Dr. Battery MPL08217P-05 laptop battery 6 cell 10.8V 4400mAh black

Replacement laptop battery

The Dr. Battery MPL08217P-05 is a new six-cell lithium-ion unit rated at 10.8 volts and 4400 mAh. It serves as a direct replacement for numerous HP and Compaq models including the G50, G60, G70, HDX 16, Pavilion DV4, DV5, DV6 and Presario CQ40, CQ50, CQ60, CQ70 series. Users who need a different voltage, a higher capacity or a battery for a non-listed notebook cannot use this part.

Thermal and power behaviour

The pack delivers its rated 48 Wh through an integrated smart control chip that manages charging current and discharge rate. In normal operation the cell chemistry runs at typical lithium-ion temperatures and the protection circuitry guards against short circuit, overheat and overload without active cooling. The battery is not designed for hot-swap bays, external chargers or systems that demand a different cell count or voltage.

Sustained load characteristics

Under continuous discharge the six-cell arrangement provides steady output until the protection thresholds are reached, at which point the pack shuts down safely rather than overheating. The one-year warranty covers defects in materials and workmanship under standard mobile use. Buyers who require extended runtime beyond 4400 mAh, a different form factor or compatibility with models outside the listed HP and Compaq ranges should select another product.
