Compatible HP and Compaq models

This replacement battery fits a wide range of HP Pavilion, G-series, HDX and Compaq Presario laptops. It matches original part numbers such as 485041-001, 497694-001 and 509458-001. Buyers should verify their exact model and original battery code before ordering.

Upgrading from a worn original pack

A six-cell lithium-ion unit restores runtime when the factory battery no longer holds a useful charge. The jump is worth it when the laptop otherwise meets daily needs but dies quickly on battery power. It does not add capacity beyond the original 4400 mAh specification.

Limits of the 10.8 V lithium-ion format

Capacity is fixed at 4400 mAh and voltage at 10.8 V, so runtime cannot exceed the original design envelope. The pack will not fit laptops that require a different cell count, voltage or physical shape. Users needing longer unplugged time must look for a higher-capacity alternative if the chassis allows it.

Questions about this item

What physical size and cell count must the replacement battery match for the HP Pavilion G50 series?

This unit is a 6-cell lithium-ion pack built to the same form factor as the original HP 485041-001 and 497694-001 batteries, so it fits the existing bay without adapters.

Which step do users often miss when installing the MPL08217P-30 in a Compaq Presario CQ60?

After sliding the pack into the bay until the latch clicks, many forget to let the smart chip calibrate by running a full charge-discharge cycle before relying on the battery gauge.

What component inside the Dr. Battery MPL08217P-30 will degrade first and require a new pack?

The six lithium-ion cells lose capacity over time; once runtime falls below useful levels the whole battery must be replaced, as individual cells are not user-serviceable.
