Replacement for HP Envy 15-AS series

This 52Wh lithium-polymer battery operates at 11.55V and fits HP Envy 15-AS000 and 15-AS100 series laptops. It replaces part numbers VS03XL, HSTNN-UB6Y, 849047-541, 849313-850 and 849313-856. Buyers should verify the original battery part number before ordering.

Thermals noise and power draw

The 3-cell pack delivers 52Wh of capacity for typical mobile workloads. Lithium-polymer chemistry runs cool under normal use and produces no audible noise. Rated lifespan is about 300 to 500 discharge cycles per charge cycle.

Upgrade from worn original cells

This unit restores runtime lost to aging factory batteries in compatible Envy models. The jump is worth it when the original pack no longer holds a useful charge. It is not for users needing higher capacity than 52Wh or a different voltage.

Questions about this item

How do I install the VS03XL battery in my HP Envy 15-as series and what step is often missed?

Remove the bottom case, disconnect the old battery connector, fit the new 3-cell Li-polymer pack, then reconnect the cable before screwing the case back; the step often missed is disconnecting the connector first.

When will the VS03XL battery need replacement based on its rated cycle life?

The pack is rated for about 300 to 500 full charge cycles; expect to replace it once capacity drops below useful levels after that range.

What runtime limit appears first during sustained use of this 52Wh 11.55V battery?

The 52 watt-hour capacity sets the energy ceiling; under continuous load the battery will reach its voltage cut-off and shut down after depleting those 52Wh.
