Replacement battery for HP Pavilion and HDX laptops

This new 8-cell lithium-ion pack delivers 4400 mAh at 14.4 V for compatible HP Pavilion dv7 and HDX 18 series notebooks. It restores mobile power for users whose original battery no longer holds a useful charge. The unit is a direct replacement built to OEM specifications.

Practical limits of lithium-ion chemistry

Capacity of 63 Wh and 14.4 V output define the energy available per charge cycle. Lithium-ion cells gradually lose capacity over time and are sensitive to deep discharge and high temperatures. The pack includes protection against short circuit, overheat and overload but cannot exceed its rated voltage or capacity.

Verify model number and original battery part

Check that your laptop model appears in the compatibility list and compare the original battery part number such as 464058-121 or 464058-141. Confirm the original battery shows 14.4 V and 8 cells. A mismatch in voltage or cell count will prevent correct operation.

Questions about this item

Is the 4400 mAh version the only capacity offered for this model?

Yes, the MPL08218P-30 is supplied only as an 8-cell 4400 mAh 14.4 V pack rated at 63 Wh.

What run-time can I expect from the 63 Wh rating in a real laptop?

The 63 Wh pack replaces the original HP 8-cell battery and delivers comparable operating time per charge.

Does the battery use a proprietary HP connector or a standard interface?

It fits the same proprietary HP battery bay used by the listed Pavilion DV7, DV8 and HDX 18 models.
