Remove any cables plugged into your vehicle, such as a GPS unit or phone charger, and charge the battery to 100% before plugging it in using a vehicle battery charger.
If your battery isn’t reading 12.6 volts when fully charged, you should replace it. Remove the negative battery cable with a 10-mm open-ended wrench. Check the fuses in the fuse box(es) under the dash. If you don’t have a friend to help you, prop the meter against the windshield to read it.
If you can use the radio with the ignition in the off position, you have a problem. A 2004 Saab, for example, has a fuse box in the engine compartment. A badly-worn ignition key can cause a battery drain, for example, if the key can be removed without turning it to the lock position.

What is an acceptable parasitic draw on a battery?

A normal amount of parasitic draw for newer cars is between 50-milliamp and 85-milliamp current draw, while a normal amount of parasitic draw for older cars is less than 50-milliamp current draw. Anything above these amounts indicates an electrical problem that should be addressed by a mechanic.

How many amps is considered a parasitic draw?

A parasitic draw test requires a Digital Multi-Meter (DMM) that can handle a minimum of one milliamp and up to 10 amps.

Can a bad battery cause a parasitic draw?

However, a parasitic draw can be caused by a bad alternator diode or even a faulty battery, and depending on the amount of current drained, a parasitic draw can drain all of your battery’s juice in a matter of hours or minutes.

Can an alternator cause a parasitic draw?

A bad diode in the alternator can cause a parasitic drain on the battery, allowing the battery to go dead overnight. Diodes should only allow current to flow in one direction, but a bad diode will keep the charging circuit open even when the engine is not running, allowing the battery to go dead.

Can a bad ground cause a battery drain?

Your vehicle’s charging system relies on a good ground; if the ground wire is damaged, the battery will not be charged. Of course, problems with your alternator or the wire that connects the alternator to the battery could also be the cause of a dead battery.

What is a parasitic drain on a battery?

Why would you run a parasitic draw test?

This is known as parasitic draw, and it occurs when a short circuit occurs that is difficult to pin down. A certain amount of draw is normal u2013 in the region of 25mA (milliamps) u2013 but if you are losing 100mA or more, something is wrong.
