Would a car battery die from listening to the radio?
Okay, I was driving my car about maybe 6 blocks, then I stopped and shut the car off but kept the radio on for maybe 30 min and then shut everything off. After that I started the car back up again and the battery light came on the dashboard. The battery is only a year old and I don't see how a simple radio could make it die, can someone please explain?
Car radio stopped working after dead battery?
sooo i have a 1998 bug and im pretty sure its not the original radio, but one morning i had to jumpstart my car because the battery died, and on the way to school afterwards i kept all my electronics and stuff off because my stepdad told me to. so ever since then, my radio doesn't work. it has a casette player and cd changer, and so when i turn the radio on, the screen that says what the radio station is turns on, but there's no sound. i tried pressing all the other buttons and that screen doesn't change, the only thing that works is the eject for the cassette. so it'll turn on, but there's no sound. also, i have the ac adapter thing in my car, and before when my radio worked, the ac adapter didnt, but now it does. so maybe the power got switched between the two? my stepdad is a car guy and he looked at it, but he just said he didn't know what to do either. any help? i have no idea about cars though, so keep that in mind.
Should a car battery be removed if it's going to be parked for a month or more?
Oh boy… you’re going to get all sorts of answers on this one.On a 2009 Lexus that is going to be parked for a month, I would not even consider removing the battery. There is no compelling reason to do so and the pain and aggravation of removing and re-installing is just not worth the potential problems associated with it.It is not uncommon for a vehicle to sit on a show-room floor or an auto-parts shelf for 30 days, right?If you’re worried about the battery discharging while you’re gone (which is unlikely), a much, much better idea would be to connect a trickle-charger… but if the battery is in good condition, you won’t even need that.Removing and reinstalling a battery is not difficult but there is a procedure for doing it correctly and you risk damaging the electrical system if it’s not done correctly (particularly on re-installation), not to mention the hazards associated with handling an acid-filled, 25 pound lead-heavy component.If the battery is removed…You will lose all (or most) data stored in memory (and on luxury cars, that is considerable). It’s not just the radio settings, there is GPS info, seat-position settings etc., etc.In some cases, the computer will have to re-learn certain protocols.You won’t have an alarmIt can’t be moved in an emergency.On some vehicles (particularly BMWs) you might not even be able to get back in the vehicle with just the key.The worst that’s going to happen is you’ll need a jump-start when you get back.If you do remove it, I can practically guarantee you’ll have a check-engine light when you re-install. Don’t you wish I was your mechanic?
The Battery keeps dying in my cousin 89' Crown Vic?
His battery keeps dying. He bought an new Alternator and that's not it he keeps buying and charging his battery. He checked his fuse and its not his fuse. Help me and my cousin out I'm tired of taking him to work.
Can a short in my car radio cause my battery to die?
The radio or anything else electrical could drain the battery overnight if there is a short. But it could not do it immediately. If there were that much of a short, there would be a fire. The way to test is to remove the battery cable with everything turned off and insert a test light. On-board electronics will consume a small amount but not enough to light a bulb. If the bulb lights, you have a short. You copuld then further isolate it by selectively removing fuses.
Car battery keeps dying overnight?
Sorry Pete, I don't mean to contradict you but that's not how you check for a parasitic draw. You don't use the multimeter on DC volts. Most radio memory and other memory functions for say automatic seats and mirrors draw between 9 and 12 volts normally, so you are going to register high voltage on the meter if you us DC volts function and that is normal. For a parasitic draw test, you turn everything off that can be turned off and make sure the doors are closed. turn your multimeter on and set it to DC amps. disconnect the negative battery cable and hook the black probe of the meter to the negative cable and the red probe to the battery negative post. the reading on the meter should be no more than .5 amps (500 mili amps). if you have more than .5 amps than you have a parasitic draw somewhere. now you can start pulling fuses one by one (do not put them back in until you find the one that is drawing the extra current) once you find the problem circuit, leave this fuse out. now you can start replacing all the other fuses one by one. check the meter as you replace the fuses to make sure the draw doesn't come back. some systems have more than one fuse protecting them, so don't be surprised if the draw comes back when you replace one of the other fuses. If it does, leave that fuse out as well. now you have narrowed the problem down to just a few circuits (depends on how many fuses had to be left out and what systems they protect.) now you need to check the wires and other components in those circuits for damage or other problems. (sorry, cant be specific without knowing what systems are affected.) Good luck, I hope this helps.
Can a bad car battery cause engine misfire?
So everyone on hear that says a weak battery cannot cause a misfire is wrong especially with a Subaru!!! I recently ran into this exact same problem with my 2013 Subaru Impreza 2.0L. My car began to have a rough idle anytime I was sitting at a stop light. Then the CEL came on for a misfire in the cylinder and the dealership wanted me to do $1000 worth of work replacing the coil packs and spark plugs. I specifically asked them if a weak battery would cause the problem and they said no as well. I knew my battery was weak because I couldn't leave my car radio on for 5 min with out the battery dying. All battery tests I did said the battery was fine. Today I finally got sick of having to worry about it not starting from leaving the door open or the radio on while it wasn't running. Sure enough my check engine light turned off and now my car has greatly improved performance! Also my car now idles like it is supposed to. I'm thinking my fuel pump was not getting enough power which caused the misfiring. Either way the problem is fixed and I suggest looking into the battery first!
How long can I run my car's stereo system before I drain the battery? Assume the typical battery in a typical new mid-sized sedan on auxiliary power.
Surprising, not very long. Most newer vehicles come with undersized batteries, just enough for a few starts in the worst of conditions.Your car radio doesn’t require much power assuming you are not trying to piss off your neighbors, however it does require constant power when on, so while your starter is a huge draw on the battery, it only draws for ~3 second then the alternator immediately starts to recharge the battery, your radio sucks the power without the benefit of the alternator replenishing the spent power while the car is off…in short, I would think if your vehicle in newer, with a factory battery, all in good condition, and you are listening at a reasonable volume (not trying to impress the rest of the world with your factory base) you are likely safe for an hour IF all othe accessories are turned off.Ok, so you forgot your radio on and you come back to your vehicle and suspect you ran down your battery, what do you do now. Shut the radio off, and let the battery rest as long as possible before trying to start it. A half hour minimum an hour is better. If it starts, after the resting period your not done… leave all the accessories off and running your engine for 5 minutes at a driving rpm (~2000–2500 if you have a tach), then take it on the best nearby highway for at least a 15 minute drive if you can leave off all accessories, 30 minutes if you require headlights or blower, even longer if you can’t get up to at least 40 mph without constantly using the brakes (brake lights use a surprising amount of power if not LED) … Assuming your battery was in good health before you drained it, then this charge cycle should be enoungh, otherwise, you might need to replace your tired, undersized, battery with a new one… should you have to replace it, it is always better to purchase a more powerful battery than what came with your vehicle, but that is an answer for another question…
