For those with Emergency Lights in storage, and know the disappointment of Vampiric Batt Drain due to Drivers, switches, ect... theres an easy solution! i have a toddler and MANY of his electronic toys come with small slips of plastic to keep the batts from being drained in store or stock shelves. i save these lil plastic strips and when setting up my E-Lights (with lithiums ofcorse!) i place one of these little strips in between the Batt and the endcap, OR in my 6AAA packs, just in between a batt contact and the batt. knowing that these are there, its not hard to remember to open, pull tab, re assemble and use! with 11yr shelf life and drain prevention (thats re-usable AND/OR disposable) i feel comfort in knowing i'll have light when needed, without the worry of alkaline death or keeping batts separate from the light (which often leads to finding my expensive lith-batts in Gameboys, mp3 players, and Wiimotes)
