Dr. Battery MPL07217P-21 6-cell 11.1V 4400mAh laptop battery

Dr. Battery 6-Cell 11.1V Replacement

This new lithium-ion battery replaces the original power pack in compatible Acer Aspire, eMachines and Gateway laptops. It delivers 4400mAh capacity at 11.1V for 49Wh total energy. A built-in smart control chip manages charging and provides short-circuit, overheat and overload protection. The black 6-cell unit is designed to meet OEM specifications for reliable mobile power.

Upgrading from a worn original pack

When the factory battery no longer holds a useful charge, this replacement restores full runtime without changing the laptop. The jump is worth it if the original cell count and voltage match the 6-cell 11.1V specification listed for your model. It is not for users whose laptop requires a different voltage, cell count or physical form factor than the models listed in the compatibility data.

4400mAh capacity for everyday mobility

The 49Wh rating comfortably handles typical office tasks, web browsing and video playback for several hours on a single charge. Runtime scales with screen brightness, CPU load and peripheral use. It runs out faster under heavy multi-core workloads, gaming or when driving external displays. The pack is not for users who need extended off-grid sessions beyond what a standard 6-cell design can supply.
