Compatible replacement for HP Dragonfly G2

This new lithium-ion battery replaces the original EP04XL and L52581-005 units in the HP Dragonfly G2 and Dragonfly Max. It uses a 4 cell design rated at 7.7V and 7000mAh to restore factory-level runtime. The part is built for owners of those specific ultraportables who need a direct drop-in power source.

Upgrade from depleted or failing original packs

The jump is worth it when the original pack no longer holds a useful charge or triggers replacement warnings. Swapping in this 4 cell unit restores full mobility without requiring a different charger or firmware change. It is not for users whose batteries still meet daily workload needs or who require a higher capacity than 7000mAh.

Steady output through a full workday

The 7.7V chemistry delivers consistent voltage across the discharge curve rather than a brief peak followed by rapid sag. Four cells share the load to limit heat buildup during extended use such as video calls or document editing. Runtime scales with screen brightness and CPU load, so heavy multitasking will drain the 7000mAh reserve faster than light browsing.

What is the step people skip when installing the 7.7 V 7000 mAh unit?

After seating the battery and securing the screws, the firmware battery gauge must be recalibrated by running a full charge-discharge cycle before relying on the percentage readout
