From what I have read in consumer testing magazines & facilities where batteries were tested(D, C, AAA, AA, 9v), it isn't the brand that was most important but, the type of battery. e.g.,
an Alkaline is an Alkaline, a heavy duty is a heavy duty, a standard cheap regular duty battery is a cheap regular duty battery. There were only insignificant differences between brands which could change in different batches, it was said.
