OK so i bought a new battery about a few months ago because my original one was done. I bought a optima red top, and i know about the mixed opinions about optima batteries so spare me this one ha. We ends up i had it for about a month and my car kept dying and my starter began acting up so i took it back and they replaced it after the second time i came in with a dead car after i had clearly driven it 10 miles to the part store and they didnt want to replace it, but they finally did. Well now i am in the same predicament. The battery seems to die if i dont drive it for a week or so. How can i test to see if something is drawing some voltage when the car is turned off. Any other things it could be. Im getting pretty fed up with optima if i go in again and they say its another bad battery...???
