Replacement battery for HP Pavilion 15-EG and 15-EH

This lithium-polymer pack is built to replace the original HW03XL unit in HP Pavilion 15-EG and 15-EH series laptops. It delivers 41.04Wh at 11.34V from three cells rated at 3440mAh. The part suits owners of listed models such as 15-eg0010nr, 15-eg0073cl and 15-eh0090wm who need a direct swap.

Installation and common issues

Fitting requires opening the chassis, disconnecting the old pack and seating the new connector firmly on the motherboard header. A loose plug is the main cause of a no-power or intermittent-charge symptom after replacement. Using the original charger and allowing a full first cycle helps the protection circuit calibrate correctly.

Capacity and voltage match

The decisive figure is 41.04Wh at 11.34V; any replacement must match both values or the laptop will not recognise the pack. This unit meets that exact rating and carries CE, UL, FCC and RoHS certification with a rated life beyond 500 cycles. It is not for machines outside the listed Pavilion 15-EG and 15-EH families or for users needing a higher-capacity alternative.

Questions about this item

How can I verify the NShi HW03XL battery is working correctly after installation?

After fitting the HW03XL, power on the HP Pavilion 15; the system should recognise the 11.34 V 41.04 Wh pack and charge using the original charger. The supplier states every unit passes factory testing with built-in circuit protection and is rated for more than 500 recharge cycles.

What is included with the NShi HW03XL battery and what must I source separately?

The package contains the HW03XL 3-cell lithium-ion battery only. You will need to reuse your existing screws, brackets and cables, and you must use the laptop's original charger for charging.
