Agree with Larry as far as the sensible thing goes. DXont leave radio, lights ect on while engine is off. Take care of your battery.
Kinda disagree with battery becoming a no-issue at least economically for a USED car battery. If the original person who started this thread buys a Prius and has to buy a new battery then his sweet deal might become a financial nightmare depending on the cost of new batteries. Remember that we are not talking about $75 auto batteries that you can get at Costoc for even less.
Lastly, people seem to forget the main reason why Priuses, Insights and Honda Fits get such good gas mileage: Its the size of the small 1.2-1.6 L engines that they usually come with. Corollas (NON-hybrid) overseas can get over 60mpg because they come with smaller engines. (same car, smaller engine). Most hybrids come with a small European sized engine mated with an electric engine to boost it up to "American-sized" horsepower and acceleration. Im willing ot bet that you dont NEED the Prius' electric motor and can do fine with just the gas engine itself. Back in the days it was very typical to have cars with under 100hp, even 80hp on economy cars, that got reasonable gas mileage. With all of todays technological advances, we could get double the mpg but have instead focused on getting double the horsepower. Not that the 1st Altima has about 120-130 hp whereas todays Altima has 175hp base and 270 for the 6cyl version which is FORCED on you if you want certain features and upgrades.
With all that said I wouldnt worry too much about the battery in a hybrid unless it REALLY needed batteries juts to even drive. A hybrid running on motor alone should get good mileage, at least, I think
