Well i have been stumped on this for a while now, and it just keeps getting worst.

At first my car would not start only when it was cold. the battery would die... So i would slow charge it for the night and it would barly start after school at 3:30. but not i can charge my car and it not even hold a charge that long.. now the confusing part..
this is my second batery to do the same thing... The alternator checks out to be working properly.
so i thought well i have a short.... a but i have no evidence to support this. so i thought well lets check to see if the AM radio is draining the battery... so i did the light test: dark area, turn car on. turn lights on, then with the radio off look ahead, turn the radio on to see if the lights dim of flicker.. if they do then your radio is taking to much power... well i did this and no it is not... even at high volumes...

so then i was thinking you know it really is not normal for a car with a battery almost dead to be able to hit the gas slightly to get the car to almost start hit it again and it fires right up... so i am completely stumped on what the problem car be.. but its making me really mad, and i need to learn how to fix it...

Sorry about the long rant.
Cliff Notes:
car battery continuely dies, changed battery nothing, alternator works fine, radio does not draw excess amount of power.. even charging car all night still won't hold a charge for more than 6 hours...

Thanks for any help

 

Did you have your batt checked before you replaced it when you checked the alt? Maybe a bad batt cable?...sounds like a toughy

 

they just said the batery is fine just not at full charge.. the past few times i brought it in, they said its was at about 85%... but today i was thinking about going down and trying to get them to swap me out a new one on my warrenty.. so i can atleast have a batter that will work for a day...
