does product # include date made
I bought a pack of AAMax20 and none of them work. How can I tell if I was sold a pack that is old with out an expiration date. Is it encoded in the proof of purchase bar code # which is 39800- 10359? The only date I see is © 2010- is this when they were made ? My battery checker says they are no good.
