Replacement Battery for HP HDX 18
This 8-cell lithium-ion battery operates at 14.4V with a 4400 mAh capacity, delivering 63Wh of energy. It is built as a direct replacement for the original HP batteries used in HDX 18, HDX 18T and a wide range of Pavilion DV7 models. The unit is supplied new and includes a one-year warranty.
Upgrading from Depleted or Lower-Capacity Originals
The battery replaces OEM part numbers such as 464059-221, 464059-222, 464059-251, 464059-352, 480385-001, 486766-001, 497705-001, 516355-001 and 534116-291. The jump is worth it when the original pack no longer holds a useful charge or when a lower-capacity 6-cell unit was fitted from the factory.
Fits HP HDX 18, HDX 18T and Listed DV7 Chassis
The pack matches the physical footprint and connector layout of the factory batteries for the models listed in the compatibility table. A built-in smart control chip manages charging, provides short-circuit, overheat and overload protection, and helps extend discharge time. Buyers who need a different voltage, a higher cell count or compatibility with non-HP laptops should look elsewhere.

Questions about this item
Does the 8-cell lithium-ion pack fit the original battery bay on an HP HDX 18 or Pavilion dv7 without modification?
The pack is built to the same form factor as the OEM batteries listed under part numbers 464059-221, 464059-222 and 480385-001, so it seats directly in the factory compartment.
What is the correct sequence to install the 14.4 V 4400 mAh battery and avoid the common loose-connector issue?
Power off the laptop, disconnect the AC adapter, slide the release latch, insert the pack until the latch clicks, then reconnect the AC adapter and allow a full charge before first use.
When should the 63 Wh battery be replaced based on the built-in smart chip behaviour?
The smart control chip reports declining capacity through the OS battery meter; when runtime drops well below the original 4400 mAh rating or the pack no longer holds charge, replace it.
