I'll admit that I'm not the best ar maintainingg my preperations, found my big maglite in the garage recently with dead and leaked batteries, had to scrape the crap out of the tube before I could put new batteries in. But on the other hand I have two flashlights in my pockets, more in my truck, more in my "prep drawer" at home and spare batteries in both places as well so if I let one slip I have others to fall back on.
