SG03XL 41.5Wh Li-Polymer battery

The PISKEKAT SG03XL is a new 11.55V rechargeable battery built with Grade A cells. It replaces the original HP Envy M7-U and 17-U series power packs including part numbers 849048-421, HSTNN-LB7E and TPN-I126.

Installation and common issues

The package includes free screwdrivers so the swap can be done with basic tools. Carefully disconnect the old pack before fitting the new one; forcing the connector or reversing polarity can damage the motherboard.

Capacity and headroom

The 3-cell, 41.5Wh design restores factory runtime for everyday office work and media playback. Heavy loads such as sustained gaming or video rendering will drain the pack more quickly and may require a mains connection for longer sessions.
