As I get ready for our community’s annual disaster preparedness exercise, I find myself packing and charging and testing batteries. Lots of batteries. Lots of different types of batteries. No, I don’t particularly get a charge out of it! But how much we depend on our batteries in all their different forms! Batteries have progressed a long way from the days of prone-to-leak flashlight cells and barely rechargeable Ni-Cads (compared to today’s rechargeables, anyway). How about a puzzle in honor of our favorite (it seems) source of radio juice?
