Dr. Battery MPL10227P-25 6-cell 4400mAh 10.8V laptop battery

Drop-in replacement for Lenovo Essential

This 6-cell lithium-ion pack replaces original Lenovo part numbers including 121000935, 121000938, 121000939, 121001056 and 121001096. It fits Essential B470, B570, B575e, G460, G560, G570, G780, V470 and V570 models as well as IdeaPad Z370, Z560, Z565, Z570, Z570A and Z575 systems. The 10.8V output matches the voltage required by these notebooks.

Installs without tools and restores full mobility

The battery slides into the standard compartment on the supported chassis, requiring no adapter, cable or firmware update. Its integrated smart control chip manages charging current and provides short-circuit, overheat and overload protection during operation. The 4400mAh capacity delivers up to 48Wh of energy, freeing the user from a wall outlet for everyday workloads.

Steady output during extended sessions

Under sustained load the pack maintains a stable 11.1V device voltage while the protection circuitry prevents thermal throttling or sudden shutdown. The lithium-ion cells are rated for consistent discharge across the full cycle rather than brief bursts. Buyers needing higher capacity for all-day runtime or a second pack for hot-swap scenarios should look elsewhere.
