Compatible replacement for HP HDX 18

This 8-cell lithium-ion battery replaces the original power source for HP HDX 18, HDX 18T and a wide range of Pavilion DV7 models. It delivers 14.4 volts and 4400 mAh capacity for users who need a direct swap without modification. The black casing matches the factory appearance and fits the existing battery bay.

Steady output through an integrated smart chip

The built-in control chip manages charging current to reduce heat buildup during extended sessions. It balances cell voltage across all eight cells so capacity remains consistent from the first minute to the last. Short-circuit, overheat and overload protections activate automatically when thresholds are exceeded.

Limited by the 14.4 V platform and 63 Wh rating

The 14.4 volt nominal voltage fixes the energy ceiling at 63 watt-hours, so runtime scales directly with the laptop's power draw. Systems that demand higher peak currents will hit the pack's current limit before the cells are depleted. Buyers who need more storage for longer unplugged time cannot exceed this chemistry ceiling.

Questions about this item

Does the 8-cell 14.4V 4400mAh battery run hot or draw heavy power during all-day use?

The lithium-ion pack is rated at 63Wh and includes a smart control chip that manages charging current and provides overheat and overload protection for stable daily operation.

What must I already own for the MPL08218P-21 to work in my laptop?

You need an HP HDX 18, HDX 18T or a compatible Pavilion DV7 series model listed in the compatibility table, plus the original battery bay and charging circuitry intact.

Will this 14.4V replacement work alongside the original AC adapter I still use?

Yes, the battery matches the 14.4V output of the original packs such as HSTNN-C50C and HSTNN-DB75, so your existing charger will charge it normally.
