Battery drain issue!
I’ve read a few threads about battery drain issues, and can’t find anything that’s a physical fix... basically my battery was being stable for about 3 months after replacing it, and one day I was washin my DII and it wouldn’t start after washing it. I know it wasn’t the battery, because I tested it and charged it multiple times, so I went thru the fuses, and unplugged some until the battery stopped draining, turns out the one that was for just the front A/C and heating system was the one draining the battery. Well with it being Colorado in the winter I NEED the heater and if I plug it back it, boom it drains, need help and need to find a fix ASAP!

I had a persistent drain that was proving impossible to find. After lots of headaches and failed attempts at a true fix, I finally bit the bullet and bought a Battery Brain ( https://www.batterybrain.eu/our-products/ ). Should have done it after the first failed attempt. Easy to install, easy to use, and hasn't failed me yet. I haven't forgotten to manually disconnect when I leave so I haven't personally tested the auto-disconnect. Living in Wyoming with cold 8 month winters makes it easier to justify. I know my battery will start in the morning, no matter how long since I've last driven! Only downsides are resetting the clock/ect, and having the security system disabled when the car is off, but a thief could not steal the car without removing the brain and reconnecting the battery normally, as well as enter the security code when (if!) they finally get it reconnected. So in my mind I just traded my alarm system for a safer hard disconnect (when was the last time you called the cops when you heard a car alarm?). The final downside, you have to know and enter your code every time you reconnect the battery.
That said, having used it for ~8 months now, the added steps are just part of my routine and i barely notice them. All my missing stress of an electrical drain, however, is definitely noticed!

Since it's a battery disconnect your battery should last about as long as it would in storage (about 2-3% discharge per month). I live in a small town and go weeks without driving it, even in the dead of winter. If your battery isn't shot than 8 hours shouldn't be any problem at all. If you decide to get one let me know and I'll send you a picture of my set up. If your positive battery lead is as short as mine it's a bit of a puzzle to get it connected.
