Some parasitic drain is normal – your battery delivers enough energy to keep things, like your clock, radio presets, and security alarm operational at all times. However, if there’s an electrical problem – such as faulty wiring, poor installation, and defective fuses – parasitic drain can exceed what’s normal and deplete the battery.
