Li-polymer build with direct-fit mounting

The lithium-polymer chemistry allows a slim profile that matches the original chassis dimensions for the listed HP models. Direct-fit mounting uses the existing latch points on the 240, 245, 250, 255, 246 and 256 G2 or G3 series, plus the 14-r and 15-r families. No adapters or modifications are required.

Ready to install with no extra software

The package contains only the battery itself; no drivers, utilities or calibration tools are bundled. Installation is a simple mechanical swap that the notebook firmware recognises immediately. Buyers who need a multi-bay charger or an external power bank will not find those functions here.
