Went for a flashlight a few nights ago...and they were all in the same place (far from where I was)...and none with charged batteries. Time to add that to the monthly 'check' list.
I have plenty -- Just have to learn not to store them all in the same drawer.
You noted a common problem. No matter how much I say I'll check flashlights regularly, I end up slacking off eventually.
What I've decided to do is keep a fully functioning flashlight in my personal man bag at all times. I also keep fresh batteries in a spot I could find in the dark. As for the flashlights around the house, I can try to keep their batteries fresh, but I'm realistic with myself.
