Direct Replacement for HP Envy 15-AS

This 11.55V 52Wh lithium-ion battery replaces part numbers VS03XL, HSTNN-UB6Y, 849047-541 and 849313-850. It fits the HP Envy 15-as series including models as000 through as101ng. The three-cell pack restores original runtime for compatible laptops.

Straightforward Swap with Basic Tools

Installation requires only a screwdriver to remove the bottom case and disconnect the old pack. The connector matches the original layout so no adapter is needed. Common issues arise if the battery ribbon cable is not fully seated or if the BIOS is not updated before first use.

52Wh Capacity for Daily Workloads

The 52Wh rating supports typical office tasks, web browsing and video playback for several hours. Heavy workloads such as rendering or gaming will drain the pack faster. Users needing all-day runtime away from mains power should consider a higher-capacity alternative if the chassis allows it.
