if my car's electics are on for more than 3 mins without the car being on, then I get a discharged battery warning


it's died on my over 6 times in the past year I've owned the car

They won't replace it

So I always keep a jump starter in my trunk, and hook it up to a tender if I'm not going to be driving it for a couple days
if it sits for more than 5 or so days, the battery is dead dead, won't even unlock.

car has about 15k miles in 14 months... and lives life in the high RPMs with plenty of highway driving
