We can put the battery charger on it and it will start & run fine then we leave it overnight and the battery is dead the next day. We replaced the battery so we know that's not it. Can anyone suggest what might be draining the battery dead?
What normally you have to look for is that your belt is running properly because your car might be running a lot more off the battery and not so much of f the alternator, but normally if the alternators bad it will drain the battery even if the cars not running.. Yes your first thing you would want to do is check the wiring and al that just because thats cheap and easy but most likley you wanna get the altenator tested...you can get that done at advance auto.. please rate me if you get a chance and if you have any other questions just let me know ill check up on your problem..
Hello it sound like you have some thing draining your battery. there is something drawing power from your battery. it could be a wire that is shorting out some where under the dash. maybe from where some one hooked up a stereo and there are bear wire . grounding out.!! could be a short under the hood . from some one hooking up fog light's or running or a spot light.? check these place's i talked about and see if you can find anything . and let me know. ok "GOOD LUCK"

something draining the battery .check blower motor sometimes keeps running even when indicating it is off .remove battery terminal and tap against the terminal to see if there any large sparks.if they are . remove fuses one by one as u test till the spark is not there .find out what links are used on that link and disconect one by one when the fuse is on and test if the large spark is still there
If the battery is completely dead a trickle charge won't do much. These are designed to keep a good battery good. You need a regular battery charger set to 10 amps for a couple hours then 2 amps overnight. Be aware that sometimes if your battery has been completely killed it may not work for long, that is your car will start but within a few days or hours it will leave you stranded. You'll know because it will drag when you try to start it. Sometimes you get lucky and it works great for years.
Next time do use a trickle charger! Also if the charge you use is automatic then you can leave it hooked up in 2 amp mode when you are gone. Good luck!
you need a mech you have a draw whitch meeans something is on at all times or internal short on something or pass bad batt.
make sure things ore off like dome light trunk light cig lighter out of socket cell phone charger etc. good luck
replace your battery, a battery discharges every day you dont run the alt. to charge it up... after a week or 2 weeks the battery would be dead, just from a car sitting not being started... if you are not using the vehicle, it is a good thing to replace the battery, and every couple days just start the car up and let it run a while to charge the battery.... if you are going to have to leave the car for a while without starting it, then disconnect the battery, and remove it from the vehicle... you can buy a cheap trickel charger for the battery when it is out that will keep it charged till you decide to put it back in.... hope this helps you...
Take the SUV to an autoparts store that features free charging diagnostic tests. They will determine if the alternator is putting out sufficient power to recharge your battery. There's also a very good chance your battery is dead. It's not uncommon for a battery to need replacing (especially in a truck with all the bells and whistles I'm sure the Santa Fe has) after 4-5 years. It's also important to ensure there's no corrosion around the battery posts/cables (will have a white or green powdery appearance). Corrosion would prevent the battery from accepting a full charge.
I hope this clarifies your problem. It's unlikely the alarm system is the culprit provided it's not "going off" all day long. Best of luck and please feel free to post back with any other questions.
First, DON"T check your alternator that way anymore. It's not good to do on newer systems! The best, quickest check I can tell you is to put a volt meter across the battery. Running with accessories off you should see voltage of about 13.5 to 14.5. With all accessories and headlamps on high turned on, it should not drop below 12.5. (and that is the absolute low end!). It sounds like something in the car is staying on. check the glovebox light and interior light delay and make sure they are OK. Otherwise, you will have to start checking entire system for a draw that's taking out the battery overnight. To check, you can pull one fuse at a time and see if draw goes away, then check system that fuse serves.
