BFKK VS03XL 52 Wh replacement battery

This BFKK VS03XL is a new 52 Wh laptop battery built for HP Envy 15-AS series notebooks including the 15-AS133CL, 15-AS020NR and 15-AS043CL. It replaces part numbers VS03XL, HSTNN-UB6Y, 849047-541 and 849313-850. The pack ships with two screwdrivers and an instruction sheet for straightforward installation.

3-cell 11.55 V design with 1000-cycle rating

The three-cell lithium-ion layout delivers 11.55 V and 52 Wh, matching the original capacity for everyday office work, web browsing and media playback. Rated for up to 1000 recharge cycles, it maintains useful runtime across a long service life. Heavy workloads such as sustained gaming or video rendering will deplete the charge faster than light use.

Direct-fit connector for listed Envy models

The battery uses the exact connector and form factor required by the compatible Envy 15-AS and 15T-AS chassis, so no adapter or modification is needed. It will not fit laptops outside the listed part-number range, and it does not support fast-charge protocols beyond the system’s standard charging circuit. Buyers needing a higher-capacity pack or a different voltage should verify their service tag before ordering.
