52Wh Li-polymer replacement battery

This 52Wh Li-polymer battery operates at 14.8V and delivers 3500mAh of capacity. It is built as a direct drop-in replacement for the original EL04XL cell in HP ENVY TouchSmart 4-1000, 4-1100 and 4-1200 series ultrabooks. The black pack restores factory-equivalent run time for mobile professionals and students who need their notebook to last through a full workday away from a desk.

Snap-in fit with OEM part-number match

The battery casing mirrors the original dimensions and latch positions so it clicks into the chassis without tools or adapters. It replaces part numbers including EL04XL, HSTNN-IB3R, HSTNN-UB3R, 681879-541 and 681949-001, ensuring the connector alignment and screw holes line up exactly as the factory unit did. No cable rerouting or firmware updates are required after installation.

Restores mobility lost to an aged original cell

When the original pack no longer holds enough charge for a meeting or a commute, this unit returns the laptop to its designed unplugged endurance. The upgrade is worth it whenever the existing battery reports significantly reduced capacity or triggers a replacement warning in the BIOS. It does not add extra capacity beyond the original 52Wh specification, so users seeking longer run times than the machine originally provided will need a higher-capacity alternative if one exists for this chassis.
