Alternators

One of the reasons your Acura may not start is because of a dead battery. However, you shouldn't just go out and replace the battery - it may be fine. If the Acura original alternator isn't working properly, it will not charge the battery. If the car starts when you jump it, test the alternator with a voltmeter. Put the voltmeter on 12 volts and touch the positive cable to the positive battery terminal and the negative to the negative battery terminal. If the engine is running, the car alternator should be putting out a minimum of 13.50 volts. If not, it is not charging properly and needs to be replaced. You could also notice some flickering or dimming of lights or find that electrical systems aren't functioning like they used to. You want to check the OEM alternator and battery throughout the year, but most especially before winter. The colder weather can take a toll on the electrical system, which might leave you stranded.
