Direct replacement for HP EliteBook

The LXHY CC03XL is a 53Wh 11.55V lithium-ion battery built to match original part numbers including HSTNN-DB9Q and L77608-2C1. It fits HP EliteBook 830, 835, 840 and 845 G7 and G8 models along with ZBook Firefly 14 G7 and G8 and ProBook 635 Aero G7 and G8. The 4400mAh cell restores factory runtime for daily workloads.

Upgrades worn or failed original packs

When an original battery no longer holds charge or shuts down under load this unit restores full mobility without adapter dependence. The jump is worth it when the laptop shows reduced capacity warnings or cannot complete a typical work session unplugged. Certified CE FCC RoHS protection circuits guard against short circuit overheating and overload.

Fits standard 14-inch business chassis

The black pack seats in the existing battery bay using the laptop’s native latch mechanism and requires no additional cabling or firmware updates. It frees the user from tethered operation and supports hot-swap on models that allow it. Buyers needing higher capacity than 53Wh or compatibility with x360 convertible variants should verify fit before purchase.
