Do you work for Energizer? Ray-O-Vac? I just put batteries in my flashlight that had a "Best Used by:" date of 2002! They work great and have been fine for the last three weeks! Throwing out batteries after three months is wasteful.Like today I change all my batteries in my flashlights, radios etc. Make yourself a calendar. Best way is Jan1, APr1, July 1, Oct 1 rotate food and water and batteries.
