Dr. Battery MPL08234P-19 6-cell 10.8V 4400mAh laptop battery

Replacement Battery for Compaq Presario

This Dr. Battery MPL08234P-19 is a new six-cell lithium-ion pack built to replace the original power source in Compaq Presario CQ32, CQ42, CQ56, CQ57, CQ62, CQ630 and CQ72 notebooks. It also fits a wide range of HP models including the 2000, 630, 635, ENVY 17, G62, G72, Pavilion dm4-1050ca, DV3, DV5, DV6, DV7 and several g6 variants. The black casing matches the OEM appearance and installs without modification.

Voltage and Cell Limits

The pack delivers a nominal 10.8V from its six lithium-ion cells, which is the fixed operating voltage the laptop’s charging circuit expects. A smart control chip manages the charge cycle, providing quicker charging, lower power consumption and longer discharge time while enforcing short-circuit, overheat and overload protections. The battery will not function correctly in systems that require a different cell count or voltage, so verifying the original part number is essential before purchase.

Capacity and Runtime

Rated at 4400mAh and 48Wh, this battery supplies enough energy for typical office tasks, web browsing and media playback on the supported Compaq and HP laptops. Runtime scales with screen brightness, processor load and peripheral use; intensive workloads such as gaming or video rendering will deplete the charge more quickly. The one-year warranty covers defects in materials and workmanship under normal use.
