Dr. Battery MPL08218P-01 8-cell 4400 mAh 14.4 V laptop battery

Replacement battery for HP HDX 18 and DV7 series

This 8-cell lithium-ion pack replaces original HP batteries numbered 464058-121 through 464059-142. It fits HP HDX 18, HDX 18T and a long list of Pavilion DV7 models including dv7-1100, dv7-1245dx and dv7-3085dx. The unit ships new and carries a one-year warranty from the manufacturer.

Built-in smart control chip and safety protections

The integrated chip manages charging to reduce power draw and extend discharge time. It also provides short-circuit, overheat and overload safeguards so the battery operates safely during daily use. No extra software or cables are included in the package.

14.4 V 4400 mAh capacity limits runtime

At 63 Wh the pack delivers a fixed energy budget; heavy workloads or ageing cells will shorten each charge cycle. It cannot power laptops that require a different voltage or a higher watt-hour rating. Buyers needing longer unplugged time or a different form factor should look elsewhere.
