As an experimenting kind of kid, I discovered that two 9V batteries plugged into each other just creates a lot of heat pretty quickly, and ruins the batteries. Fast forward to the present, and I've uncovered a new find... for me anyway.
I built another one of my battery driven, LED flashlight projects this week, which uses two 9V's in parallel for double runtime. The only two 9V's in the house checked out at 7.9V, and the other was 8.9V. Ten cool points to all who guess where they both ended up after a few days.
Don't laugh too hard... it was a cool discovery... lol. And now it sorta' makes sense why it happened, but it wasn't expected. Of course, the flashlight did not have to be on for the V's to balance out.
Ya' learn something new every day.
