A parasitic drain is an abnormal electrical draw that continues after the vehicle is off and can empty a healthy battery overnight or within days.
Common Sources and Diagnosis
Lights, incorrectly wired accessories, faulty relays, control modules, and damaged wiring are common causes. A technician measures current draw after shutdown and isolates circuits systematically.
In Short
When a healthy battery keeps dying, test for an abnormal draw before buying another battery.
