Book matches were patented on this day in 1892. Ever since, matches have been handy items to have around when nasty weather causes a blackout. But a sufficient supply of batteries is even better when you're left without power and in the dark for many hours. But there are misconceptions about keeping back-up batteries.

But, when storing batteries loose, as in a drawer, keep them away from metal objects. Such objects can drain their power over time should they touch the batteries. Thus, keeping them in their original packaging is a good idea. Will storing them in the refrigerator extend their life? Experts say no; room temperature is just fine. And that's the On The House tip for today.
