Dr. Battery MPL08217P-28 4400 mAh replacement

This Dr. Battery MPL08217P-28 is a new 6-cell lithium-ion laptop battery rated at 10.8 V and 4400 mAh. It serves as a direct replacement for compatible Compaq Presario and HP Pavilion, G-series and HDX models. The pack includes an integrated smart control chip that manages charging and discharge cycles. Built-in protections guard against short circuit, overheat and overload conditions.

Suits owners of listed Compaq and HP notebooks

The unit fits the extensive range of models shown in the compatibility list, including Presario CQ40, CQ41, CQ45, CQ50, CQ60, CQ61, CQ70, CQ71 and HP G50, G60, G61, G70, G71, HDX 16 and Pavilion DV4, DV5, DV6 series. Buyers whose laptop is not on that list should look elsewhere, as fit and electrical matching cannot be assured. Anyone needing a higher capacity pack or a different voltage must choose another product.

10.8 V output voltage matches original specification

The single specification that decides suitability is the 10.8 V output, which must match the original battery voltage exactly. A mismatched voltage can prevent the notebook from starting or cause permanent damage to the charging circuit. Verify the voltage printed on your old battery before ordering to ensure correct compatibility.

Questions about this item

How many charge cycles will the 6-cell lithium-ion pack deliver before capacity drops?

The 6-cell lithium-ion design rated at 4400 mAh and 48 Wh is built to retain useful capacity for several hundred full cycles under normal use.

What stops the battery from running longer during an all-day workload?

The 4400 mAh capacity sets the runtime ceiling; once the stored charge is depleted the system must recharge.

Does the pack run hot or draw extra power when the laptop is used continuously?

The integrated smart control chip manages charging and discharge to limit heat rise and keep power draw stable during extended sessions.
