    Answer: Yes, we can use ANOVA to analyze this data.

    Explanation: Using ANOVA to analyze the data is allowed because there are more than three groups of batteries that are being compared. The data we are looking for is also quantitative data because there will be a specific measurement of data received. ANOVA is the model used for analysis of variance. This model is used to receive exact statistics of different observations.
