Update: I installed this switch, a 20A Digi-Key #CW100-ND, and repeated measurement of the battery drain. Chevy cobalt 2010 die after fews days install#I'll either continue doing this, replacing the fuse with a new one periodically, use a battery charger, or, as another writer has suggested, install a switch in series with the fuse, which, if there's room, would be the best option. I used the 30A Memory fuse regularly for a while, but started having reservations because the contact grooves in it were getting deeper with use and I was afraid it would fail (open circuit) causing the engine to cut out (can anyone confirm or refute this?) at a critical time. I don't drive the car often enough to keep the battery voltage up. Chevy cobalt 2010 die after fews days full#It's worse now that the battery's 8 years old and no longer takes a full charge. ![]() Not excessive, but I found that even this was problematic if the car was parked for more than a week. With my 2009 Genesis, which is loaded with electronics, the ammeter readings after about two minutes alternated between 27mA and 16mA as the dash security light turned on and off. I suspect Phil B got a high (470mA) reading for the battery drain in his 2012 Sonata because some or all of the car's electronics were still active because not everything was shut down, including locking of the doors and closing of the hood and trunk lid. Then my friend led the dealer a bit and asked if there would be any kind of fuse that could be pulled to reduce the current draw. He got only a blank stare from the dealer and no answer. ![]() Then my friend asked what he should do if he needs to leave his car at an airport lot for a few weeks. When my friend asked what to do, the dealer advised buying a trickle charger. The dealer said new cars of all makes and models have so many electronics items running in the background, even when everything is "off," that the battery on newer cars will go down fairly quickly. He asked about the battery going down in a short time. He did not let the dealer know he is aware of the memory fuse. UPDATE: October 9, 2012- A friend who owns a 2013 Sonata spoke with his dealer in a different state and city. A dead battery after a few days has been a problem on several makes of car, not just my 2012 Hyundai Sonata. Some have had the dead battery problem because of a bad cell in the battery, faulty battery cables, a bad diode in the alternator, or even a problem in the car's radio. But, the search for a solution to my problem can be more complex and confusing than it would seem. From doing searches on the Internet, particularly on an owner's forum, I suspect this information has escaped others, too. Even if I had read this, I am not sure I would have remembered it or that I would have made the connection in my mind. It describes a memory fuse that can be pulled when leaving the car unattended for long periods of time in order to avoid a dead battery. Chevy cobalt 2010 die after fews days manual#The graphic is a page from my owner's manual in the section on fuses. Yes, I should have read the entire manual after I bought the car, but it is hundreds of pages long. The dealership might have told me there is information in my owner's manual that advises me to pull a special fixture on the fuses, and that would reduce the current draw to a very low level. My question of the dealership was, "What do I do if I need to leave the car in an airport parking garage for a couple of weeks?" There are no electrical outlets in the parking stalls at any airport garage I know. I could mount it in the engine compartment and connect an extension cord to it when we will be gone for more than a week. This is a battery conditioner we bought a few years ago for another purpose. If I am concerned, I should connect a trickle charger when I will leave the car unattended for more than a week. At a recent visit to the nearest dealership for routine warranty service I asked about this. With everything "off," the doors closed for a few minutes so all dome lights have gone "off," and the key removed there is a current draw of 470 milliamps, or nearly half of an amp. The leads plug into the meter at different terminals for a current reading than they do for a voltage or a resistance reading. Check the terminals on your meter to be certain you have the leads connected properly for the scale on the dial. I was reading the manual for another new vehicle and it seems some things need to be reset if the battery is ever disconnected.) The meter was set to measure DC amperes. ![]() (Check to be certain it is safe to do this on your car. I disconnected the negative (-) battery cable and connected my multi-meter between the cable and the battery post. ![]()
