you want to use batteries that are all the same size and age because as you draw them down you don't want one in the string to be at a higher voltage as it has to go thru the other batteries, if they were all parallel then it would not matter as much but if it was a string in series then it matters as it can have the same affect as hooking a charger up to the dead battery backwards.
