I've never seen reports of that many failed batteries from Optima - and I used to sell them at Sears.

You should have your charging system checked, honestly. There might be a problem w/ the Voltage regulator or Alternator, or even a bad ground that is charging the batteries higher than it should be... they can't take more than 15V, and they're only rated for 14.6 cVDC without failing.
