My battery on my 1998 Pontiac Sunfire GT keeps dying?

[Victor]

I got a new rebuilt alternator. than i got a new battery and my battery was killed in less than a day. so i returned the battery and got another battery. killed again less than a day. so i brought the alternator back to the shop. and they put a new regulator in. so than i got another battery and it was killed the next day. There is squeeling from my surpatine belt and it looks a little loose. so i think maybe my spring loaded tensioner needs to be replaced. but also when i turn on my A/C it makes a really really bad loud noise. people keep telling me its my alternator and they say that stuff has nothing to do with my battery and alternator. WHAT CAN MY PROBLEM BE? is it really my alternator or could that be making a draw on my alternator therefore cauing it to kill my battery?

I dont know rlly good but principal failures whit batterys are the regulator the alternator and the bands, you can also chek the terminals or the cables of the battery, sometimes the terminals have corrosion and disconect. hope i help you.


also chek leakage power and short circuits

did you try putting a voltmeter on the battery with engine running. You should get a reading a little over 13 volts. did you check to see if you have a short that is draining the battery when the car is turned off. It's somewhat pointless to change alternators and batteries if you are not testing to see what is really wrong
