Yes. More so if it is connected. Most vehicles today put a parasitic draw on the battery that will drain it down over time. Parasitic draw should be under .050 mA.
battery no longer can store a electrical charge, a charging system failure, a parasitic draw,
Check for a key off draw (or parasitic draw) Should be less than .5 Amps
The correct spelling is "parasitic."
Parasitic draw is in reference to electrical loss as Parasitic loss is in reference to horsepower loss through accessories that run off the drive belt that comes off the 'crank' of the engine such as the water pump, cooling fan, a/c compressor, power steering pump, super charger etc.. Parasitic loss in electrical is refered to a loss of electrical power when the vehicle engine is not running and the ignition is off. this could be a door ajar causing the interior light to remain on causing a electrical draw(parasitic loss) of the battery. Eventually causing the battery to die. Most causes of electrical loss are not this simple and require at times hours to track down. Fastest way I know is to unplug your vehicle harness in sections while having a meter monitoring the battery amps. Depending on the vehicle, a vehicle may have up to .050 amps of parasitic draw from items such as clock and radio memories, any more than that and you will have battery prolems if the vehicle is not run for several days.
Parasitic draw on most vehicles should not exceed 50 milliamps (0.05 amps). A luxury vehicle with lots of accessories may draw as much as 80 milliamps (0.08 amps).
No, sponges are not parasitic.
I like to see .050 ma or less but some high end vehicles draw as much as .080 ma.
The charging system may be faulty or you may have a parasitic draw. Its also possible that you have a loose connection, or you have an electrical and/or computer problem.
Depending on the amperage rating, you could blow an internal fuse.
