What this battery replaces

The PISKEKAT VS03XL is a 52Wh 11.55V lithium-polymer pack built for HP Envy 15-as and 15t-as series notebooks. It matches the original VS03XL VSO3XL HSTNN-UB6Y TPN-I125 part numbers and the 849047-541 849313-850 849313-856 service codes. Buyers who need a different voltage or capacity should look elsewhere.

The specification that decides fit

Capacity is 52Wh at 11.55V with a three-cell Li-polymer layout. That combination fixes run-time and physical thickness; a 41Wh or 4-cell alternative will not seat correctly in the Envy 15-as chassis. Verify the original battery label shows VS03XL or one of the listed service codes before ordering.

How it fits the build

The pack slots into the existing battery bay using the original screw points and connector, so no adapter or cable modification is required. It restores mobile operation for the supported Envy models and frees the user from permanent AC tethering. Systems outside the 15-as and 15t-as families cannot use this battery.

Questions about this item

How long will the 52Wh capacity last on my HP Envy 15-as series laptop?

The 52Wh rating measures total energy storage. Actual runtime depends on your screen brightness, workload, and power settings, but the three-cell lithium-polymer pack is designed to match the original battery's endurance for this model range.

Does the 11.55V voltage match the charging circuit in my HP Envy 15t-as100?

Yes. The 11.55V output is the exact nominal voltage specified for the VS03XL part numbers (849313-856, 849047-541, HSTNN-UB6Y) used in the Envy 15-as series, so the laptop's charging controller will recognise and manage it correctly.

Will this VS03XL battery fit the internal bay of my HP Envy 15-as043cl without modification?

It is built to the VS03XL form factor (3ICP7/61/80 cell layout) and weighs about 0.69 lb, matching the original battery's shape and mounting points for the listed Envy 15-as models including the 15-as043cl.
