What is a parasitic draw?

In some cases, you might experience what is known as a parasitic draw, also known as parasitic battery drain, which is when a continuous and abnormal discharge of power occurs, even after the engine is shut off. Walking out to your car ready to start it only to be greeted with a clicking noise can be frustrating.

What causes a parasitic draw?

Parasitic Draws

The problem occurs when your electrical system isn't functioning properly. Issues such as faulty wiring, bad fuses or interior lights that fail to shut off will continue to drain your battery while it's idle.

How do you stop parasitic draw?

How do you know if you have a parasitic draw?

If your vehicle is drawing power from the battery and all of the lights and other electrical components are off, you might have a parasitic battery drain (or draw).

How many amps is considered a parasitic draw?

“Typically, the normal amount of parasitic draw is between 50 and 85 milliamps in newer cars and less than 50 milliamps for older cars.” A parasitic draw above this threshold is considered excessive. Over time, excessive drain can stress your battery, drawing it down quicker and shortening its life.

How To Perform a Parasitic Draw Test - EricTheCarGuy

Will a parasitic drain ruin a battery?

What's the Danger of Parasitic Drain? 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.

What is draining my car battery when its off?

What may drain a car battery when it's off are things such as interior lights, door lights, or even bad relays.

Can a blown fuse cause a parasitic drain?

No a burnt fuse can't cause battery drain issues. Some fuses don't get power until the circuit is turned on so don't be concerned about them.

How do you find the source of a parasitic drain?

Some check parasitic drain directly at the battery with a digital ammeter and a test switch. Others do it by clipping an inductive current clamp around a battery cable. If the drain is excessive, the most common way of isolating the cause is removing one fuse at a time.

Why does my car battery keep dying overnight?

This happens when something – a glovebox light, an amplifier, any electrical component – is pulling power from the battery when it shouldn't. Since the alternator isn't generating vehicle electricity, the problem component pulls from the battery, slowly draining it overnight until your vehicle won't start.
