Default HELP! Likely Culprit for current draw? Garaged Cobra!

Something is draining my battery if it sits for more than 5 days? I've had it tested twice and it checks out fine, my Cobra isn't a daily driver anymore just maybe once a week for a 10 mile cruise, is this common? Do I need a trickle charger or something? The guy at AutoZone talked about testing for Millivolts after the positive post is removed from the battery for about an hour?

remove the positive terrminal and wait about an hour for everything to go into sleep mode. Hook up a test light between the cable and the battery terminal and star pulling fuses until the light goes out . That will tell what circuit to start further testing

The only alarm is the factory PATS... When I tried to start it the other day the dome light etc.. worked but the starter just clicked, the week before it was Totally Dead, the remote wouldn't even unlock the door?

What kind and how fresh is the battery. In my experience Red Tops Optimas are the worst! When I had my GN it sat on time for 2 mos in the garage and it would fire right up. Run / drive it for a while to recharge park it, less than a week it wouldnt start. Trickle charge for a couple days, start / run it, the NEXT day, it was done wouldnt do anything. I had several Red Tops do this over a 2-3 year period

Tis' true. There badass batteries, but when they die, THEY DIE. No notice, no warning.

Just get one of the Braille Batteries! It'll fix ya' right up and then you never have to worry about it again!

I would at least make sure it doesnt have a draw before you condemn the battery

Thanks fuelie, like I said it's been tested GOOD twice in the last month, it's a Duralast RedTop! I'm gonna do some voltmeter tests tomorrow to pinpoint the issue!

Worst case scenario, bring it by my work and we will amp it down. See if, and how much it is pulling when its off.
