Dr. Battery 8-cell 14.4V replacement

The Dr. Battery MPL08218P-25 is an eight-cell lithium-ion pack rated at 14.4V and 4400mAh. It is built as a direct replacement for HP HDX 18 and HDX 18T notebooks as well as numerous Pavilion DV7 series models listed in the compatibility data. The unit ships new with a one-year warranty from the manufacturer.

Fits HP HDX and Pavilion DV7 chassis

This battery slots into the existing bay on supported HP laptops without adapters or cabling changes. It restores mobile operation for machines whose original packs have degraded, freeing the user from permanent mains connection. Verification of the original part number and voltage is recommended before installation.

Steady output through smart-chip regulation

An integrated control chip manages charge cycles to deliver consistent voltage across extended sessions rather than brief peaks. Protections against short circuit, overheat and overload activate automatically under sustained draw. The 63Wh capacity supports prolonged workloads while the cell chemistry maintains stable discharge characteristics.

Questions about this item

How long will the 4400 mAh 8-cell pack keep my HP HDX 18 running under a constant heavy load?

The 63 Wh rating gives a baseline; actual runtime depends on your laptop's power draw, so divide 63 Wh by the system's average wattage to estimate hours.

Does the built-in smart chip keep the 14.4 V pack cool and quiet during all-day charging and discharging?

The protection circuit prevents overheat and overload, which limits temperature rise; the battery itself has no fan, so it runs silently.

My original HP battery shows part number HSTNN-DB75 — will this Dr. Battery unit fit and connect without any extra cables?

Yes, HSTNN-DB75 is listed in the compatibility table, so the pack matches the connector and form factor of that original battery.
