Am I cutting the life of both
Am I cutting the life of both my batteries by not driving much? I kept changing my 12 volt and the mechanic said to drive more, and I think that helped. But for the past 2 years I have stored my car with the 12 volt unconnected for 4 months while out of town. But now this 2008 Prius needs a new hybrid battery at only 50,000 miles. One person told me that the age of the hybrid battery is more important than the miles. True?? (I live in a remote town without hybrid specialists.) Thanks!
