Fully charged battery dies after a few days of not starting it
Is this normal? It will be 100% charged and after 2 days of not starting it, When I do go to start it it is dead and needs to be recharged. Do I need a new battery? Is there a parasitic draw? It's on my 1991 jeep cherokee , not a stock battery. Bigger than the stock one taken from my dads f150

It's got to be a parasitic draw. I remember reading a lot of folks have this problem with the door wiring (so if you have power windows/locks) and someone had the issue with the tailgate wiring (it wasn't closing all the way I believe).
You could/should probably check the battery. Autozone will do a load test right on the car for free, but my money is on parasitic draw. I had that problem with my 00 TJ due to the dealer installed alarm I suspect.

A parasitic draw will wipe a battery quickly. Unless that battery can handle deep cycling, it's pretty much going to be garbage after a few times of it dying. Time to hunt down that parasite.

I got caught by the underhood light. It's some kind of metal slider that got stuck in place. It essentially was shorting the battery. Died a few times before I traced it to that light. I'd get some disconnects until you find the problem. that should keep it from dying every night.

How old is the battery? If you have a used batter from a different vehicle, I would start there. Especially if it has been deep cycled a few times anyhow, it is probably toast.

test for parasitic draw. Plenty of videos on YouTube. If it's not that then test the battery. I would likely guess it's just the battery but won't hurt to test first.

I just noticed the post on parasitic drain was started by you as well. Follow instructions in the video posted there. Good luck.
