In Lenovo laptops, "Battery 1" usually refers to the internal, non-removable battery located inside the laptop, while "Battery 2" refers to an external, removable battery that can be attached or detached by the user. Some Lenovo models have a dual-battery system (called Power Bridge), allowing the laptop to use both batteries for extended battery life.
