Compatible replacement battery for HP X360 310 G2

This 3-cell lithium-ion unit replaces the original HV03XL pack in the HP X360 310 G2 convertible laptop. It matches the OEM part numbers 817184-005, 818418-421, HSTNN-LB7B and HV03048XL-PR. The battery is new and ships from a US-based supplier. Buyers with different HP models or non-310 G2 chassis should verify compatibility before ordering.

Electrical limits of the 11.4 V 4050 mAh pack

The cell chemistry delivers 11.4 volts and 4050 milliampere-hours across three lithium-ion cells. Capacity and voltage are fixed by the pack design and cannot be expanded. Runtime will vary with screen brightness, workload and power-management settings. Systems that require a higher voltage or a different cell count will not operate with this battery.

Internal fit and everyday handling

The pack is built to slot into the existing battery bay of the X360 310 G2 without adapters or cable changes. Its shape follows the OEM outline so the bottom cover reattaches normally. No external charger or mounting hardware is included because the laptop charges the pack internally. Users who need a hot-swap solution or a higher-capacity extended pack will need a different product.
