Voltage and capacity

This replacement laptop battery delivers 7.4V and 6100mAh for 45Wh of energy storage. It uses Li-ion cells and matches the L12M4P61 part number used in Lenovo IdeaPad U330 Touch U330P and U330T series machines. The pack is black and built to the same physical size as the original battery.

Compatibility focus

The unit suits owners of the listed IdeaPad models who need a direct swap for a worn or failed L12L4P61 or 21CP6/69/71-2 battery. It will not fit other Lenovo lines or any non-Lenovo notebook, so buyers with different part numbers should look elsewhere.

7.4V 6100mAh rating

The single figure that decides fit is the 7.4V 6100mAh (45Wh) rating printed on your original battery label. If your old pack shows a different voltage or capacity this KingSener model will not work correctly.
