Dr. Battery MPL07212P-20 6 Cell 11.1V 4400mAh laptop battery

Replacement 6-Cell Lithium-Ion Battery

This new Dr. Battery MPL07212P-20 replaces the original power source in compatible Gateway laptops. It uses six lithium-ion cells rated at 11.1 V and 4400 mAh to deliver 49 Wh of capacity. The pack fits models such as the 6000, 6500, 8500, M and ML series listed by the supplier. A built-in smart control chip manages charging and protects against short circuit, overheat and overload.

Sustained Discharge and Charge Behaviour

The smart chip regulates current flow to provide steady output during long work sessions rather than only brief bursts. Quicker charging and lower power consumption extend usable runtime between wall charges. Protection circuits cut power if temperature or current exceed safe limits, keeping performance consistent over the full discharge cycle. The one-year warranty reflects the manufacturer's confidence in reliable long-term operation.

Thermal, Noise and Power Characteristics

Lithium-ion chemistry produces no audible noise and minimal vibration during normal use. The protection suite prevents overheating by interrupting current when internal temperatures rise above safe thresholds. Power draw from the adapter follows the chip's managed profile, reducing waste heat while the battery charges. No moving parts mean silent operation in office or mobile environments.
