Not enough details. Is the battery new?

The alternator should put out about 14 volts. The battery when the engine is off should be above 12 volts. You can check both alternator and battery by putting a voltmeter across the battery terminals...with engine running checks alternator, with engine off checks battery. Digital voltmeters cost $2.99 recently at Harbor Freight online.

Does the car fail to restart immediately?, or is the battery dead only after a couple days sitting?

Are all interior lights off? One dome light left on will kill your battery overnight.

Need more description of the problem.
