The at least one cell has a nominal capacity of at least 1.5 ampere hours, as well as a surface area A and a volume V. The surface area A of the at least one cell is greater than eight times the cube root of the square of the volume V of the at least one cell. In addition, a ratio of resistance and surface area of the at least one cell is less than 0.2 millionm/cm. A power tool having a energy supply device is also provided.",
