Direct Replacement Battery

The Dr. Battery MPL08217P-01 is a new six-cell lithium-ion pack rated at 10.8V and 4400mAh. It matches the OEM specifications for a wide range of Compaq Presario CQ and HP Pavilion DV series laptops including models 40, 41, 45, 50, 60, 61, 70 and 71.

Sustained Runtime Behaviour

Built-in smart control circuitry manages charging cycles to reduce power consumption and extend discharge time under continuous load. Integrated protection guards against short circuit, overheat and overload events so the pack delivers stable voltage throughout long work sessions without thermal throttling.

Build Quality And Connectors

The black casing uses professional-grade cells produced to OEM tolerances since 2006 and carries a one-year manufacturer warranty. Buyers must verify the original battery part number and output voltage before purchase because this pack does not fit every laptop variant even within the listed series.
