GreenTechLLC CM03XL 11.1V 50Whr 3-cell laptop battery

Compatible HP EliteBook replacement battery

This GreenTech CM03XL is a new 3-cell lithium-ion pack built to replace the original battery in HP EliteBook 740, 745, 750, 755, 840, 850 G1 and G2 models, plus the EliteBook Folio 9480m and ZBook 14 G2. It restores mobile power for professionals who need their notebook to run away from a wall socket. The black casing matches the OEM look and fits the existing battery bay without modification.

Deciding specification: 11.1V 50Whr capacity

The single figure that determines fit is the 11.1V 50Whr rating, which matches the OEM part numbers CM03, CM03XL, CM03050XL-PL, E7U24UT, E7U24AA, 716724-421 and 717376-001. If your service tag lists any of those part numbers, this pack will seat correctly and report the proper charge level to the BIOS. Buyers whose laptops require a different voltage or watt-hour rating cannot use this unit.

Sustained-load behaviour

Each cell is tested for stable current delivery and low self-discharge before shipping, so the pack maintains consistent voltage during long work sessions rather than sagging after a short burst. The built-in circuit protection guards against over-charge, over-discharge and short circuits, while CE, FCC and RoHS certifications confirm the safety circuitry operates within approved limits over the full discharge cycle.
