We had a power failure yesterday afternoon that lasted for many hours. It's 96 degrees here, and while we don't use air-conditioning, we do like to have our fan running in the bedroom. The Generator was hooked up and worked fine for the "critical" loads (Fridge, Freezer, Well Pump and Septic Pump) but I was a bit disappointed in myself for not having batteries dedicated to emergency supplies - yes, I was actually caught with (gasp) dead batteries in a lantern. How embarassing. I did have spares from the shop - but really, how could this have happened?
The way it happened was, about a year ago, I needed batteries "just for now" and rather than getting some from the store, I did what we're all always tempted to do - I pulled them from the emergency kit "for now" and forgot to replace them.
I used to "lock" my emergency kits with nylon wire ties...I'm going back to that.
