I use both AA and D size batteries for my old radios. AA for the 3 and 6v, and D size in series to make 9v, as an external source. Usually the D batteries will wear very evenly, almost identically in fact. However not so with the AAs, only sometimes. Usually one battery, typically a middle one will wear much quicker. Why is that? Does size have something to do with it? Thanks for any information.
