-EP models including the EP0005NP and EP0090TX. It matches the factory voltage of 11.58V and capacity of 6821mAh / 83Wh. The black pack fits the same chassis without modification.

No bundled accessories or software included

The package contains only the battery itself; no tools, screws or installation media are supplied. You reuse the existing hardware from the old pack. No firmware or driver updates are required for the battery to function.

83Wh capacity covers typical mixed workloads

At 6821mAh the cell delivers enough energy for several hours of office tasks, web browsing or video playback on a single charge. Heavy GPU loads or sustained high brightness will drain it faster, so keep the AC adapter handy for long sessions.
