11.55 V 3-Cell Battery for HP Envy X360

This 11.55 V lithium-ion replacement battery fits HP Envy X360 17-bw0706nz, 17-bw0999na, 15-cp0014au and 15-cp0599na laptops. It delivers 52.5 Wh capacity across three premium cells. The pack is CE and RoHS certified for safety and environmental compliance. It ships new with a one-year warranty.

Suits owners of the listed Envy models needing

Buyers whose laptop model is not among the four part numbers above should look elsewhere, as fit and connector alignment are model-specific. The pack does not serve other HP series or third-party brands. Users requiring a different voltage or cell count must select another part.

52.5 Wh capacity decides runtime

The 52.5 Wh rating determines how long the laptop runs on a single charge under your workload. Verify that your original battery shows the same watt-hour value before ordering. A mismatched capacity can change runtime and charging behaviour.
