I have a fairly new battery, but something is draining the battery over nite
My battery is only a few months old but would not hold a charge. I have recharged it several times, but something is draining the battery every nite. I charge it and it cranks and runs fine, but when it sits over nite the battery is dead. Some one told me it could be a modual, or something. I really can't afford to spend any more money on it.
I will aprreciate some help.
Thanks

L'm sure its your alternator ! he did not give the correct voltage and not charge appropriately your new batterie , just check it and you will see ! :)

Make sure the battery is good. U can charge it and disconnect it from car overnight and see if it works the next day. If it is still fine then the car has a drain. If no good, then the battery is bogus and cannot hold a charge.
U have something in wiring that is draining the battery after shutdown. Need an ammeter. Hook it up to the battery and wait about a half hour. Then notice draw on meter. Start removing fuses until you locate the line that is responsible for the draw. Then check out each and every item on that trunk line.
If the alternator is good and the battery is new, then something is draining the battery while it's parked. In the old days people left their headlights, radio or something on and this drained the battery. Now a days this is not as big a problem with 5 minute timers that turn off lights if you forget. I would take it back to whomever did the alternator work for an answer. How old is the battery? You can take it to see if it can't hold a charge any longer. In my experience, most batteries don't seem to hold a charge after about two years. Did anyone do some custom work in your car that requires electricity? It could be this extra stuff is draining the battery.
I think you should go for manual first after that it would be easy for you to solve your problem. I had visited this site past 2 months before for my vehicle and find it quite helpful may be you will also get something useful here Hyundai
It wouldn't be the starter. It will not draw current when not engaged. Could be a light left on, a trunk light, glove box light, under hood light-an unintended drain, somewhere. Sometimes a penny or something gets stuck in cigar lighter and keeps that circuit on. You should check if alternator is fully charging up the battery after it has run, and then turned off. But if you don't have a voltmeter handy, try this: When you shut if off to sit overnight, take the negative battery terminal off the battery. When you get ready to start it, hook up the battery and see if battery is no longer weak. If battery is now good, you do have an unintended drain. If battery is weak again, check charging system, battery cables and connections, alternator connections-a loose connection will prevent battery from charging. If you have a drain, turn everything off and remove key. Pull the bulb out for the underhood light. Take negative off battery again, and hook up a testlight between the negative battery cable terminal and the negative battery post. If something is pulling current, the testlight should be bright. Now at fuse panel under dash, pull fuses one at a time and watch the testlight. If you pull a fuse and the testlight goes off, that circuit has the unintended drain. Check everything on that circuit. Hope you find the problem. Good luck.
Hi
A car battery can run down for any of several reasons:
You accidentally left the lights on or some other accessory that pulls power from the battery even when the ignition key is off.
The battery is not being recharged while the vehicle is being driven (you have a charging problem)
There is a key off parasitic electrical drain on the battery because a relay is sticking, a module is not shutting down, or there is a shorted diode in the alternator.
Your battery is old and will not hold a charge anymore. The battery needs to be replaced.
Most of the time if the battery is fairly new and keeps getting drained have the mechanic check the alternator if its charing the battery.
Thanks for using Fixya.
Small drain on battery from radio, clock etc, will draw it down over that much time, so even a small charger, or short drive once in a while, (little more often) will keep it up if all is working on charging system. Check brake fluid level, as well as try pushing emergency brake handle down, to see if maybe that just sticking. be careful not to pull it too far as it may be partially seized from sitting too much. Let me know what you find.
The battery is more than likely completely drained. Because those vehicles have so many electronic features, both mechanically and otherwise, they consume a lot of juice. If the car is going to be sitting for more than a month you are supposed to remove the long term storage fuse. It is located under the hood. Your owners manual will show you a picture of where it is. I would take the battery out, remove negative first then positive and have the battery tested. If the battery is completely drained it will not hold a charge either with the alternator or with cables. Just make sure you install the battery cables in the reverse order, Positive first then negative.
