Battery Losing Charge

I own a 2006 LJ I use only a couple times per month on weekends for fun. I have a problem keeping my battery charged and now have to hook the charger up to it the evening before I want to go out riding. The problem with the battery seems to have started about two years after I had aftermarket Halo lights installed professionally. I make sure the lights are turned off when I park it in the garage so I know they are not draining the battery.

The original factory battery lasted from 2006-~ 2011. Since 2011 Iíve had to replace the battery every 2-3 years, with very limited cranking and usage.

Is there a way I can check for a slow drain on the battery while parked in the garage? I canít image buying 2-3 bad batteries in a row. So there must be a slow drain in the Jeep somewhere. Thoughts?

It'd help if you would drive the Jeep more to keep the battery topped up, another option would be to use a battery tender whenever you're not driving it. That aside, read through the information in the following link for how to find a parasitic drain (starts about halfway down the page).

Is there a relay in the halo circuit? If so the installer (usually a kid who is inept electrically) might have wired the relay incorrectly so it is shut off to turn the halos on but the relay is powered on to shut the halos off. The relay being miswired so it stays on when the halos are off would cause a battery drain.

Also, what brand of batteries have you been installing?

When you have a choice, buy American made.

How do you know the batteries where bad? They probably where just discharged.

Sherlock Holmes won't be needed here.
As we say in the trade 'self inflicted' but you know where to start. Anything else added audio, alarm, something plugged into DLC?

When I see the price of OEM I think aftermarket.
