Hidden Culprits: Why Your Car Battery Is Draining Overnight
A mysteriously depleted car battery, especially when it's discharging power overnight, can be incredibly frustrating. While normal degradation eventually takes its toll on any battery, a rapid drain suggests a hidden cause. Often, it’s not just the battery itself that’s to credit; several minor electrical loads can slowly siphon power. These might include added accessories like audio equipment, alarm units, or even incorrectly installed lighting. A defective door sensor, a stuck relay, or a parasitic loss through the wiring harness are also likely culprits. Finally, a failing alternator might not be fully topping off the battery, compounding the situation and leaving it open to overnight discharge.
