Zero Power RAMs: date codes and how long are they good for?

I want to get some Zero Power RAMs for my Race Drivin'.

1) Are there date codes on them? Do they matter or will a 10-year old unused one last as long as a brand new one that has not been used yet?
2) If my game is mostly off, how long can I expect the battery to last? 1 year? 5 years? I will not keep the game turned on just to save the batteries.

Thanks!
