I had a 6 cell boom box that I kept plugged in, out in my garage. I figured it would be good during a power outage, so I kept batteries in it. Once when I tried to use it powered with battery power, I discovered that the batteries were dead.
KIDS!!!
I decided to put a small thin piece of plastic between the battery contact and the radio contact to break the connection. This way I could store fresh batteries in the unit, and the kids will think that they are dead, and will take the effort to plug the radio in.
Years later... those batteries were still fresh.
I don't have any deoixIT but I do have a bottle of CRC contact cleaner.

I don't recall ever using it on batteries, I suppose if I suspected oxidation, I've rubbed them on my jeans.
Regarding OCD, I suspect that I have a touch of it. I purposefully decided NOT to play golf, because it appears to be an addictive sport. Thankfully, for me, it is very mild, if at all.
There was a fine gent who often parked his car in front of my office. He would get out of his car and check that the door was locked, he'd then walk around the car and check each door, and the trunk, he'd circle the car twice.
My wife, as a child, had a negative experience with fire, and would never leave the house without first checking the knobs on the gas kitchen stove, to make sure that it was off. I guess childhood experiences can be the basis for mild OCD, without being classified.
