Futurebatt HW03XL is a direct-replacement 3-cell lithium-ion battery that restores full portable power to compatible HP Pavilion 15 and 17 laptops.

This pack matches the original battery's form factor while using higher-quality cells, includes safety certifications, and arrives backed by a 12-month warranty for peace of mind.

Which HP laptops will this battery work with?

The HW03XL is designed for a wide range of HP Pavilion 15 and 17 series models. It replaces numerous OEM part numbers so you can confidently fit it into systems that list HW03XL or listed replacement codes.

How long will the Futurebatt HW03XL last on a charge and over time?

On a full charge the 41.04Wh capacity provides similar runtime to the original battery under comparable usage, and the pack uses quality cells rated for many cycles. With typical use you should expect stable performance for hundreds of charge cycles before noticeable capacity loss.

• Turn off the laptop and remove mains power before replacing the battery.
• Compare the old battery part number (e.g., HSTNN-IB90, L96887-...) or model series to this listing.
• If unsure, check the system BIOS battery ID or the service manual for your exact Pavilion model.
