Modern cars have a continuous current draw of about 20-50 milliamps to run the clock, keep the volatile memory refreshed, and miscellaneous leak currents.

Even a good fully charged battery may not crank the engine after over three weeks, and starting the engine with the battery significantly discharged many times will kill the battery in short order.

Whenever a car is stored the battery should either be diconnected/removed and charged monthly, or a battery tender should be connected to the battery during storage.
