1996 Chevy Blazer battery draining/won't start

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?

    I have exactly the same problem. Its not the battery (have replaced it), it's not the alternator (have tested it), and can't find any shorts. We can charge the battery and the car works fine for a couple of days. Then all of a sudden one night the battery drains flat. We also have a 96 blazer (same year).

    OK everyone....we found the problem..,yeah! It was a stuck Lumbar switch on the passenger side. Must be one of the kids kicked it getting in our out of the blazer and it was constantly running. We unwired the switch and it works fine now. Something so simple. We discovered it because of the humming noise we heard when sitting in it with nothing running.

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..

Thanks,
Steve

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"

2007 Vue hybrid. 12-volt battery dead? No electric key opening, lights, starting, etc. Can I try to trickle charge it? We;ve been away a week, but it has been sitting in a garage above 50 degrees.


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!

When we turn key car is dead. Car has been sitting for 2 months.


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.

My battery keeps dying but my alternator is fine


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.
