I'm not sure how well this re-flash woks. In the almost three years I have had my 05 the only time the battery was dead was when it had a bad cell a few months ago. It would sit for almost a month and would only drop to about 11.9 volts. Since getting the re-flash the battery will not hold up a week without charging. I let it sit for less than two weeks and it would not start (measured 10.5 vdc). It could also be the apparent POS Optima red top that I put in.
