The boxplot shows that the median (middle value) is closer to the lower end of the box, and the right end of the box is shorter than the left end. Additionally, there are several outliers on the right side of the plot, indicating that there were some batteries that lasted much longer than the rest. This is characteristic of a right-skewed distribution.
