Battery dying after a few days of non-use

I'm new to the forum. Bought an 06 TJ a month ago as a fun second car. I have had two instances where it has not been driven for a 3-5 days and when I get back in, the battery is dead. The first time it happened, I just replaced the existing battery ($220), so it's only a few weeks and I know that is not the issue. Any thoughts?

Could be a couple things. First, are you driving the Jeep enough to keep the battery charged? Second, have you added any electronic/electrical doo-dads that could be draining the battery, possibly from improper installation so they are never shut off?

Are your battery connections clean and tight?

It could be from a bad alternator but that wouldn't be one of my first suspicions.

When you have a choice, buy American.

Thanks Jerry, but I don't think it's the battery and I haven't added anything. Just saw the fog lamps switching on and off by themselves and I can get it to stop by fiddling with the stalk, so I pulled the fuse out but now when I get into the car, the speedo, tacho etc flicker back and forth even without the key in the ignition. I'm not a mechanic, but I'm guessing I have a short. It should be covered by my warranty, so I'll just let the dealer figure it out on Monday.

What fuse did you pull out? To disable the fog lights pull the relay. There is no dedicated fuse for the fog lights, at least not in my ’05 which has the same circuit, I think.

The switch is known to fail causing the fogs to stay on. You need a new left multi function switch to fix that. There is a way to repair the switch but if you have a warranty let them replace the switch.

Check your engine ground too. A buddy was having a similar problem and the engine to frame ground was loose.

My car has a parasitic draw with all the equipment in it. I went to Harbor Freight and got a 15.00 solar charger and plugged it in (plugs directly into accessory plug that us old dudes call cigarette lighters lol. No more dead battery after my off cycle. Might try that until you figure out what the problem is.

My daily driver is a 2015 JKU on 35's 4.56 and Trutracs, My trail rig is my 1997 TJ on 35's 4.88 and Trutracs plus a pile of cash....
