Is the system that recharges the battery different than the alternator? Lately I've been struggling with a battery not holding charge over a week of having the car sitting in my garage. I want to make sure I don't have some other problem before writing off the battery and just buying a new one. What steps should I take to make sure everything is okay? My ScanMaster3 displays 13.6-14.2 volts when the car is running so I assume the alternator is doing its job. Car ran fine after the battery was recharged the first time, it restarted when stopped the same day etc. Left it for a week, ran it for about 5 min and turned it off (no driving) left it for another week and the battery was dead again.
