Battery Problem

[boulder]

I have been having a problem with my battery constantly dying on me or so it seems. I have tested both the battery and alternator and they are both good. I was wondering if it was possible that the ground just isn't getting a good connection and is acting like the battery is dead?

You didn't mention if you looked at the 80amp fuse. Is it ok , or did it go bad?

[boulder]

Ya, sorry the fuse is good.

testing an alt/ batt at an autoparts store does not mean its still good.. You need more info... How did you test it? Over night it dies? What happens when you crank the car?

well easy way to tell if its dying is to check how many volts you have going thru it or to swap in someone elses battery and see if you have the same problem... little more info on how/when it dies i mean does it do it over night or just randomly whenever.

The battery could die within an hour. When that happens the car just can't even turn over. I just does not have the power.

how old is the battery?

[turboaccordlx]

dmm and do a parasitic load test

[newtuner7]

remember that even though a battery might have 12 volts its ability to retain a charge is diminished over time so even tho you may charge it up and it has 12 volts it may not be able to sustain that under load

If you're not leaving the lights on or the radio with the sound so low you don't realize it's on...I would guess that you have a power drain somewhere. Do as the smart guys in the above posts said. I once worked on pay phones and did that swap stuff in the field to see if a part was the culprit; I was in South Central LA...no time for meter tests. I carried extra parts..no time to guess. Put in a entire phone if I could. Bring the other parts back to test in office. Get a buddy to let you use a battery or other parts as they mentioned and replace whats bad.
