Battery Drain

[SHOMADMAX]

If i leave my car set for more than a day and a half strait without running it, the battery dies. I checked the battery, its good, its not a ground problem, its not the thing in the trunk, and it is not the alternator. What could it be?

Use an amp meter with the car shut off and look for a excessive draw of current, if found you can start pulling fuses till you locate the circuit that is doing the drawing.

FWIW, I had a brand new battery and altenator, and could still **** the battery very quickly.

Replacing my battery cables made the world of difference...the battery now gets all the charge it needs...

load test the battery..

im not sure if autozone can do that or not....

the battery may "looked charged" as in read 12.6V's, but have not cappacity left.

you have some parasitic draw of some kind...

I did that already and it checks good for that and good charge.

With everything off and the key out of the ignition there should be 0.050A draw or less. Anymore and there is a problem.

There will be a current spike right when you connect them though
