Battery drains everyday. Battery itself is good and so is the altenator. Still drains have to jump it off with a booster or another car. Never had any problems like this before. Had the car 3 years.

it can be a number of problems one can be you have something is staying on it can be a light in the boot,you alarm is wired wrong or a radio is not off or it can be the battery no good. By jumping the car with a jumper leads can damage the battery, or you alternator is not charging good. First to check your alternator you will need a volt meter and place the negative from your meter to the negative of the batter and the positive to the positive and start your car. If the reading is 14.3 V to 14.8 V your alternator is good than the problem it can be any of the other things that I indicated
if car needs jumped everyday. then you may have a dying battery or the alternator went south. with car running, nothing on. should produce about 13.6-14.2 volts at battery if alternator is good.. with car off at battery, it should read at least 12.5-13 volts. good-day !
in order for the car to do conventional jump, you'll need to leave the booster cables hooked up for say, 10 minutes at least. you may have left lights on accidently.while the other car is attempting to boost yours,look for anything you may have left on,headlights,an interior light on,maybe a door left cracked open.the cold weather wreaks havoc on car batteries. your battery may need replaced. autozone, advance auto parts, both of these parts places replace car and truck batteries free.they also can check your battery to see if does need replacement.they can also tell you whether you may have an altenator thats bad, your car dieing issue may be your altenator bad,when your altenator goes bad,the car will run until the battery is drained completely. if that is the case,you can take your battery out, have it charged,then drive to a close repair shop for altenator replacement.hope this helps,and as always,thank you for choosing fixya.com
If you have to jump the battery, then either the altenator or voltage regulator (built in altenator) is bad. Most part stores will test it for free. Even in the vehicle. Either the altenator/regulator is bad, or there is a short draining the battery. The is a seperate issue. Could be bad abs pump or circuit which will have to be diagnosed with a code scanner or engine diagnostic machine just for abs systems.
When using a booster of the type you are make sure you have a good clean and tight connectio where you are hooking it to the battery. If you do not have a good connetion the jump will not work , because no current is going from booster to your car. If your battery is too dead a jump will not work either the battery would have to be pulled charged and checked. The battery may have to be replaced. If this is the original battery and the car is a 2005 the battery is about due for replacement.
well if the altenator is charging it will run after getting a jump, you replied you put a battery charger on it but that dont mean the cold cranking amps are good or it could have a dead cell. I would have the battery tested for sure. If you didnt drive far after jump the altenator may be bad but having the battery charged and still does it tells me it is least likely. If the battery tests good the cables could be corroded under the sheath where you cant see. There are other reasons but from what you have posted sounds like you need a battery most auto stores test them for free (load test also)
Sounds like the alternator may be missing an excitation current source.
Check the 'IGN' dash indicator lights when you turn ignition switch on prior to starting motor,
if not one of the below may be problem:-
1) check exiter control wire is connected to alternator D+ terminal (low current wire, +V with Ign on),
2) replace dash 'IGN' indicator lamp.
It's a small draw if it takes that long, I would start by checking the under hood lamp, they have a mercury switch which if it is not on level ground have tendency to stay on, the switches also plain and simple fail and keep the light on. Same holds true if it has a trunk lamp, and the third is the glove box lamp. The best was to check these of course is in the dark. Typically you would remove one of the battery cables use an Ammeter in line and this would give you an amp reading if there is a draw an how much, once you have this, you can pull fuses until the draw stops. which ever fuse or disconnected item will now be exposed.
