Can a parasitic drain kill a battery?
If a battery goes long periods without being recharged by the alternator, those tiny milliamps drawn by parasitic devices will kill it. Even normal parasitic drain, also known as “key-off drain,” puts wear and tear on a battery. Allowing a battery to go dead for long periods of time will cause sulfation.
Can a bad alternator cause a parasitic draw?
A malfunctioning diode in the alternator can create a parasitic drain on a car’s battery.

Can a bad fuse cause battery drain?
The fuse in and of itself cannot be the cause of the power drain. It is, however, an indication of where the power drain is coming from. If by pulling the fuse you get a noticeable drop in battery drain, whatever is causing the drain is on that circuit.
