get your battery tested for free at an autoparts store. if its not that then you can have a bad ground or something

first have battery tested, second have charging system tested and third check for a parasitic drain by hooking a ammeter in series with neg battery terminal, spec is 25-50 milliamp drain at rest with all doors shut and under hood light unplugged

Its not my batt, did a test on it and its fine. My charging system seems to be fine also it shows over 13 volts when driving. Its gotta be draining out. My car sat at work today for 8 hours and it droped down to about 10 volts and i had to jump it again....what is the easiest way to try and trace where all my juice is draining to?

we already told you how.... so read the thread again

also, try disconnecting a battery terminal for the day, then try to start it afterwards

don't you read!!!!!!!!!!! look at number 3 on my tests!!! you know what that is???, you'll need a DVOM set it to amps and hook it in series, once you determine there is a drain above the spec of 25 to 50 milliamps then pull fuses until drain goes away then reference that circuit to a diagram and then unplug components on that circuit until drain is gone, if after pulling a fuse one by one and none remove the drain undo charge wire to alt and if then drain goes = bad alt
