Replacement battery for HP Pavilion 15-au and 15-aw

This 41Wh lithium-ion pack replaces the original BP02XL in compatible HP Pavilion 15-au and 15-aw notebooks. It fits models such as 15-AU063NR, 15-AU057CL, 15-AW053NR and the wider 15-AW000 series. The two-cell design delivers 7.7V and matches the factory part numbers including 849909-850 and HSTNN-LB7H. Buyers with other HP series or non-listed part numbers cannot use this unit.

Steady discharge from a two-cell lithium-ion pack

The 41Wh capacity supports typical office and web workloads across a full charge cycle without the voltage sag seen in smaller cells. Lithium-ion chemistry maintains consistent output until the pack nears depletion, avoiding the sudden drops that disrupt unsaved work. The 7.7V nominal rating aligns with the platform power management, so the notebook reports accurate remaining time. Systems that demand higher sustained wattage than this pack can supply will throttle earlier.

New condition with CE and FCC safety marks

Supplied as 100% new, the battery carries CE and FCC certification for electrical safety and environmental compliance. The connector layout matches the original BP02XL pin-out, allowing direct installation without adapters or cable modification. Physical dimensions follow the OEM specification so the pack seats flush in the battery bay and the latch engages securely. Notebooks that use a different battery form factor or voltage will not accept this replacement.

Questions about this item

Does the 2-cell 41Wh lithium-ion pack run hotter or draw more power than the original battery during all-day use?

It matches the original 7.7V 41Wh specification, so heat output and power draw stay the same as the factory battery under identical workloads.

What must I already own for this BP02XL replacement to work in my laptop?

A compatible HP Pavilion 15-au or 15-aw series notebook such as the 15-AU063NR, 15-AU057CL, 15-AW053NR or any model listed in the compatible P/N range.

Will this 7.7V 2-cell battery function correctly alongside the original AC adapter and charging circuit in an older 15-AU023CL?

Yes — the voltage, capacity and connector match the HSTNN-LB7H and 849569-421 part numbers used by that model, so charging and reporting work without changes.
