I don't know how I missed this thread before, but I have a track record of testing batteries in Arizona. You must be prepared to leave the car for testing for 7-9 months starting in April. A very low 10 bar or 9 bar car should be the best candidate. The car testing will be over normal road conditions in the Phoenix Metro Area. Cheers!
