Replacement Battery for HP Envy 15-AS Series

The TAURKENAM VS03XL is a new lithium-ion laptop battery rated at 11.55V and 52Wh capacity. It replaces part numbers including VS03XL, HSTNN-UB6Y, 849313-850 and 849313-856. The pack uses quality cells and a smart protection circuit to deliver stable current and low self-discharge.

For owners of listed HP Envy models only

This unit fits the HP Envy 15-AS and 15T-AS series such as 15-AS133CL, 15-AS152NR, 15-AS182CL, 15-AS043CL and 15T-AS100 among others. Buyers with different HP chassis or non-HP laptops cannot use this battery. It is not a higher-capacity upgrade and does not support fast-charging protocols beyond the original specification.

Sustained discharge with circuit protection

Under continuous load the pack maintains steady voltage through its built-in protection board, limiting current spikes and preventing deep discharge.
